Eat protein and do weight training. Your metabolism increases whenever you eat, digest, and store food, a process called thermic effect of food. Protein has a higher thermic effect compared with fats and carbohydrates because it takes longer for your body to burn protein and absorb it.

It's not clear how much of an effect protein has on metabolism, but studies suggest the best approach is to combine adequate protein intake with weight training, which increases muscle mass — and that also can boost metabolism.

Drink green tea. Studies have found green tea contains a compound called epigallocatechin gallate, which may increase the calories and fat you burn. A meta-analysis published in Obesity Reviews found that consuming about milligrams of epigallocatechin gallate the amount in about three cups of green tea helped boost metabolism enough to burn an average of extra calories a day.

These observations led Peter Mitchell, in , to propose his revolutionary chemiosmotic hypothesis. The reaction catalyzed by succinyl-CoA synthetase in which GTP synthesis occurs is an example of substrate-level phosphorylation.

Acetyl-CoA enters the tricarboxylic acid cycle at the top of the diagram and reacts with oxaloacetate and water H 2 O to form a molecule of citrate and CoA-SH in a reaction catalyzed by citrate synthase. Next, the enzyme aconitase catalyzes the isomerization of citrate to isocitrate.

Succinyl-CoA reacts with GDP and inorganic phosphate P i to form succinate and GTP. This reaction releases CoA-SH and is catalyzed by succinyl-CoA synthetase.

In the next step, succinate reacts with FAD to form fumarate and FADH 2 in a reaction catalyzed by succinate dehydrogenase. Fumarate combines with H 2 O in a reaction catalyzed by fumerase to form malate.

Then, oxaloacetate can react with a new molecule of acetyl-CoA and begin the tricarboxylic acid cycle again. The diagram shows the molecular structures for citrate, isocitrate, alpha-ketoglutarate, succinyl-CoA, succinate, fumarate, malate, and oxaloacetate. The enzymes that act at each of the eight steps in the cycle are shown in yellow rectangles.

In aerobic respiration or aerobiosis, all products of nutrients' degradation converge to a central pathway in the metabolism, the TCA cycle. In this pathway, the acetyl group of acetyl-CoA resulting from the catabolism of glucose, fatty acids, and some amino acids is completely oxidized to CO 2 with concomitant reduction of electron transporting coenzymes NADH and FADH 2.

Consisting of eight reactions, the cycle starts with condensing acetyl-CoA and oxaloacetate to generate citrate Figure 3. In addition, a GTP or an ATP molecule is directly formed as an example of substrate-level phosphorylation.

In this case, the hydrolysis of the thioester bond of succinyl-CoA with concomitant enzyme phosphorylation is coupled to the transfer of an enzyme-bound phosphate group to GDP or ADP.

Also noteworthy is that TCA cycle intermediates may also be used as the precursors of different biosynthetic processes. The TCA cycle is also known as the Krebs cycle, named after its discoverer, Sir Hans Kreb.

Krebs based his conception of this cycle on four main observations made in the s. The first was the discovery in of the sequence of reactions from succinate to fumarate to malate to oxaloacetate by Albert Szent-Gyorgyi, who showed that these dicarboxylic acids present in animal tissues stimulate O 2 consumption.

The second was the finding of the sequence from citrate to α-ketoglutarate to succinate, in , by Carl Martius and Franz Knoop. Next was the observation by Krebs himself, working on muscle slice cultures, that the addition of tricarboxylic acids even in very low concentrations promoted the oxidation of a much higher amount of pyruvate, suggesting a catalytic effect of these compounds.

And the fourth was Krebs's observation that malonate, an inhibitor of succinate dehydrogenase, completely stopped the oxidation of pyruvate by the addition of tricarboxylic acids and that the addition of oxaloacetate in the medium in this condition generated citrate, which accumulated, thus elegantly showing the cyclic nature of the pathway.

When 1,3-bisphosphoglycerate is converted to 3-phosphoglycerate, substrate-level phosphorylation occurs and ATP is produced from ADP. Then, 3-phosphoglycerate undergoes two reactions to yield phosphoenolpyruvate.

Next, phosphoenolpyruvate is converted to pyruvate, which is the final product of glycolysis. During this reaction, substrate-level phosphorylation occurs and a phosphate is transferred to ADP to form ATP. Interestingly, during the initial phase, energy is consumed because two ATP molecules are used up to activate glucose and fructosephosphate.

Part of the energy derived from the breakdown of the phosphoanhydride bond of ATP is conserved in the formation of phosphate-ester bonds in glucosephosphate and fructose-1,6-biphosphate Figure 4. In the second part of glycolysis, the majority of the free energy obtained from the oxidation of the aldehyde group of glyceraldehyde 3-phosphate G3P is conserved in the acyl-phosphate group of 1,3- bisphosphoglycerate 1,3-BPG , which contains high free energy.

Then, part of the potential energy of 1,3BPG, released during its conversion to 3-phosphoglycerate, is coupled to the phosphorylation of ADP to ATP. The second reaction where ATP synthesis occurs is the conversion of phosphoenolpyruvate PEP to pyruvate.

PEP is a high-energy compound due to its phosphate-ester bond, and therefore the conversion reaction of PEP to pyruvate is coupled with ADP phosphorylation.

This mechanism of ATP synthesis is called substrate-level phosphorylation. For complete oxidation, pyruvate molecules generated in glycolysis are transported to the mitochondrial matrix to be converted into acetyl-CoA in a reaction catalyzed by the multienzyme complex pyruvate dehydrogenase Figure 5.

When Krebs proposed the TCA cycle in , he thought that citrate was synthesized from oxaloacetate and pyruvate or a derivative of it. Only after Lipmann's discovery of coenzyme A in and the subsequent work of R.

Stern, S. Ochoa, and F. Lynen did it become clear that the molecule acetyl-CoA donated its acetyl group to oxaloacetate. Until this time, the TCA cycle was seen as a pathway to carbohydrate oxidation only.

Most high school textbooks reflect this period of biochemistry knowledge and do not emphasize how the lipid and amino acid degradation pathways converge on the TCA cycle. The cell is depicted as a large blue oval.

A smaller dark blue oval contained inside the cell represents the mitochondrion. The mitochondrion has an outer mitochondrial membrane and within this membrane is a folded inner mitochondrial membrane that surrounds the mitochondrial matrix.

The entry point for glucose is glycolysis, which occurs in the cytoplasm. Glycolysis converts glucose to pyruvate and synthesizes ATP. Pyruvate is transported from the cytoplasm into the mitochondrial matrix.

Pyruvate is converted to acetyl-CoA, which enters the tricarboxylic acid TCA cycle. In the TCA cycle, acetyl-CoA reacts with oxaloacetate and is converted to citrate, which is then converted to isocitrate.

Isocitrate is then converted to alpha-ketoglutarate with the release of CO 2. Then, alpha-ketoglutarate is converted to succinyl-CoA with the release of CO 2. Succinyl-CoA is converted to succinate, which is converted to fumarate, and then to malate.

Malate is converted to oxaloacetate. Then, the oxaloacetate can react with another acetyl-CoA molecule and begin the TCA cycle again.

In the TCA cycle, electrons are transferred to NADH and FADH 2 and transported to the electron transport chain ETC. The ETC is represented by a yellow rectangle along the inner mitochondrial membrane. The ETC results in the synthesis of ATP from ADP and inorganic phosphate P i. Fatty acids are transported from the cytoplasm to the mitochondrial matrix, where they are converted to acyl-CoA.

Acyl-CoA is then converted to acetyl-CoA in beta-oxidation reactions that release electrons that are carried by NADH and FADH 2. These electrons are transported to the electron transport chain ETC where ATP is synthesized.

Amino acids are transported from the cytoplasm to the mitochondrial matrix. Then, the amino acids are broken down in transamination and deamination reactions. The products of these reactions include: pyruvate, acetyl-CoA, oxaloacetate, fumarate, alpha-ketoglutarate, and succinyl-CoA, which enter at specific points during the TCA cycle.

This pathway is known as β-oxidation because the β-carbon atom is oxidized prior to when the bond between carbons β and α is cleaved Figure 6.

The four steps of β-oxidation are continuously repeated until the acyl-CoA is entirely oxidized to acetyl-CoA, which then enters the TCA cycle.

In the s, a series of experiments verified that the carbon atoms of fatty acids were the same ones that appeared in the acids of TCA cycle.

It raises the risk of obesity, affects bone and muscle development, and impacts your metabolism. If you sit for work or are constantly seated at home, take breaks to stand or walk.

One study comparing data from Southeast Asia and the United States showed that taking a break to stand or walk every 30 minutes boosted metabolic health in older adults. Countless dietary fads promise to boost your metabolism and manage your weight.

Crash diets focusing on severe food restrictions can prevent your body from getting the nutrients it needs. Aim to eat a variety of foods that provide sufficient calories and essential vitamins and minerals. Blood flow and energy expenditure are redirected from digestion and metabolism to the muscles and the brain.

This slows your metabolic rate, and if the stress persists, this can cause long-term effects. So how can you tell if your metabolism is slow? There can be many signs, with the most common including:. The thyroid is the small, butterfly-shaped gland in your neck that regulates metabolism.

Low thyroid levels slow your metabolic function and raise the risk of complications, such as high cholesterol or coma. A big part of managing hypothyroidism and preventing these complications is boosting your metabolic rate.

Alongside a prescription of levothyroxine , a synthetic thyroid hormone, lifestyle and dietary changes that promote your metabolism play a key role. Metabolism is the process by which your body converts food into energy. Modifiable factors influencing your metabolic rate include diet, physical activity, and sleep.

Incorporating a high-protein diet, high-intensity exercise, strengthening, and better sleep habits are among the ways to boost your metabolism naturally. You may require medication if an underlying condition is affecting your metabolism.
