Sentences with phrase «citric acid cycle»

As discussed by Robergs and Roberts [22], amino acid catabolism during exercise is important for three reasons: 1) for free energy during exercise to fuel muscle contraction; 2) to increase concentrations of citric acid cycle intermediates and therefore support carbohydrate and lipid catabolism; and 3) to serve as gluconeogenic precursors.

Those moments stood out: «Blah blah citric acid cycle blah blah succinic dehydrogenase blah blah DOONESBURY CARTOON blah blah pyruvate.»

In skeletal muscle, fat certainly does not burn in a carbohydrate flame, as skeletal muscle does not have sufficient quantities of the enzymes to convert glycolytic intermediates into molecules that can be transported into the mitochondria to supplement citric acid cycle intermediates.

This synthesis kicks off the citric acid cycle (or Krebs cycle), a set of chemical reactions that creates usable energy from fat, protein and carbohydrates.

The other subpopulation preferentially imports lactate, using it as the main energy source by harnessing part of the citric acid cycle.

It's particularly because components of the citric acid cycle, specifically isocitrate dehydrogenases 1 and 2 (IDH1 and IDH2) have recently emerged as oncogenes that are recurrently mutated in gliomas and leukemias.

Finally, studies have shown that leucine promotes energy partitioning from fat cells to muscle cells, thereby decreasing energy storage and encouraging the body to burn fat cells as fuel, with one large study providing irrefutable evidence that leucine supplementation fuels the citric acid cycle which facilitates fat oxidation.

Aerobic respiration produces creates around 17 times more energy as ATP through reactions within the mitochondria called the Krebs or citric acid cycle and the Electron Transport Chain than the aerobic glycolysis that takes place in the muscle tissues outside the mitochondria (Fig. 1).

Since vitamin B12 is important for maintaining proper supplies of succinyl - coA in the citric acid cycle, it is important for supporting all aerobic energy metabolism.

At the heart of this process is a metabolic cycle called the citric acid cycle and included within this cycle is a molecule called succinyl - coA.

On the other hand, a LCHF diet forces the body into oxidation: fatty acids break down into Acetyl - CoA, which goes directly into the Citric Acid Cycle.

It is an important element in the Krebs», or citric acid cycle, which creates energy for both aerobic and anaerobic activities.

Step 4: The pyruvate is at the beginning of a chain reaction called the «Citric Acid Cycle» or «Krebs Cycle.»

Carnitine transports long - chain acyl groups from fatty acids into the mitochondrial matrix, so that they can be broken down through β - oxidation to acetate to obtain usable energy via the citric acid cycle.

Amino acids are broken down to carbon units that enter a metabolic pathway called the citric acid cycle, which provides precursors that are incorporated into lipids.

Likewise, glucose derived from dietary carbohydrate is broken down in a pathway called glycolysis, and the product of glycolysis can enter the citric acid cycle and then be incorporated into lipids.

This non-essential amino acid has an important role in the Krebs cycle, also known as the citric acid cycle.

Asparagine also helps to form other chemicals that take part in the Krebs cycle (also called the citric acid cycle).

Malic acid is produced in our bodies in the Citric Acid Cycle and in vegetables and fruits, especially apples.

The autoimmune protocol is likewise rich in cofactors for the citric acid cycle, the process which produces high - energy reduced coenzymes that donate electrons into the electron transport chain in order to generate cellular energy.

[78] All amino acids are synthesized from intermediates in glycolysis, the citric acid cycle, or the pentose phosphate pathway.

[7] Amino acids also contribute to cellular energy metabolism by providing a carbon source for entry into the citric acid cycle (tricarboxylic acid cycle), [8] especially when a primary source of energy, such as glucose, is scarce, or when cells undergo metabolic stress.

DMSA is an analogue of many intermediates in the Krebs or citric acid cycle, a central pathway for the metabolism of fats, carbohydrates, and amino acids.

Source of carbon and nitrogen — Glutamine donates carbon to the citric acid cycle and nitrogen for the synthesis of purines

Both items contribute to the mitochondria not obtaining enough pyruvate and this hinders both the Citric Acid Cycle and the Electron Transport Chain and thus blocks the production of an adequate amount of ATP in the mitochondria.

When muscle glycogen and blood glucose concentrations are low, the incorporation of the carbon skeletons from amino acids into the citric acid cycle is important for maintaining the concentrations of the intermediates, and therefore a high rate of mitochondrial respiration.

In the liver in the well - fed state, acetyl CoA formed during the β - oxidation of fatty acids is oxidized to CO2 and H2O in the citric acid cycle.

Even under conditions of extreme ketoacidosis there is no significant membrane barrier to glucose uptake — the block occurs «lower down» in the metabolic pathway where the excess of ketones competitively blocks the metabolites of glucose entering the citric acid cycle.

I have delivered term papers, dissertations, assignments, case studies on several topics and some of them are Atomic Theory, Ionic Bonding, Endothermic & Exothermic Reactions, Citric Acid Cycle, etc..
