What else can I help you with?
Two carbon molecule that combines with a four carbon molecule already in the citric acid cycle to produce citric acid?
The two-carbon molecule that combines with a four-carbon molecule in the citric acid cycle to produce citric acid is acetyl-CoA. Acetyl-CoA condenses with oxaloacetate (a four-carbon molecule) to form citrate, the first step in the citric acid cycle.
During a single turn of the citric acid cycle what is generated?
During a single turn of the citric acid cycle, one molecule of ATP, three molecules of NADH, one molecule of FADH2, and two molecules of CO2 are generated.
What process of ATP production begins with the breakdown of pyruvic acid?
The process of ATP production that begins with the breakdown of pyruvic acid is the citric acid (Krebs) cycle. Pyruvic acid is converted to acetyl-CoA, which then enters the citric acid cycle to produce ATP through a series of chemical reactions in the mitochondria.
Pyruvic acid loses a molecule of BLANK to produce acetic acid which then enters the citric acid cycle?
Carbon dioxide. Pyruvic acid undergoes decarboxylation to lose a carbon dioxide molecule and form acetic acid. This acetic acid then combines with Coenzyme A to form acetyl-CoA, which enters the citric acid cycle.
In cellular respiration a two carbon molecule combines with a four carbon with four carbon molecules to form citric acid as part of?
In cellular respiration, a two-carbon molecule (acetyl-CoA) combines with a four-carbon molecule (oxaloacetate) to form citric acid in the first step of the citric acid cycle (Krebs cycle). This process occurs in the mitochondria and is essential for the production of ATP through the oxidation of acetyl-CoA.
Two carbon molecule that combines with a four carbon molecule already in the citric acid cycle to produce citric acid?
The two-carbon molecule that combines with a four-carbon molecule in the citric acid cycle to produce citric acid is acetyl-CoA. Acetyl-CoA condenses with oxaloacetate (a four-carbon molecule) to form citrate, the first step in the citric acid cycle.
How many CO2 are produced during the transition reaction and the citric acid cycle per glucose molecule?
Two Co2 molecules are produced per citric acid cycle. Since the citric acid cycle occurs twice with every molecule of glucose metabolized, a total of 4 C02 molecules are produces for every glucose molecule
Why is the Citric Acid cycle called a cycle?
The Citric Acid cycle is called a cycle because it is a series of chemical reactions that regenerates its starting molecule, oxaloacetate, at the end. This allows the cycle to continue repeatedly as long as there are substrates available.
How much ATP is made by the citric acid cycle?
The citric acid cycle generates 1 ATP molecule per turn through substrate-level phosphorylation. However, since the cycle turns twice for each glucose molecule, a total of 2 ATP molecules are produced per glucose molecule during the citric acid cycle.
During a single turn of the citric acid cycle what is generated?
During a single turn of the citric acid cycle, one molecule of ATP, three molecules of NADH, one molecule of FADH2, and two molecules of CO2 are generated.
What molecule moves into the Krebs cycle?
Pyruvate -> Acetyl CoA -> Citrate which is used by the Krebs or Citric Acid Cycle.
What cycle produces the most NADH?
Electron Transport Chain. It produces 32 while the citric acid cycle (your teacher might call it the Krebs Cycle) produces 2 and glycolysis produces 2 (all those numbers are per ONE GLUCOSE MOLECULE) Electron Transport Chain. It produces 32 while the citric acid cycle (your teacher might call it the Krebs Cycle) produces 2 and glycolysis produces 2 (all those numbers are per ONE GLUCOSE MOLECULE)
What process of ATP production begins with the breakdown of pyruvic acid?
The process of ATP production that begins with the breakdown of pyruvic acid is the citric acid (Krebs) cycle. Pyruvic acid is converted to acetyl-CoA, which then enters the citric acid cycle to produce ATP through a series of chemical reactions in the mitochondria.
How many molecules of FADH2 are produced by the complete oxidation of one acetyl group by the citric acid cycle?
One acetyl group produces 1 molecule of FADH2 in the citric acid cycle.
What is the citric acid cycle also known as?
Krebs cycle (aka citric acid cycle, aka tricarboxylic acid cycle)
How many turns of the citric acid cycle are required for a single glucose to be metabolized?
Two turns of the citric acid cycle are required for a single glucose molecule to be fully metabolized. This is because one glucose molecule is broken down into two molecules of pyruvate during glycolysis, and each pyruvate molecule enters the citric acid cycle to produce energy.
Pyruvic acid loses a molecule of BLANK to produce acetic acid which then enters the citric acid cycle?
Carbon dioxide. Pyruvic acid undergoes decarboxylation to lose a carbon dioxide molecule and form acetic acid. This acetic acid then combines with Coenzyme A to form acetyl-CoA, which enters the citric acid cycle.
