The function of the citric acid cycle is
the harvesting of high-energy electrons from carbon fuels
. Note that the citric acid cycle itself neither generates a large amount of ATP nor includes oxygen as a reactant (Figure 17.3).
What is the main function of the citric acid cycle chegg?
Primary function of Citric Acid cycle is
the production of ATP
. It is the final common pathway for oxidation of carbohydrate, lipids and protein via acetyl CoA or intermediate of the cycle. Citric Acid cycle is an Amphibolic process, which describes a biochemical pathway that involves both catabolism and anabolism.
What is the function of the citric acid cycle quizlet?
The function of the citric acid cycle is
to harvest high-energy electrons from carbon fuels
.
What are the two main benefits of the citric acid cycle?
The two main purposes of the citric acid cycle are: A) synthesis of citrate and gluconeogenesis. B)
degradation of acetyl-CoA to produce energy and to supply precursors for anabolism
.
Why is it called citric acid cycle?
The citric acid cycle is called a cycle
because the starting molecule, oxaloacetate (which has 4 carbons), is regenerated at the end of the cycle
.
What happens in the citric acid cycle?
The citric acid cycle: In the citric acid cycle,
the acetyl group from acetyl CoA is attached to a four-carbon oxaloacetate molecule to form a six-carbon citrate molecule
. Through a series of steps, citrate is oxidized, releasing two carbon dioxide molecules for each acetyl group fed into the cycle.
What is the primary function of the citric acid cycle in ATP production what other vital role is served by the citric acid cycle chegg?
1-The oxidation reactions of the citric acid cycle provides oxygen for electron transport and ATP synthesis. 2-
The reduction reactions of the citric acid cycle produce ATP molecules
. 3-In the citric acid cycle, oxaloacetate is regenerated, which is available to pick up acetyl CoA and start the cycle again.
Which of the three major stages of metabolism includes the citric acid cycle?
Which of the three major stages of metabolism includes the citric acid cycle?
carbon dioxide and energy
.
What products of the citric acid cycle are needed for the electron transport chain?
The citric acid cycle involves eight chemical reactions that produce carbon dioxide,
ATP, NADH and FADH2
. The NADH and FADH2 are electron carriers that can be used by the electron transport chain (ETC).
What occurs in the first step of the citric acid cycle?
In the first step of the citric acid cycle,
acetyl CoAstart text, C, o, A, end text joins with a four-carbon molecule, oxaloacetate, releasing the CoAstart text, C, o, A, end text group and forming a six-carbon molecule called
citrate. Step 2. In the second step, citrate is converted into its isomer, isocitrate.
What is another name for the citric acid cycle?
The citric acid cycle (also called as
Krebs cycle or tricarboxylic acid cycle
) takes place in the mitochondria and is an integral part for the generation of adenosine triphosphate (ATP).
What are the 10 steps in glycolysis?
- Step 1: Hexokinase. …
- Step 2: Phosphoglucose Isomerase. …
- Step 3: Phosphofructokinase. …
- Step 4: Aldolase. …
- Step 5: Triosephosphate isomerase. …
- Step 6: Glyceraldehyde-3-phosphate Dehydrogenase. …
- Step 7: Phosphoglycerate Kinase. …
- Step 8: Phosphoglycerate Mutase.
Where is ATP synthase located?
In eukaryotes, the ATP synthase complex is located in
the inner membrane of mitochondria
, with ATP synthesis reaction occurring on the membrane side toward matrix compartment.
How many ATPS can be produced from one molecule of glucose aerobically?
Biology textbooks often state that
38 ATP molecules
can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
What reduced coenzymes provide the electrons for electron transport?
Reduced coenzymes include
NADH, FADH2 and coenzyme Q
. Most organisms carry out aerobic respiration, where oxygen is the final electron acceptor and water is the reduced form.
Is Succinyl-CoA an intermediate?
Succinyl-CoA is an
important intermediate in the citric acid cycle
, where it is synthesized from α-Ketoglutarate by α-ketoglutarate dehydrogenase (EC 1.2. 4.2) through decarboxylation, and is converted into succinate through the hydrolytic release of coenzyme A by succinyl-CoA synthetase (EC 6.2.
