The citric acid cycle, where acetyl CoA is modified in the mitochondria to produce energy precursors in preparation for the next step.
Oxidative phosphorylation
, the process where electron transport from the energy precursors from the citric acid cycle (step 3) leads to the phosphorylation of ADP, producing ATP.
How many ATP are produced in the citric acid cycle?
2 ATPs
are produced in the TCA cycle per glucose molecule (2 acetyl CoA). ATP is produced when Succinyl CoA produces succinate by the enzyme succinyl CoA synthetase. It is important to note that most of the ATP produced in cellular respiration account for oxidative phosphorylation in the electron transport chain.
How is ATP produced in the citric acid cycle quizlet?
The citric acid cycle completes glucose oxidation. The energy released by the
oxidation of one acetyl CoA molecule
is used to produce 3 NADH, 1 FADH2, and 1 GTP, which is then converted to ATP.
Does the citric acid cycle use ATP?
The TCA cycle metabolizes acetate derived from carbohydrates, proteins, and fats to form adenosine triphosphate (ATP)
, the body’s energy currency. Oxidation of one glucose molecule through the combined action of glycolysis, the TCA cycle, and oxidative phosphorylation yields an estimated 30–38 ATP molecules.
What energy intermediates are produced in the citric acid cycle?
During what stage are these intermediates produced? Explanation: The citric acid (Krebs) cycle and glycolysis yield high energy intermediates that can then be used to make ATP. Each turn of the citric acid cycle generates
NADH and FADH
2
, and each cycle of glycolysis generates NADH.
How many ATP are produced?
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).
How many ATP are produced in TCA cycle from each acetyl CoA?
Acetyl CoA produces
12 ATP molecules
accounting for 3 NADH (9 ATP), 1 FADH2 (2 ATP) and 1 GTP (1 ATP) in the TCA cycle and oxidative phosphorylation in the electron transport system.
What is produced at the end of the citric acid cycle?
Overall, one turn of the citric acid cycle releases two carbon dioxide molecules and produces three NADHstart text, N, A, D, H, end text, one FADH2start text, F, A, D, H, end text, start subscript, 2, end subscript, and
one ATPstart text, A, T, P, end text or GTPstart text, G, T, P, end text

What process is used to make ATP in glycolysis and the citric acid cycle?
In aerobic conditions, pyruvate enters the citric acid cycle and undergoes
oxidative phosphorylation
leading to the net production of 32 ATP molecules. In anaerobic conditions, pyruvate converts to lactate through anaerobic glycolysis. Anaerobic respiration results in the production of 2 ATP molecules.
How is ATP made during glycolysis quizlet?
During glycolysis,
high-energy phosphate groups from the intermediate molecules are added to ADP to make ATP
. If respiration does not occur, NADH must be reoxidized to NAD+ for reuse as an electron carrier for glycolysis, the cell’s only mechanism for producing any ATP, to continue.
How is ATP made from cellular respiration?
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way,
some ATP is produced directly in the reactions that transform glucose
. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
How is ATP produced by glycolysis?
Anaerobic glycolysis serves as a means of energy production in cells that cannot produce adequate energy through oxidative phosphorylation. In poorly oxygenated tissue, glycolysis produces 2 ATP by
shunting pyruvate away from mitochondria and through the lactate dehydrogenase reaction
.
How is ATP produced in the citric acid cycle electron transport system and oxidative phosphorylation?
The citric acid cycle is a series of chemical reactions that removes high-energy electrons and uses them in the electron transport chain to generate ATP.
One molecule of ATP (or an equivalent) is produced per each turn of the cycle
.
How many ATP are produced in glycolysis and TCA cycle?
1 Answer. In
glycolysis net production of 2 ATP
. Krebs cycle production is 1 ATP(1 molecule of GTP) and with ETS total production is 12Atp.
How many ATP are produced in aerobic respiration?
| Aerobic | Products ATP, water, CO 2 | Location Cytoplasm (glycolysis) and mitochondria | Stages Glycolysis (anaerobic), Krebs cycle, oxidative phosphorylation | ATP produced Large amount ( 36 ATP ) |
|---|
Why citric acid cycle is called TCA cycle?
Citric acid is a so-called tricarboxylic acid, containing three carboxyl groups (COOH)
. Hence the Krebs cycle is sometimes referred to as the tricarboxylic acid (TCA) cycle.
How many ATP molecules are produced in the citric acid cycle during the complete oxidation of one glucose molecule?
So, the correct option is ‘
38
‘.
How is ATP synthase involved in making energy available to the cell?
How is ATP synthase involved in making energy available to the cell?
ATP synthase is a large protein through which hydrogen ions (H+) pass, converting ADP into high-energy ATP
.
Which of the following processes produces the most ATP?
Explanation: The
electron transport chain
generates the most ATP out of all three major phases of cellular respiration. Glycolysis produces a net of 2 ATP per molecule of glucose.
How is citric acid produced?
Citric acid is the most important organic acid produced in tonnage and is extensively used in food and pharmaceutical industries. It is produced mainly by
submerged fermentation using Aspergillus niger or Candida sp. from different sources of carbohydrates, such as molasses and starch based media
.
