What else can I help you with?
When can the Krebs cycle not occur?
when oxygen is not present
How many ATP molecules are produced from the kreb cycle?
The Krebs cycle produces 1 ATP molecule per cycle through substrate-level phosphorylation. Since the cycle completes twice for each glucose molecule entering glycolysis, a total of 2 ATP molecules are generated from the Krebs cycle per glucose molecule metabolized.
What products of the Krebs cycle are used in the electon transport?
In the Krebs cycle NAD+ is reduced to NADH. This is one of the electron carriers. Also FAD is reduced to FADH2 which is the other electron carrier produced during the Krebs cycle.
How many NADH's are generated after one cycle of the TCA?
Two molecules of NADH are generated after one cycle of the TCA (Krebs) cycle.
How many carbons from one glucose molecule enter one round of the Krebs cycle?
just one
What are the similarities between the Krebs Cycle and the Calvin cycle?
Similarity: They are both cycles, therefore both have a reactant that s regenerated. In the Krebs Cycle, oxaloacetate is regenerated. In the Calvin cycle, RuBP is regenerated (ribulose 1, 5-bisphosphate). Difference: Glucose is completely broken down in the Krebs Cycle to carbon dioxide, which in the Calvin Cycle, glucose is made as a product.
What is the molecule that is regenerated with every turn of the Krebs cycle?
Each turn of the Kreb's cycle must regenerate oxaloacetate.
When can the Krebs cycle not occur?
when oxygen is not present
How many ATP molecules are produced from the kreb cycle?
The Krebs cycle produces 1 ATP molecule per cycle through substrate-level phosphorylation. Since the cycle completes twice for each glucose molecule entering glycolysis, a total of 2 ATP molecules are generated from the Krebs cycle per glucose molecule metabolized.
Which one is formed during the Krebs cycle FADH2 or pyruvic acid?
FADH2 since pyruvic acid is needed to START the Krebs cycle
What products of the Krebs cycle are used in the electon transport?
In the Krebs cycle NAD+ is reduced to NADH. This is one of the electron carriers. Also FAD is reduced to FADH2 which is the other electron carrier produced during the Krebs cycle.
How many times does the Krebs cycle run to break down one glucose molecule?
The Krebs cycle runs twice to break down one molecule of glucose.
How many ATP molecules are made from substrate-level Phosphorylation?
One molecule of ATP is typically produced during substrate-level phosphorylation. This occurs when a high-energy phosphate group is transferred directly from a substrate molecule to ADP, forming ATP.
How many ATP molecules are produced for every pyruvic acid molecule that enters the Krebs' cycle?
The energy tally from one molecule of pyruvic acid is 4 NADH, 1 FADH₂ and 1 molecule of ATP.
How many carbons from one glucose molecules enter one round of Krebs cycle?
No
How many NADH's are generated after one cycle of the TCA?
Two molecules of NADH are generated after one cycle of the TCA (Krebs) cycle.
How many carbons from one glucose molecule enter one round of the Krebs cycle?
just one
