citric acid cycle

Question 1

Citric Acid cycle

Answer 1

• Acetyl group of acetyl-CoA is completely oxidized to carbon dioxide
• the chemical energy is transferred to ATP by substrate-level phosphorylation and to the reduced electron carriers NADH and FADH2
• supplies electrons to the ETC

Question 2

how is ATP made in the citric acid cycle?

Answer 2

substrate level phosphorylation

Question 3

carbons in the citric acid cycle

Answer 3

All 6 carbons originating from 1 glucose molecule are completely oxidized to
CO2!

Question 4

inputs and outputs for the citric acid cycle

Answer 4

inputs:
- acetyl CoA
- FAD
- NAD+
- ADP (or GTP)

outputs
- CoA
- NADH
- FADH2
- CO2
- ATP (or GTP)
