Bio 107 Exam 3 Ch 7

What enters the citric acid cycle?

Acetyl CoA from pyruvate oxidation

What’s the products from the citric acid cycle for each glucose?

4 ATP, 6 CO2, 2 FADH, 10 NADH

What does the citric acid cycle do?

Oxidizes the acetyl group from pyruvate to make NADH and FADH for the ETC

What happens during the electron transport chain?

The ETC is a series of membrane-bound electron carriers, and electrons from NADH and FADH are transferred to different complexes which build a proton gradient, and go to the ATP synthase.

How much ATP is produced per glucose molecule in bacteria?

32

How much ATP is created per glucose molecule in eukaryotes?

30

The final electron acceptor in the ETC is..

Oxygen, and it makes water

Step 1 of the Citric Acid Cycle

condensation, acetyl-CoA combines with oxaloacetate to make citrate

Steps 4,5,7 and 9 of the Citric Acid Cycle

oxidation of sugar

Steps 4 and 5 of the Citric Acid cycle

release of CO2

Step 6 of the Citric Acid Cycle

Substrate level phosphorylation — ATP produced!

Substrate level phosphorylation

transfer phosphate group from organic molecule directly to ADP
