Krebs Cycle (Section 2)

Question 1

What does it do?

Answer 1

allows for oxidation of acetyl-CoA to release energy during aerobic exercise. It’s objective is to remove CO2, generate H’s, and regenerate oxaloacetate.

Generates 3 NADH, 1 FADH, and 1 GTP

Question 2

Why is it capable of being the central cog in the metabolic pathways?

Answer 2

it’s the second stage of cellular respiration. Oxidation of molecules is primarily used to transform the energy contained in these molecules into ATP

Question 3

Krebs cycle produces 1 ATP (in the form of?) and how many NADH’s/FADH’s for each AcCoA?

Answer 3

produces 1 ATP in the form of GTP

3 NADH and 1 FADH

Question 4

What is NADH and FADH? (Pathway(s)?)

Answer 4

They’re both coenzymes used to transport electrons to the ETC

NADH Pathways: glycolysis and Krebs cycle
FADH Pathway: Krebs cycle

Question 5

Roles of NADH and FADH

Answer 5

responsible for donating electrons to the ETC by providing a hydrogen molecule to the O2 to create H2O

Question 6

How many ATP are produced when H’s move through the ETC?

Answer 6

3 (total 2.5-3) ATP for NADH

2 (total 1.5) ATP fpr FADH
