Cell Respiration: Part 6 : Aerobic Respiration: Part 1: Krebs Cycle Flashcards
1
Q
Where does the Krebs Cycle occur?
A
In the Matrix.
2
Q
What happens during Krebs Cycle?
A
Pyruvic Acid from glycolysis combines with coenzymes A to form Acetyl CoA which enters the Krebs Cycle.
3
Q
What does each turn of Krebs Cycle produce?
A
Each turn produces 1 molecule of ATP and FADH2 and 3 molecules of NADH.
4
Q
What is the by product of the Krebs Cycle?
A
CO2
5
Q
Summary
A
- Small amount of ATP
- CO2
- NADH and FADH2
6
Q
What are NADH and FADH2?
A
They are coenzymes that shuttle protons during Glycolysis and Krebs Cycle to Electron Transport Chain.
7
Q
What is the oxidized form of NADH?
A
NAD+
8
Q
What is the reduced form of NADH?
A
NADH
9
Q
What is the oxidized form of FADH2?
A
FAD+
10
Q
What is the reduced form of FADH2?
A
FADH2
11
Q
FAD AND NAD carry H+ (protons) from the Krebs Cycle to the Electron Transport Chain.
A
Yes
