Carbohydrates (Section 2)

Question 1

In Aerobic Metabolism, Pyruvate Dehdrogenase produces what as a substrate for the Kreb’s Cycle?

Answer 1

Acetyl CoA

Question 2

In Anaerobic Metabolism, what is the primary substrate and what does it require?

Answer 2

Lactate (requires NADH for glycolytic pathways)

Question 3

What 4 vitamins are required in PDC?

Answer 3

Thiamen (B1)
Riboflavin (B2)
Niacin (B3)
Pantothenic Acid (B5)

Question 4

Anaerobic Metabolism relies on ____ production?

Answer 4

Lactate Production

Question 5

How many ATP’s formed per NADH through the Electron Transport System?

Answer 5

3

Question 6

In the Electron Transport System, what complex does NADH enter?

Answer 6

Complex 1

Question 7

In the Electron Transport System, what complex does FADH2 enter?

Answer 7

Complex 2

Question 8

Which macronutrients can be metabolized in the KREB’s Cycle?

Answer 8

CHO, Lipids, Proteins

Question 9

In Glycolysis, 2 NADH equates to how much ATP?

Answer 9

6 ATP

Question 10

In Glycolysis, what is the total ATP yield?

Answer 10

2 ATP + 2 NADH (= 6 ATP) = 8 ATP

Question 11

1 glucose molecule yields how much ATP (exclusively) through KREBS?

Answer 11

1 Glucose > 2 Pyruvate > 12 ATP ea = 24 ATP from ETC

Question 12

What is the total ATP yield from KREBS?

Answer 12

8 ATP (Glycolysis) + 6ATP (Pyruvate NADH’s) + 24 ATP (ETC x2) = 38 ATP

Question 13

Of the 12 ATP yielded from one pyruvate molecule going through KREBS, what substrates do the 12 ATP generate from?

Answer 13

x3 NADH (9 ATP)
1 FADH2 (2ATP
1 GTP (1ATP)

= 12 ATP per Acetyl CoA input

Question 14

In Glycolysis, how many ATP’s are used, and how many are created & from what substrates?

Answer 14

4 ATP’s produced (phosphorylation)
2 ATP’s used to generate energy

= net 2 ATP’s

+ x2 NADH’s (6 ATP’s)

6+2 = 8 ATP Yield
