💜 Unit 5: Glucose Catabolism

Question 1

Glucose Catabolism

Answer 1

breaks down glucose to produce ATP

Question 2

What’s another name for Glucose Catabolism?

Answer 2

Cellular Respiration

Question 3

How is energy obtained from catabolism of glucose?

Answer 3

Anaerobic or Aerobic

Question 4

Anaerobic

Answer 4

does NOT require oxygen, occurs in cytosol

Question 5

Aerobic

Answer 5

requires oxygen, occurs in mitochondria

Question 6

Process of Glucose Catabolism

Answer 6

1- Glycolysis
2- Formation of Acetyl Coenzyme
3- Citric Acid Cycle
4- Electron Transport Chain

Question 7

Which of the 4 steps of glucose catabolism are anaerobic and which are aerobic

Answer 7

Aerobic = 2, 3, 4
Anaerobic = 1

Question 8

Process of Glucose Catabolism w/
(oxygen NOT present)

Answer 8

1- Glycolysis
2- Formation of Acetyl Coenzyme
3- Lactic Acid

Question 9

What’s the significance of NAD+?

Answer 9

carries/transfers electrons during glycolysis & citric acid cycle

Question 10

When is NAD+ an electron acceptor?

Answer 10

when it receives electrons and becomes reduced to NADH in glycolysis or citric acid cycle

Question 11

What molecule is an electron donor?

Answer 11

NADH

Question 12

Overall Reaction of Glucose Catabolism

Answer 12

Glucose + 2 ATP+ 6 O2 ——> 6 CO2 +6 H2O + (38 ATP - 2 ATP) = 36 ATP
