Glycolysis W1

Question 1

Where does glycolysis occur?

Answer 1

Cytosol

Question 2

How does exercise speed up glycolysis?

Answer 2

Substrate availability
Physiological factors
Cellular Factors
Molecular Factors

Question 3

How does substrate availability benefit from exercise?

Answer 3

Increased glycogenolysis favours glycolysis

Question 4

How does physiological factors benefit from exercise?

Answer 4

Greater blood flow= Increased glucose to active muscles

Question 5

How does cellular factors benefit from exercise?

Answer 5

Increased glucose uptake from transporters (GLUT4)

Question 6

How does molecular factors benefit from exercise?

Answer 6

There is allosteric activation of pyruvate kinase and phosphofructokinase involved in glycolysis

Question 7

What is the primary product of glycolysis?

Answer 7

Pyruvate (3 carbon compound)

Question 8

What is the net gain of ATP in glycolysis?

Answer 8

2 ATP

Question 9

How does glucose get to pyruvate?

Answer 9

1. Glucose 6-phopshate
2. Phosphofructokinase
3. Pyruvate Kinase

Question 10

What happens to ATP, AMP and Phosphocreatine via phosphofructokinase?

Answer 10

ATP= Decrease
Phosphocreatine= Decrease
AMP= Increase

Question 11

What happens to ATP, ADP and Phosphocreatine via Pyruvate Kinase?

Answer 11

ATP= Decrease
Phosphocreatine= Decrease
ADP= Increase
