1
Q

Why is step 1 important, what is it?

A

It is irreversible - glucose to G-6-P via hexokinase enzyme.

2
Q

Why is step 3 important, what is it?

A

F-6-P to F-1,6-BisP
Catalysed by phosphofructokinase-1 (PFK-1)

Irreversible and first committed step and F-1,6-BisP ONLY used in glycolysis

3
Q

Why is step 6 important, what is it?

A

G-3-P to 1,3-BisPG - makes 2NADH

Catalysed by phosphoglycerate kinase

4
Q

Why is step 6 important, what is it?

A

G-3-P to 1,3-BisPG - makes 2NADH

Catalysed by glyceraldehyde 3-phosphate dehydrogenase

5
Q

Why is step 7 important, what is it?

A

1,3-BisPG to 3PG, 2ATP produced

Catalysed by phosphoglycerate kinase

6
Q

Why is step 10 important, what is it?

A

PEP to pyruvate, 2ATP produced

Catalysed by pyruvate kinase
