Glycolysis

What number are the 3 irreversible committed steps in glycolysis? 

1, 3, and 10

What is the enzyme for reaction 1 of glycolysis? 

hexokinase

Full name for G6P.

glucose-6-phosphate

Abbreviated name for glucose-6-phosphate.

G6P

Full name for F6P

fructose-6-phosphateA

Abbreviated name for fructose-6-phosphate

F6P

What is the enzyme in reaction 3? 

phosphofructokinase

Full name for FBP.

fructose-1,6-bisphosphate

Abbreviated name for fructose-1,6-bisphosphate

FBP

What does FBP turn into?

dihydroxyacetone phosphate and glyceraldehyde-3-phosphate

Full name for DHAP

dihydroxyacetone phosphate

Abbreviated name for dihydroxyacetone phosphate.

DHAP

Full name for GAP.

glyceraldehyde-3-phosphate

Abbreviated name for glyceraldehyde-3-phosphate

GAP

Between GAP and DHAP, which isomer must be present for the continuation of glycolysis past this point? 

GAP

The first half of glycolysis is called the energy investment stage, why is that?

ATP is used in order to do committed steps, so the body is investing energy

Full name for 1,3-BPG

1,3-bisphosphoglycerate

Abbreviated name for 1,3-bisphosphoglycerate.

1,3-BPG

Full name for 3PG

3-phosphoglycerate

Abbreviated name for 3-phosphoglycerate

3PG

Full name for 2PG

2-phosphoglycerate

Abbreviated name for 2-phosphoglycerate

2PG

Full name for PEP

phosphoenolpyruvate

Abbreviated name for phosphoenolpyruvate

PEP

What is the enzyme in reaction 10?

pyruvate kinase

During which steps in the energy recovery phase is ATP generated?

7, 10

Only two ATP are generated in the energy recovery phase, so why is this phase called that if it makes the same amount of ATP used in the energy investment stage? 

Energy recovery phase happens twice since you will have two GAP molecules, so you really make 4 ATP per glucose 

Which reaction makes water in energy recovery?

9

Which reaction reduces an NAD+?

6
