step 3 glycolysis

6

What step of glycolysis is Aldolase present?
A. Isomerization
B. Transfer of a phosphate group
C. Cleavage
D. Oxidation

Cleavage

* if you wear ALDO u get to see CLEAVAGE

7

Which Step in glycolysis helps convert glucose 6 phosphate to fructose 6 phosphate and uses phosphoglucoisomerase?

Isomerization

step 2 is the only isomeraization step to use that enzyme also

8

Glucokinase is present in the________?
A. muscle
B. liver

Liver

9

During phosphorylation in glycolysis, is there a loss or gain of 1 ATP?

loss
*steps 1 and 3 are phosphorylation and use an ATP to run

10

What is another name for phosphoglucoisomerase?

glucosephosphate isomerase

11

During a transfer of a phosphate group in glycolysis steps 7 and 10. Is there a gain or loss of ATP?

Gain

These steps synthesize 1 ATP each

12

The last stage of glycolysis deal with reducing ________ to ________?

pyruvate to lactate

13

During Aerobic activity (with Oxygen), Pyruvate is converted into ___________?

Acetyl CoA

14

During Anaerobic activity, Pyruvate is converted into_________?

Lactate

15

Which Step of glycolysis deal with 2-phosphoglycerate phosphoenolpyruvate + H20?
A. Isomerization
B. Phosphorylation
C. Dehydration
D. Cleavage

Dehydration
