Question 17

Which steps in glycolysis use ATP?

Answer 17

Steps 1 and 3

Question 18

Which steps in glycolysis produce ATP?

Answer 18

Step 7 and 10

Question 19

Which steps in glycolysis produce reduced coenzymes?

Answer 19

Step 6

Question 20

What is the fate of pyruvate during anaerobic respiration?

Answer 20

Pyruvate is converted into lactate and produce NAD+ to regenerate for glycolysis

Question 21

What is the fate of pyruvate of aerobic respiration?

Answer 21

Pyruvate is converted into acetyl-SCoA and enters the TCA cycle while producing NADH so that it can be used through respiration
