Question 3

Before the citric acid cycle begins, pyruvate is converted to

Answer 3

acetyl CoA

Question 4

In pyruvate oxidation, what is produced?

Answer 4

production of CO2, no ATP

Question 5

The citric acid cycle will generate more ATP via

Answer 5

substrate-level phosphorlyation

Question 6

How is citrate formed?

Answer 6

Acetyl group of acetyl CoA + oxaloacetate

Question 7

What goes to waste in the citric acid cycle ?

Answer 7

2 CO2

(per glucose so * 2 in total)

Question 9

removing a carbon from CO2 from a molecule of pyruvate makes?

Answer 9

acetyl CoA
