Lecture 13: ETC

Question 1

What is produced in TCA

Answer 1

3 NADH, 1FADH, 2CO2, 1ATP

Question 2

What is accomplished in the TCA

Answer 2

Carbon source is oxidative down to carbon dioxide and potential energy is transferred to electron carriers and ATP

Question 3

How many ATP is produced in glycolysis

Answer 3

A net of two ATP is produced in glycolysis through substrate level phosphorylation

Question 4

How many electron carriers are produced in glycolysis

Answer 4

Two NADH

Question 5

How many ATP are produced in the synthesis of acetyl co a

Answer 5

None

Question 6

What is the total amount of electron carriers produced in combination of glycolysis and TCA

Answer 6

10 NADH and 2F ADH

Question 7

High energy state of cell will have…

Answer 7

High concentrations of ATP and NADH

-inhibition of respiratory

Question 8

Low energy state of cell

Answer 8

Have high concentrations of ADP AND NAD+

Must stimulate respiratory pathways

Question 9

What are allosteric enzymes

Answer 9

Enzymes that change their shape upon binding to an activator or inhibitor

Question 10

What are the reactants in TCA

Answer 10

Acetyl CoA, NAD, FAD, NAD, Pi
