Citric Acid Cycle

Question 1

What is the pyruvate oxidation pathway?

Answer 1

Pyruvate&raquo_space;> decarboxylation&raquo_space;> oxidation&raquo_space;> transfer to Coa&raquo_space;> Acetyl CoA

Question 2

Citric acid cycle only metabolic carbon input is acetyl coa TF

Answer 2

True

Question 3

Citric acid cycle involves multiple low-energy compounds as inputs. TF

Answer 3

False: just acetyl co-a

Question 4

Which outcomes could be said to be a main reason for a cell’s use of the citric acid cycle?

Answer 4

To prevent equilibrium

Question 5

CItric acid cycle involves a single rossman-fold faimly protein as an enzyme. TF

Answer 5

True: NAD+

Question 6

WHich of the citric acid cycle intermediates are involved in a redox reaction involving one of its internal carbons?

Answer 6

Isocitrate

Question 7

Citric acid cycle only metabolic-carbon output is carbon dioxide: TF

Answer 7

True

Question 8

What are the inputs of the citric acid cycle?

Answer 8

Acetyl coa, NAD+, FAD, GDP

Question 9

What are the outputs of the citric acid cycle?

Answer 9

2 CO2, 1GTP, 8 electrons, NADH(high energy), FADH2 (hight energy), ATP

Question 10

Citric acid cycle is so named because:

Answer 10

Of citrate and carboxylic acid.

Question 11

How much a cell runs the citric acid cycle is dependent upon the availability of NAD+ regenerated by doing the electron transport chain. TF

Answer 11

True.

Question 12

Which of the following is a metabolic carbon product of the citric acid cycle?

Answer 12

Carbon Dioxide

Question 13

The fact that thioester bonds are high energy is seen in:

Answer 13

Hydrolysis of succinyl coa

Question 14

What are the main reasons for the cell’s use of the citric acid cycle?

Answer 14

Produce CO2 to avoid equilibrium
Make cell energy currency directly
Reduce high energy nucleotide electron carriers to later produce ATP
Completion of the oxidation of metabolic carbon no matter the fuel source.
