Stage 3: Respiration (Pyruvate Dehydrgenase)

Question 1

respiration includes

Answer 1

pyruvate dehydrogenase pathway, TCA cycle, ETC

Question 2

what is the pyruvate dehydrogenase pathway complex

Answer 2

large, composed of multiple subunits of 3 enzymes and several cofactors

Question 3

step 1 decarboxylation

Answer 3

decarboxylation of pyruvate. produces CO2 as waste

Question 4

step 2 carbon products

Answer 4

carbon products are oxidized and NAD+ is reduced to NADH

Question 5

step 3 2 carbon acetyl

Answer 5

2 carbon acetyl group are linked to CoA producing acetyl~CoA

Question 6

net production

Answer 6

pyruvate + NAD+ + CoA —> CO2 + NADH + acetyl~CoA

Question 7

anabolism

Answer 7

acetyl~CoA can be used to synthesized fatty acids
