anabolism

Question 3

Glycolysis:

whats the net gains?

Answer 3

• 1 glucose to 2 molecules of pyruvate
• 2 ATP via substrate level phosphorylation
• 2 NADH

Question 4

TCA: whats the net gains?

Answer 4

• pyruvic acid completely oxidized to water and CO2
• 2 ATP
• 6 NADH
• 2 FADH2

Question 5

What is the final electron acceptor in the ETC?

Answer 5

oxygen

Question 6

chemoiosmotic theory?

Answer 6

ATP is synthesized as result of proton motive force generated by passing electrons along chain

Question 7

oxidative phosphorylation?

Answer 7

the use of the reducing power of NADH, FADH2 to synthesize ATP

Question 8

Aerobic respiration

Answer 8

the process of transferring electrons from NADH and FADH2 to oxygen

Question 9

In the absence of O2 if electrons are transferred to an inorganic terminal electron acceptor, such as sulfur, this process is known as

Answer 9

anaerobic respiration

Question 10

In the absence of O2 if electrons are transferred to organic terminal electron acceptor this process is known as
