Question 1

Cellular respiration terminal electron acceptor in ETC?

Answer 1

O2

Question 2

Competitive inhibition

Answer 2

Inhibitor binds to the active site (competes with substrate)

Question 3

Non competitive inhibition

Answer 3

Inhibitor binds to allosteric site (cannot be outcompeted bc if bound substrate has limited or no binding to active site)

Question 4

Phosphatase

Answer 4

Enzyme that cleaves phosphate off substrate

Question 5

Protein kinase

Answer 5

Adds phosphate to substrate

Question 6

Innate immune response

Answer 6

Nonspecific

Question 7

Adaptive immune response

Answer 7

Specific

Question 8

Glycolysis products

Answer 8

2 atp, 2 NADH, 2 pyruvate

Question 9

Pyruvate decarboxylation products

Answer 9

2 acetyl coa, CO2, NADH

Question 10

TCA cycle products

Answer 10

For each acetyl coa: 2 CO2, 3 NADH, FADH2, 1 atp

Question 11

Final electron acceptor of alcohol fermentation

Answer 11

Acetaldehyde

Question 12

Answer 13

Lay down myelin sheath on neurons of PNS

Question 14

In a developing zygote, the majority of the cytoplasm comes from…?

Answer 14
