Question 1

What is oxidative phosphorylation?

Answer 1

the oxidation of an e- donor and reduction of an e- acceptor through the use of the ETC to generate ATP

Question 2

Can eukarya respirate aerobically and anaeobically?

Answer 2

no only aerobically

Question 3

How is nitrate reduced to become nitrogen gas so nitrogen fixers can fix it to ammonium?

Answer 3

Through dissimilatory denitrification (nitrate reduction): nitrate -> nitrite -> nitric oxide -> nitrous oxide -> nitrogen gas

Question 4

Give an example of a photoautotrophic bacterium?

Answer 4

cyanobacterium - blue/green algae

Question 5

Describe glycolysis in 2 phases.

Answer 5

1) Activitation phase
- uses 2 ATP to phosphorylate glucose into fructose 1,6 bisphosphate which is broken down to 2 G3P
2) Energy payoff phase
- G3P generates 4 ATP, 2 NADH, and 2 pyruvates
