Unit Review Questions

Question 1

impact of temperature on photosynthesis

Answer 1

bell curve due to enzymes

Question 2

impact of light intensity on photosynthesis

Answer 2

reaches max and levels off due to photon energy boost

Question 3

kinase

Answer 3

phosphorylation

Question 4

isomerase

Answer 4

isomer

Question 5

dehydrogenase

Answer 5

redox

Question 6

differences between aerobic and anaerobic resp (4)

Answer 6

1. O2
2. 36ATP vs 2ATP
3. mitochondria and cytoplasm vs. cytoplasm only
4. critters with/without a mitochondria

Question 7

protein catabolism

Answer 7

1. deamination
2. side chain determines where in repiration the amino acid goes

Question 8

lipid catabolism

Answer 8

1. glycerol is phosphorylated to G3P
2. Fatty acids go through beta oxidation to make acetyl coa

Question 9

Explain the necessity of transferring electrons through the light reaction. Emphasize the necessity of space to concentrate H+

Answer 9

electrons pump H+ into the lumen, which creates an electrochemical gradient. this allows H+ to diffuse through ATP synthase to make ATP vis photophosphorylation

Question 10

reactants of cellular respiration and where it comes from

Answer 10

Glucose - food (mostly carbs)
O2 - atmosphere

Question 11

products of cellular respiration and where it comes from

Answer 11

H2O - H+ and O from ETC
CO2 - from glucose
(Both are exhaled)

Question 12

electrochemical gradient

Answer 12

a transmembrane gradient formed due to the movement of an ion across the membrane.
