5

Which of the following is false concerning either photosynthesis or respiration:

Group of answer choices

a the cytochromes of the ETS are located within the matrix

b Light harvesting complexes capture photons in the light dependent reaction

c terminal oxidation involves O2 as the final electron acceptor in ETS

d the cyclic electron flow in photosynthesis is used to maintain the correct ratio of NADPH and ATP, using H+ flow to make additional ATP

6

Group of answer choices

a it produces more energy per glucose molecule than does aerobic respiration

b it produces a net gain of ATP

c it is an aerobic process

d is used to regenerate NADH

e will produce ethanol and CO2

Answer 1

1. A typical product of ETS would have NAD+, H2O.

Does not produce- FAD, and CO2.

2. True- a. membrane lipids are in the cis conformation,

False- b. the number of carbons composing the tails is an uneven number, c. proteins are embedded within only one membrane leaflet, d. the lipid bilayer is “fluid” in regard only in regard to the protein composition.

3. Photosystem I is known as P700 because- c. this pigment is best at absorbing light with a wavelength of 700 nm

4. The rate of diffusion for the indicated molecules across a biological membrane going from the fastest rate to slowest rate- Since the plasma membrane supports the uncharged molecules to pass through its barrier, it allows

d. oxygen, glycerol, sodium ion.

5. False concerning either photosynthesis or respiration: d. the cyclic electron flow in photosynthesis is used to maintain the correct ratio of NADPH and ATP, using H+ flow to make additional ATP.

6. True of fermentation: b. it produces a net gain of ATP, d. is used to regenerate NADH, e. will produce ethanol and CO2.
