ATP in sugar transport is mainly needed for what?
a) to generate a proton gradient to allow co-transport of a sugar across a membrane
b) to cleave larger sugar molecules into shorter ones for easier transport
c) to allow respiration in mitochondria which is critical for sugar distribution in
all living organisms
d) ATP accumulates in the apoplast and generates a chemical gradient that
allows ATP/sugar co-transport
e) Sugar transport is actually energy independent and does not require ATP at
any step.
Ans: a) to generate a proton gradient to allow co-transport of a sugar across a membrane
