Question

question 1-7
which scenario below would most likely cause an increase in adp production?
a plant cell is exposed to high levels of sunlight.
an animal cell is exposed to high levels of oxygen.
a plant cell needs water to catalyze high energy reactions.
an animal cell moves large molecules through the membrane.

Explanation:

To determine which scenario increases ADP production, we analyze each option:

1. Plant cell exposed to high sunlight: This drives photosynthesis, which produces ATP (using ADP + Pi), so ADP would be converted to ATP, not increased.
2. Animal cell exposed to high oxygen: High oxygen supports aerobic respiration, which produces ATP from ADP, so ADP decreases as it is used to make ATP.
3. Plant cell (text partially unclear, likely "uses water"): Water is involved in reactions like photosynthesis or hydrolysis, but water alone doesn’t directly drive ADP production. Photosynthesis uses light energy to make ATP, while hydrolysis of ATP produces ADP, but water alone (without an energy - consuming process) isn't a direct trigger for increased ADP.
4. Animal cell moves large molecules through the membrane: Moving large molecules (like via active transport) requires energy, which comes from ATP hydrolysis (ATP → ADP + Pi). So this process consumes ATP, producing more ADP.

Answer:

An animal cell moves large molecules through the membrane.
