Question

an important similarity between photosynthesis and cellular respiration is that both processes
use and store o₂.
use and make atp.
store energy in glucose.
release energy from glucose.

Explanation:

• Photosynthesis:
• In the light - dependent reactions, ATP is made (through photophosphorylation).
• In the Calvin cycle (light - independent reactions), ATP is used to convert \(CO_2\) into glucose.
• Cellular Respiration:
• In glycolysis, a small amount of ATP is made (substrate - level phosphorylation).
• In the Krebs cycle, a small amount of ATP is made (substrate - level phosphorylation).
• In oxidative phosphorylation (electron transport chain), a large amount of ATP is made. And ATP is used in some of the preparatory steps (e.g., phosphorylation of glucose in glycolysis).

Answer:

use and make ATP.
