Why are photosynthesis and cellular respiration often considered opposites?
Photosynthesis produces twice as many ATP molecules as cellular respiration does.
Water is released during photosynthesis and consumed during cellular respiration
Photosynthesis occurs during the day, and cellular respiration occurs at night.
Oxygen is produced during photosynthesis and used during cellular respiration.

Stomata
Chlorophyll
Thylakoid Membrane
The compound synthesized during photosynthesis is —
H2O
C6H12O6
CO2
O2
In the process of photosynthesis, which pigment has the largest role?

light-dependent.
temperature-dependent.
glucose-driven.
ATP-driven
Which statement best describes the relationship between the products of photosynthesis and the reactants in cellular respiration?
The products of photosynthesis serve as the reactants in cellular respiration to provide chemical energy.
The products of photosynthesis combine with the reactants in cellular respiration to remove ATP from cells.
The products of photosynthesis inhibit the reactants in cellular respiration in the presence of light.
The products of photosynthesis change the structure of the reactants in cellular respiration in the presence of light.
Photosynthesis and cellular respiration both involve the use and release of gases. Which statement correctly identifies the role of gases in the two processes?
Photosynthesis and cellular respiration both use carbon dioxide and release oxygen.
Photosynthesis and cellular respiration both use oxygen and release carbon dioxide.
Cellular respiration uses oxygen and releases carbon dioxide, while photosynthesis uses carbon dioxide and releases oxygen.
Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.
What is the purpose of ATP in both cellular respiration and photosynthesis?
To breakdown glucose to release energy
