Question

Responses

The chemical equations for the processes are opposite of each other.

The chemical equations for the processes are opposite of each other.

Both processes are carried out in the same location in the cell.

Both processes are carried out in the same location in the cell.

The steps in both processes are very similar to each other.

The steps in both processes are very similar to each other.

Photosynthesis occurs in plants; cellular respiration occurs in animals.

Answer 1

The true statement about photosynthesis and cellular respiration is:

The chemical equations for the processes are opposite of each other.

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration converts glucose and oxygen into carbon dioxide and water, essentially reversing the chemical equations of each process.

The other statements are not accurate:

• Photosynthesis occurs mainly in the chloroplasts of plant cells, while cellular respiration occurs in the mitochondria of both plant and animal cells.
• The steps in both processes are not very similar; they involve different pathways and mechanisms.
• Both plants and animals perform cellular respiration, although only plants perform photosynthesis.
