Question

a paramecium is a single - celled organism. which statement best describes the role atp plays in a paramecium?
a atp stores the paramecium’s genetic information.
b atp warns the paramecium of nearby predators.
c atp signals to the paramecium that its environment has changed.
d atp provides energy the paramecium uses to move its cilia.

Explanation:

• Option A: Genetic information is stored in DNA, not ATP. So A is incorrect.
• Option B: ATP is not involved in predator detection or warning. So B is incorrect.
• Option C: ATP is not a signaling molecule for environmental changes. So C is incorrect.
• Option D: ATP is the energy currency of the cell. Paramecia use cilia for movement, and ATP provides the energy for this process. So D is correct.

Answer:

D. ATP provides energy the paramecium uses to move its cilia.
