Question

use the drawing below to answer the question.
paramecium drawing of paramecium
which statement best describes a direct role of atp in a paramecium?
○ atp provides the energy to move cilia.
○ atp stores the genetic code for replication.
○ atp signals the presence of other nearby organisms.
○ atp senses changes in the surrounding aquatic environment.

Explanation:

• ATP is the energy - currency of the cell. In a paramecium, the cilia are used for movement. For the cilia to move, energy is required, and ATP provides this energy.
• The genetic code is stored in DNA, not ATP, so the option “ATP stores the genetic code for replication” is incorrect.
• ATP is not involved in sensing changes in the environment or signaling the presence of other organisms; those functions are carried out by other cellular components and mechanisms, so the options “ATP signals the presence of other nearby organisms” and “ATP senses changes in the surrounding aquatic environment” are also incorrect.

Answer:

A. ATP provides the energy to move cilia.
