Question

which statement describes the reaction for cellular respiration?
the equation is carbon dioxide + water → glucose + oxygen + water and energy is required in the form of light
the equation is glucose + oxygen → carbon dioxide + water and energy is produced in the form of atp.
the equation is carbon dioxide + water → glucose + oxygen + water and energy is produced in the form of atp.
the equation is glucose + oxygen → carbon dioxide + water and energy is required in the form of light.

Explanation:

Cellular respiration is the process where glucose and oxygen are used to produce carbon dioxide, water, and energy in the form of ATP. Photosynthesis (using light energy to make glucose from CO₂ and H₂O) is different. So we analyze each option:

• First option: Wrong equation (photosynthesis - like) and wrong energy source (light, not for respiration).
• Second option: Correct equation (glucose + O₂ → CO₂ + H₂O) and energy as ATP (produced in respiration).
• Third option: Wrong equation (photosynthesis - like, but claims respiration).
• Fourth option: Wrong energy source (light, respiration doesn't need light) and equation is respiration - like but energy description wrong.

Answer:

B. The equation is glucose + oxygen → carbon dioxide + water and energy is produced in the form of ATP.
