Question

what is the equation for cellular respiration?
sugar (glucose) + carbon dioxide → water + oxygen + atp
carbon dioxide + water + sunlight → sugar (glucose) + oxygen
carbon dioxide + oxygen + sunlight → sugar (glucose) + water
sugar (glucose) + oxygen → carbon dioxide + water + atp
what is the process by which light energy is converted to chemical energy; produces sugar and oxygen from carbon dioxide and water?
your answer

Explanation:

First Question (Multiple Choice)

To determine the equation for cellular respiration, recall that cellular respiration uses glucose (sugar) and oxygen to produce carbon dioxide, water, and ATP (energy). Let's analyze each option:

• First option: Incorrect, as cellular respiration does not use carbon dioxide as a reactant.
• Second option: This is the equation for photosynthesis, not cellular respiration.
• Third option: Incorrect, as it misrepresents the reactants and products of both respiration and photosynthesis.
• Fourth option: Correct, as it shows glucose and oxygen as reactants, and carbon dioxide, water, and ATP as products, which matches the cellular respiration process.

The process that converts light energy to chemical energy, producing sugar (glucose) and oxygen from carbon dioxide and water, is photosynthesis. This process occurs in plants (and some other organisms) in the chloroplasts, where light energy is captured and used to synthesize glucose.

Answer:

D. sugar (glucose) + oxygen → carbon dioxide + water + ATP
