Question

which chemical reaction represents the matter and energy conversions that occur during cellular respiration?
a. glucose + co₂→energy + o₂ + water
b. sugar + o₂→atp + co₂ + water
c. energy + water + co₂→sugar + o₂
d. sunlight + co₂→glucose + o₂

Explanation:

Cellular respiration is the process by which cells break down sugar (glucose) in the presence of oxygen to produce ATP (energy - currency of the cell), carbon dioxide, and water. Option A has the wrong reactants and products. Option C represents photosynthesis in reverse. Option D is the equation for photosynthesis.

Answer:

B. Sugar + O₂ → ATP + CO₂ + Water
