Explanation:

Q1

Cellular respiration breaks down glucose to release energy. Option A is wrong (ATP is produced, not broken down here), C is wrong (cellular respiration consumes oxygen in aerobic type, produces CO₂), D is wrong (photosynthesis produces glucose). So correct is B.

During cellular respiration, ATP (adenosine triphosphate) is the energy molecule produced. ADP is a precursor, NAD+ and FAD are electron carriers. The diagram also shows ATP structure with energy - rich bonds. So correct is C.

The formula for cellular respiration is \( \ce{C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP} \) (energy). Option D matches this: glucose and oxygen react to form carbon dioxide, water, and ATP. A, B, C have incorrect reactants/products order or components.

Answer:

B. Breaks down glucose
