Question

Cellular respiration is related to _____ as______ is to chloroplasts.

• A. nucleus; cytoplasm
• B. mitochondria; photosynthesis
• C. ATP; light
• D. grana; cristae

Answer 1

The correct option is B

mitochondria; photosynthesis

The correct option is B

Explanation of the correct option:

1. Cellular respiration is the process of oxidation of food molecules, like glucose, to carbon dioxide and water with the release of energy in the form of ATP.
2. The process occurs in mitochondria.
3. C₆H₁₂O₆ + 6O₂ $\to$ 6CO₂ + 6H₂O + ATP ( Energy)
4. During the process of photosynthesis, cells use carbon dioxide and energy from the sun to make sugar (carbohydrate) molecules and oxygen.
5. This happens in the chloroplasts.
6. 6CO₂ + 12H₂O $\stackrel{\mathrm{light}}{\to }$ C₆H₁₂O₆ + 6O₂ + 6H₂O

Final answer: Cellular respiration is related to mitochondria as; photosynthesis is to chloroplasts.
