Question

when charlotte got an infection, her temperature rose 2–3°c. her body got the energy needed to react to the infection by... a) decreasing co₂ removal from cells. b) increasing cellular respiration in mitochondria c) stopping photosynthesis in mitochondria d) lowering atp production in ribosomes

Explanation:

• Option A: Decreasing \( \text{CO}_2 \) removal would not provide energy; cells need to get rid of \( \text{CO}_2 \) from respiration, so A is incorrect.
• Option B: Cellular respiration in mitochondria produces ATP (energy) for the cell. During infection, the body needs more energy to fight it, so increasing mitochondrial respiration makes sense.
• Option C: Mitochondria do not perform photosynthesis (photosynthesis occurs in chloroplasts of plants/algae), so C is incorrect.
• Option D: Ribosomes are for protein synthesis, not ATP production (ATP is made in mitochondria), so lowering ATP production in ribosomes is irrelevant and incorrect.

Answer:

B) Increasing cellular respiration in mitochondria
