Question

where do photosynthetic organisms get the energy needed to make glucose molecules?

• mitochondria utilize the solar energy manufactured in the chloroplasts to make glucose molecules.
• mitochondria capture solar energy and convert it to the atp and nadph that are used to make glucose molecules.
• chloroplasts capture solar energy and convert it to the atp and nadph that are used to make glucose molecules.
• chloroplasts utilize the solar energy manufactured in the mitochondria to make glucose molecules.

Explanation:

1. Recall the roles of chloroplasts and mitochondria in photosynthesis and respiration: Chloroplasts are the site of photosynthesis, where solar energy is captured and converted into chemical energy (ATP, NADPH) to make glucose. Mitochondria are for cellular respiration (using glucose to make ATP), not capturing solar energy for photosynthesis.
2. Analyze each option:

• First option: Mitochondria don't use solar energy from chloroplasts to make glucose (mitochondria break down glucose). Eliminate.
• Second option: Mitochondria don't capture solar energy (chloroplasts do). Eliminate.
• Third option: Chloroplasts capture solar energy, convert it to ATP/NADPH (used in Calvin cycle to make glucose). Correct.
• Fourth option: Mitochondria don't manufacture solar energy, and chloroplasts don't use energy from mitochondria to make glucose. Eliminate.

Answer:

Chloroplasts capture solar energy and convert it to the ATP and NADPH that are used to make glucose molecules.
