Nature of photosynthesis: Which description best characterizes photosynthesis? Consider energy flow and metabolic type; mention redox as context. Choose the correct statement.

Difficulty: Easy

An anabolic, endergonic (light-driven) process that reduces CO₂ to carbohydrates in chloroplasts
A catabolic, exergonic breakdown of glucose to release energy
A purely physical process with no redox changes
An anaerobic fermentation that produces ethanol or lactate

Correct Answer: An anabolic, endergonic (light-driven) process that reduces CO₂ to carbohydrates in chloroplasts

Explanation:

Concept / Approach
Photosynthesis uses light energy (endergonic) to reduce CO₂ to sugars, building complex molecules (anabolism) while oxidizing water and releasing O₂.

Contrast
Respiration is catabolic/exergonic; fermentation is anaerobic metabolism, not photosynthesis.

Final Answer
An anabolic, endergonic, chloroplast-based process.
