During photosynthesis, what is produced?

During photosynthesis, what is produced?

• A. Proteins
• B. Sugars and oxygen
• C. Amino acids
• D. Nitrogen gas

Answer: (B)

Photosynthesis converts light energy into chemical energy stored as sugars, while releasing oxygen as a byproduct. In the light-dependent reactions, water is split to produce oxygen gas and energy carriers (ATP and NADPH). The Calvin cycle then uses carbon dioxide to synthesize sugars like glucose, which the plant can use for energy and growth. So the immediate outputs are sugars and oxygen. Proteins and amino acids come from later metabolic steps that use these sugars and available nitrogen, not directly from photosynthesis, and nitrogen gas is not produced by this process.
