Which molecule is a product of photosynthesis?

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose. This process primarily occurs in the chloroplasts of plant cells and involves the conversion of carbon dioxide and water into glucose and oxygen, using sunlight as an energy source.

The primary product of photosynthesis is glucose, a simple sugar that serves as an important source of energy for the plant and for organisms that consume the plant. The overall equation for photosynthesis can be summarized as:

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂

Here, carbon dioxide and water react in the presence of sunlight to produce glucose and oxygen. This highlights why glucose is identified as a product of photosynthesis.

In contrast, the other options listed do not directly result from the photosynthetic process itself. Carbon dioxide is a reactant in the process, rather than a product. Amino acids and fatty acids can be synthesized in plants from glucose and other substrates but are not directly produced during photosynthesis. Therefore, glucose stands out as the correct answer to the question about the products of photosynthesis.
