Photosynthesis doesn't directly produce proteins. Instead, it produces glucose, a type of sugar.

Here's how it works:

1. Light-dependent reactions: Sunlight is captured by chlorophyll and used to split water molecules. This process releases oxygen and produces ATP (energy) and NADPH (electron carrier).

2. Light-independent reactions (Calvin Cycle): ATP and NADPH are used to convert carbon dioxide into glucose.

Proteins are made through a different process called protein synthesis, which uses the genetic code stored in DNA to assemble amino acids into chains.

However, the glucose produced during photosynthesis is essential for protein synthesis. It provides the energy and building blocks (carbon atoms) needed to create new proteins.
