Where the glucose in peas come from?

Glucose in peas or any plant comes from the photosynthesis process. Photosynthesis is the metabolic pathway by which plants and other organisms use the energy from sunlight to convert carbon dioxide and water into energy-rich molecules, such as glucose.

In the case of peas, the glucose is synthesized in the leaves of the plant. The leaves are covered in chloroplasts, which are small organelles that contain chlorophyll. Chlorophyll is a pigment that absorbs light energy and uses it to convert carbon dioxide and water into glucose and oxygen.

The chemical equation for photosynthesis is:

6CO2 + 6H2O + light energy → C6H12O6 (glucose) + 6O2

This means that for every six molecules of carbon dioxide and six molecules of water that the plant takes in, it produces one molecule of glucose and six molecules of oxygen.

The glucose produced by photosynthesis is then transported throughout the plant and used as an energy source for growth and development. It can also be stored as starch for later use.
