What connection is there between Photosynthesis and Glucose production
attashe74 [19]

Answer:

The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other.

Explanation:

For example, the output of photosynthesis is the input of glucose production or cellular respiration. The output of glucose production is the input of photosynthesis. Photosynthesis involves the use of energy from sunlight, water, and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water.  To emphasize this point, even more, the equation for photosynthesis is the opposite of cellular respiration.
