List the main results of photosynthesis.

Photosynthesis is divided into two phases: light and dark. In the light phase, ATP, NADP × H2, oxygen as a by-product, and hydrogen protons are formed. In dark glucose, carbon dioxide is reduced to glucose, which, after transformations, becomes an energy reserve and is stored in the form of starch. Those. the products of the dark phase are carbohydrates, nucleic acids, and amino acids.
As a result: several billions of organic matter and free oxygen are produced for breathing.
