Photosynthesis is the method that plants use to make their own food.
Photosynthesis is the procedure all plants go through to make food.
In Photosynthesis, photons of light are absorbed by chlorophyll molecules, causing them to donate a high-energy electron that is put to work making NADPH and pumping protons to produce ATP. In this section of the lab you will examine recent evidence that proteins embedded in the thylakoid membranes within the chloroplasts of photosynthetic organisms are acting as an antenna to facilitate light capture.
Enzymes involved in photosynthesis and respiration - …
The fundamental principle of photosynthesis is that plants open and close the stomata (pores) on the leaves, and thus control the amount of carbon dioxide and oxygen that passes through them.

Enzymes are presented in the plants cells and the energy for the first
stages in the synthesis comes from sunlight, this is called
Lab 10 - Enzymes and Photosynthesis.
These depend on the frequency and the intensity with which the stomata of the plants open and close, the amount of transpiration (evaporation of water from the stomata) that occurs, the amount of sunlight and heat that the plant is subjected to and the ratio of carbon dioxide consumed by the plant to the amount of water lost through transpiration (this figure is known as the Water Use Efficiency ratio).
Enzyme Activity in Photosynthesis | Synonym
Most enzymes work fastest in neutral conditions. Making the solution more acidic or alkaline will slow the reaction down. At extremes of pH the reaction will stop altogether. Some enzymes, such as those used in digestion, are adapted to work faster in unusual pH conditions and may have an optimum pH of 2 (very acidic) if they act in the stomach.
Some organisms employ even more radical variants of photosynthesis
Enzymes will work best if there is plenty of substrate available. As the concentration of the substrate increases, so does the enzyme activity. However, the enzyme activity does not increase without end. This is because the enzyme can't work any faster even though there is plenty of substrate available.
