Hill reaction in photosynthesis

WebThis is now called the Hill reaction. It is the main event in light reactions of photosynthesis. The function of light reactions is two fold — (1) The photochemical splitting of water provides hydrogen atoms for the reduction of CO 2, and (2) Producing of ATP which provides energy for the subsequent synthesis of carbohydrates. WebThe equation below represents the photosynthesis reaction: The purpose of this experiment is to test whether factors such as light intensity and level of Carbon dioxide, will affect the rate of photosynthesis, which are the two most important variables in the photosynthesis process. This was demonstrated by Robert Hill in 1938, known as “The ...
