WebJan 24, 2024 · Light Reaction of Photosynthesis is defined as a series of chemical reactions that require light energy captured by the pigment present in the leaves (such as chlorophyll) to get converted into chemical energy in the form of ATP and NADPH. This reaction is also known as the Photochemical phase or light-dependent reaction. WebSlide 1 The light reactions of photosynthesis Objective of the lecture: 1. To describe the structure of function of chloroplasts. 2. To define the light reactions of photosynthesis. Text book pages: 198-212. Plants use sunlight, carbon dioxide, and water to produce carbohydrate with oxygen as a byproduct.

WebThe “Z‐scheme” describes the oxidation/reduction changes during the light reactions of photosynthesis. The vertical axis in the figure represents the reduction potential of a particular species—the higher the position of a molecular species, the more negative its reduction potential, and the more easily it donates electrons.
