Sunlight then enters the leaf and penetrates the mesophyll cells of the leaf. Learn. Because this state of an electron is very unstable, the electron is transferred from one to another molecule creating a chain of redox reactions, called an electron transport chain (ETC). 3.

A pigment molecule in the photosystem absorbs one photon, a quantity or “packet” of light energy, at a time. 1. Gravity. Played 0 times. STUDY. Light-dependent reactions change light energy to chemical energy in the first stage of photosynthesis. Once the electrons were in photosystem I, electrons are energized again. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. Light-Independent Reactions: Light-independent reactions is one of the major parts of the process known as photosynthesis. The reactions create ATP and NAPDH from precursor chemicals and water using energy captured from light by dyes such as chlorophyll. Conceptual overview of light dependent reactions.
