Here's a brief overview of the steps involved in photosynthesis to help you quickly grasp how the process works. Light is absorbed by chlorophyll, a ferment contained in leaves. Light energy is converted into chemical energy: light energy is used to split a water molecule. The reaction releases chemical energy.
Photosynthesis is a process in which sunlight energy is used to make glucose. The site of photosynthesis is in the chloroplast – an organelle found in the leaves of green plants. The main functions of chloroplasts are to produce food (glucose) during photosynthesis, and to store food energy. Chloroplasts contain the pigment, chlorophyll ...
Embedded in the thylakoid membrane are molecules of chlorophyll, a pigment (a molecule that absorbs light) through which the entire process of photosynthesis begins. Chlorophyll is responsible for the green color of plants.
PHOTOSYNTHESIS: • converts light energy to the chemical energy of food 6CO2 + 6H2O + light energy C6H12O6 + 6O2. Happens in all green parts of plants but leaves = major site ~ about half a million chloroplasts/mm2 of leaf surface. Color of leaf due to green pigment chlorophyll.
Stages of photosynthesis. When chlorophyll a absorbs light energy, an electron gains energy and is 'excited'. The excited electron is transferred to another molecule (called a primary electron acceptor). The chlorophyll molecule is oxidized (loss of electron) and has a positive charge.
