Study Notes
Chlorophyll in Photosynthesis
Structure and Function
- Chlorophyll is a green pigment found in plants, algae, and cyanobacteria
- It plays a crucial role in photosynthesis, absorbing light energy to fuel the process
- Chlorophyll molecules have a magnesium ion at their center, surrounded by a porphyrin ring
Types of Chlorophyll
- Chlorophyll a: the most important form, absorbs light energy and transfers it to other molecules
- Chlorophyll b: absorbs light energy and transfers it to chlorophyll a
- Chlorophyll c: found in some algae and cyanobacteria, absorbs light energy and transfers it to chlorophyll a
Light Absorption
- Chlorophyll a absorbs light in the blue and red parts of the visible spectrum (430 nm and 660 nm)
- This energy is used to fuel the conversion of CO2 and H2O into glucose and O2
Role in Photosynthesis
- Chlorophyll is embedded in the thylakoid membranes of chloroplasts
- It absorbs light energy and transfers it to a special molecule called an electron acceptor
- This energy is used to generate ATP and NADPH, essential for the Calvin cycle
