Study Notes
Photosynthesis and Cellular Energy Production
- The process of photosynthesis in plant cells involves the absorption of light by three main pigments in the electromagnetic spectrum.
- Light reactions, also known as light-dependent reactions, take place in the thylakoid membranes of chloroplasts and involve a non-cyclic electron pathway.
- The non-cyclic electron pathway includes components such as plastoquinone, cytochrome, plastocyanin, and ferredoxin.
- Light reactions result in the conversion of 12 molecules of water, 12 NADP+, and 18 ADP + 18 Pi, in the presence of light and chlorophyll, into 6 molecules of oxygen, 12 NADPH, and 18 ATP.
- The Calvin cycle, also known as light-independent reactions, involves the RubisCO enzyme and is essential for the conversion of carbon dioxide into organic compounds.
- Different photosynthetic strategies include the C3 strategy, C4 strategy, and CAM strategy, each involving spatial or temporal separation of steps for carbon fixation.
- The information is sourced from "Inquiry into Life, 13th edition" by SS Mader and "Biology Libre Texts".
- Photosynthesis is a crucial process for the production of energy and organic compounds in plant cells.
