BIOL 1201 : BIOL 1201 Exam 2 Notes
Document Summary
Photosynthesis- perhaps the most important reaction in biology . Cq: when a plant grows, the increase in biomass (carbon) comes from. Cq: are there photosynthetic animals: maybe- depends on how you define photosynthetic animals. Photosynethesis: recycles atmospheric co2, approximately 140 to 180x109 tons (dry weight) of carbon are produced, reactions independent of light. Cq: when a plant grows, the increase of biomass (carbon) comes from: the air. Focus: reactiongs of photosynthesis, what is utilized, what is produced, compartment where the reactions occur. Calvin-benson cycle: andy benson and melvin calvin at the university of california- berkley, 1946, nobel prize to melvin calvin 1961, uses atp and nadph from the light reactions to synthesize sugars from co2. The light-dependent reactions produce: reducing power (nadph, atp, o2. Chlorophyll a and chlorophyll b and accessory pigments: absorb light in the visible spectrum. Located in the thylakoid membrane of the chloroplast. Light energy: used by photosystem i and photosystem ii.
