BM1000 Lecture 7: Lecture 7
Document Summary
Concept of light and dark reactions of photosynthesis. Processes that convert light energy to chemical energy. Nutritional mode of synthesising organic molecules from inorganic materials. Oxidise inorganic substances, such as sulphur, ammonia or hydrogen, as an energy source for synthesising organic molecules. Uses light as an energy source to synthesis organic molecules. Makes energy-rich molecules such as starch and sucrose from energy-poor molecules such as co2 and h2o. Co2 is the carbon source, o2 is a waste- product. Directly or indirectly supplies energy to all heterotrophic organisms. te- y to. In eukaryotic algae, leaves & other green plant organs. We were originally cyanobacteria that entered into an endosymbiotic relationship with eukaryotic cells. Have their own dna , mrna and protein synthesis system (many genes lost to the nucleus, but some kept). The conversion of light energy (photons) to chemical energy (atp and nadph) - with. The use of chemical energy to assimilate co2 from the atmosphere.
