Photosystem I - an overview ScienceDirect Topics
WebbAll organisms produce a phosphate compound, ATP, which is the universal energy currency of life. In photophosphorylation, light energy is used to pump protons across a biological membrane, mediated by flow of electrons through an electron transport chain. This stores energy in a proton gradient. WebbThe light-dependent reactions begin when photosystem I absorbs light. 3. Electrons from water molecules replace the ones lost by photosystem II. 4. ATP is the product of photosystem I. 5. ATP and NADPH are two types of protein carriers. True True photosystem II NADPH energy 013368718X_CH08_115-128.indd 8 1/5/09 12:00:39 PM how drugs act on the body
What are the roles of photosystem I and photosystem II in the …
WebbIn photosystem II (P680), the e- comes from the splitting of water, which releases oxygen as a waste product. In photosystem I (P700), the e- comes from photosystem II via the … WebbPhotosystem I has a reaction centre that possesses chlorophyll-a molecules. It is capable of absorbing light at a wavelength of 700 nm. The light-harvesting or antenna complex of PS I absorbs photons and hand them over to its reaction centre containing chlorophyll-a. The reaction centre excites and releases high energy electrons. how dr removes ear wax
