Document Summary
Wed, feb. 6/19 lecture 10: exercises and application of. Cycle 5 lecture 10: exercises and application of concepts i. A cleptoplast - elysia: eats a vaucheria and keeps the chloroplasts in its gut, this means that it can perform photosynthesis. Low redox potential means it is easier to oxidize: higher redox potential means it is easier to reduce. Linear: psii --> psi: cyclic photophosphorylation: only atp is being produced, no water being oxidized, no. Phototransduction vs photosynthesis: the structure of retinal changes, it is not oxidized, when light hits it, the conformational shape changes. Photoisomerization of pigments leading to change in isomeric structure. Light is used to make g3p and other essential molecules, not to acquire information about the information. Absorption of light leads to flow of electrons doesn the etc to produce nadph and atp used in the calvin cycle. Light is used as information about the environment as opposed to making g3p.
