Document Summary
Indicates possible homology between eyespots and eyes: eye is complex, eyespot is simple, but not primitive. Primitive would mean that the trait is no longer present in organisms today. Post lecture: relationship between pigments and associated protein. 5: pigments are always bound to their associated protein; they are never free, when light is absorbed in a pigment, this results in a photochemical reaction such as a photoisomerization in channelrhodopsin. Thus, blue and red is absorbed really well. Induced expression: protein increases in expression following a change. In heat shock, hsp would increase in abundance due to it being required to combat the heat: repressed expression: protein decreases in expression following a change. Energy required to get to the transition state is called the energy of activation activated molecules. Rate of reactions is proportional to the number of. Enzymes are huge in comparison to the substrate. For some enzymes the catalytic cycle can be very.
