Document Summary

Reasons why chlamydomonas might move towards a light source. to gather information about its surroundings to undergo photosynthesis and produce energy in order to function. Reasons why chlamydomonas might move away from a light source. light becomes harmful if the cell harvests too much and creates ros (reactive oxygen species) which can be mutagenic. Possible mutations that could cause a chlamydomonas cell not to be phototactic. Mutation in channelrhodopsin, may inhibit an action potential preventing the flagella from moving. Mutation of the flagella which may inhibit locomotion: lecture outcomes. Relationship between wavelength and energy content of a photon. energy is inversely proportional to wavelength: shorter wavelength = higher energy, longer wavelength = lower energy. Relationship between pigments and associated protein. pigments are bound to proteins in pigment-protein complexes. When a pigment absorbs a photon of light it may have a consequence on the surrounding protein. Photochemistry: using the excited state to change the structure of a molecule and perform work.
