Document Summary
Modes of regulation: regulation of transcription and translation, Review mechanisms of transcription, translation and replication if necessary, A given cell at a given time could be subjected to a number of different environmental conditions requiring different enzymes, Typically, cells produce the necessary enzyme only under the conditions that require those enzyme, when the second type of nutrients is relevant. Organisms can often differentiate their cells into different cell types under certain conditions, There are levels to where enzyme activities can be turned on and off: regulation of level of transcription (no mrna, regulation of level of translation (mrna, no enzyme, regulation of enzyme activity (mrna, enzyme, but no production. Example demonstrates a pathway that has an end product which started from a starting material and underwent a few enzymatic pathways, At each of the biochemical transformations, there was a distinct enzyme that was involved,
