Document Summary
Mainly occurring in muscle, liver, some in mammary glands (milk proteins being made), proteins being made in and being broken down in every cell of the body. Na+-dependent: more transporters, the faster the transporters will be, dependent on gradient and how many transporters there are, energy expenditure required, atp is used, sodium atpase. Aa counter transport: one aa goes in, one goes out, trades. Things to know: can have acive transport, facilitated difusion, counter transport, redundancy and compeiion is there, consequence of transport being this way. Mrna can be degraded, can get recycled, constant synthesize and degradaion, controls concentraion. Polymerase and enzymes that are involved in that, etc. Exons and introns, only parts of the dna that code for the protein, when irst transcribed the heterogeneous nuclear rna has the whole thing, then get splicing out to get the mrna. Can get diferent splicing: structure of the cell (e. g. cytoskeleton, carrier proteins, etc. ) are being synthesized all the ime.
