Document Summary
Body fluids and compartments: intracellular fluid: watery solution of dissolved substances present in the body (67%, extracellular fluid (33%) Dna: exons are actually code for proteins, slice away introns, translation trna builds protein at ribosomes until it reaches stop codon. Role and types of second messengers: camp, adenylyl cyclase and camp pathway can generate lots of second messengers like camp, calcium. Increases intracellular levels of calcium by opening calcium ion channels in the plasma membrane, releasing calcium from the. Er, and the inhibition of active calcium transport out of the cell. Exergonic vs endergonic reaction: exergonic reactions give off energy, endergonic reactions take in (need) energy, exergonic reactions can drive endergonic reactions and vice-versa. Reversible vs irreversible: reversible: reactants products, can go either way, continues until chemical equilibrium is reached, rate of forward reaction = rate of backward reaction, irreversible: reactions products, only goes one way.
