True or false?
true/false : the conversion of substrate a into substrate b by a specific enzymatic pathway requires that each enzymatic reaction within that pathway has a negative δg.
true/false : in active transport, the transported species moves across the membrane in the thermodynamically favored direction.
true/false : the velocity of the reaction is dependent of the enzyme concentration.
true/false : of the phosphoglycerides phosphatidylserine, phosphatidylcholine, and phosphatidylethanolamine, only phosphatidylserine will have a net negative charge at neutral ph.
true/false : polar, but uncharged, compounds readily diffuse across the bilayer.
true/false : g-protein-coupled receptors rely on 2nd messengers such as ca2+, cyclic gmp, phosphatidylinositol, & cyclic amp to activate/inactivate various pathways in a cell.
true/false : the enzyme velocity is at its maximal rate when all of the substrate molecules in solution are bound by the enzyme.
true/false : the close packing of the tails of the lipids in a membrane is favored by electrostatic interactions between the acyl chains.
