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.
