(T/F) Acid-base catalysis involving free protons or hydroxide ions is thermodynamically favorable because these are already in high concentrations in the cell. Correct Answer-False (T/F) The glycerophosopholipids of a membrane bilayer have been modified to contain additional double bonds. This change will likely lower the activation of adenylate cyclase by a G-protein. Correct Answer-False (T/F) To be inserted, a α-helical integral membrane protein requires at least one helix that is at l...

Dr Rai biochem test 2 questions & answers 2023/2024 kinetic mechanism - ANSWER-the order of binding of substrates and release of products sequential mechanism - ANSWER-each substrate binds but both substrates must be bound by enzyme to form a ternary complex before catalysis can occur ping pong mechanism (double displacement) - ANSWER-Substrate binds to the enzyme and releases a product before the second substrate binds to the enzyme Random order enzyme mechanism - ANSWER-any react...

Define Km in MM kinetics: - ANSWER-The concentration of substrate [S] at which 1/2 Vmax is reached Km is _________ related to affinity of the enzyme for its substrate - ANSWER-inversely Vmax is directly proportional to what? - ANSWER-to the enzyme concentration What characterizes MM kinetics? - ANSWER-a hyperbolic curve when Vmax is plotted against [S]. Most enzymes follow MM kinetics. Enzymatic reactions demonstrated a sigmoid curve usually denote: - ANSWERcooperative binding / kinetics, ...
