(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...

diffusion controlled limit - Answer The theoretical maximum rate of an enzymatic reaction in solution, about 10^8 to 10^9 M^-1 * s^-1 catalytic perfection - Answer A state achieved by an enzyme that operates at the diffusion-controlled limit. Lineweaver-Burk plot - Answer A rearrangement of the michaelis menton equation that permits the determination of KM and Vmax from a linear plot.

Michaelis-Menten Kinetics Correct Answer [S] = Concentration of substrate V = Velocity Km is inversely related to the affinity of the enzyme for its substrate Vmax = Directly proportion to the enzyme concentration Most enzymatic reactions follow of hyperbolic curve [Michaelis-Menten] kinetics Enzymatic reactions that exhibit a sigmoid curve [Hemoglobin] exhibit positive cooperativity Lineweaver-Burk Correct Answer ↑ y-intercept, ↓ Vmax The further to the right, the x-intercept [Cl...

what is Km - ANSWER-concentration of substrate at 1/2 Vmax what is Km inversely related to - ANSWER-the affinity of the enzyme for its substrate (low Km=high affinity & high Km=low affinity) what is Vmax directly proportional to - ANSWER-enzyme concentration most enzymes follow what kind of kinetics - ANSWER-Michaelis-Menten kinetics (line up and then it flattens out, hyperbolic) if an enzymatic rxn shows a sigmoid curve what does that indicate - ANSWERcooperative kinetics (hemoglobin) do...
