MCAT Bio/Biochem Questions and Answers | Latest Version | 2024/2025 | 100% Verified Explain the role of the sodium-potassium pump in maintaining resting membrane potential. The sodium-potassium pump actively transports three sodium ions out of the cell and two potassium ions into the cell, helping to maintain the resting membrane potential by creating an electrochemical gradient. Describe the process of oxidative phosphorylation in cellular respiration. Oxidative phosphorylatio...

E) metal ion. - D) coenzyme. A double-reciprocal plot of 1/V0 versus 1/[S] for an enzyme in the presence of increasing concentrations of an uncompetitive inhibitor will have lines corresponding to the different inhibitor concentrations that are BEST described by which statement? A) The lines will intersect...

Biochem Questions and Answers with Verified Solutions What is the primary structure of a protein? The primary structure of a protein is the linear sequence of amino acids. How do competitive inhibitors affect enzyme activity? Competitive inhibitors decrease enzyme activity by binding to the active site, preventing substrate binding.
