IMPORTANT ENZYMES FOR MCAT EXAM-39 QUESTIONS AND ANSWERS 2024.

MCAT Chem/PhysGenerally, how are proteins formed? The connecting of a string of amino acids via peptide bonds and the folding of this string to create a completed protein. The folding is determined primarily by the hydrophilic and/or hydrophobic nature of the amino acids. Stabilized by hydrogen bonds, disulfide bridges, and other intramolecular forces. Peptide (Amide) Bonds These are formed when the n-terminus of one amino acid attacks the carboxy terminus of another amino acid. Water is ...

MCAT: Biochemistry Questions and Answers | Latest Update | 2024/2025 | 100% Verified What is the function of chaperone proteins in cellular biology? Chaperone proteins assist in the correct folding of newly synthesized proteins and prevent misfolding or aggregation. Describe the role of ATP in cellular energy transfer. ATP provides energy for cellular processes by releasing a phosphate group through hydrolysis, which drives biochemical reactions. How do allosteric enzymes di...

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...
