AAMC MCAT Practice Exam 1 Questions and Answers | Latest Version | 2024/2025 | 100% Verified What is the primary function of the mitochondria in a cell? - A) Protein synthesis - B) DNA replication C) ATP production - D) Lipid metabolism Rationale: Mitochondria are known as the "powerhouses" of the cell because they produce ATP through oxidative phosphorylation, which provides energy for various cellular processes. Which of the following best describes the function of enzym...

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...

AAMC MCAT Exam 4 QUESTIONS AND ANSWERS RATED A+ 2023|2024 Most cytochrome P450 enzymes alter the activity of drugs by: A. phosphorylating them. B. dephosphorylating them. C. oxidizing them. D. reducing them. - ANSWER C. oxidizing them. cytochrome p450 acts as monooxygenase, where an oxygen atom is inseted into substrate, thereby resulting in oxidation of substrate. Given that antibiotics like erythromycin are metabolized by estrogen-sensitive P450 enzymes within the liver, which g...

MCAT Practice Questions Why are triacylglycerols used in the human body for energy storage? A) They are highly hydrated, and therefore can store lots of energy. B) They always have short fatty acid chains, for easy access by metabolic enzymes. C) The carbon atoms of the fatty acid chains are highly reduced, and therefore yield more energy upon oxidation. D) Polysaccharides, which would actually be a better energy storage form, would dissolve in the body. - correct answer C Triacylglyce...
