Mcat metabolism - Study guides, Class notes & Summaries

MCAT AAMC | Latest Update | 2024/2025 | Graded A+ What is the primary role of the liver in glucose metabolism? The liver regulates blood glucose levels by storing glucose as glycogen and releasing it as needed. This helps maintain stable blood sugar levels throughout the day. How does a competitive inhibitor affect enzyme activity? A competitive inhibitor binds to the active site of an enzyme, competing with the substrate. This reduces the enzyme's ability to catalyze the rea...

MCAT Hormones Questions and Answers | Latest Update | 2024/2025 | Graded A+ What hormone regulates the body's metabolic rate? Thyroxine (T4) regulates the body's metabolic rate. Which hormone is primarily responsible for increasing blood glucose levels? Glucagon is primarily responsible for increasing blood glucose levels. What is the role of insulin in glucose metabolism? Insulin facilitates the uptake of glucose by cells, lowering blood glucose levels. Which gland pr...

MCAT Biology 1.3 Questions and Answers | Latest Update | 2024/2025 | 100% Verified What is the primary function of the rough endoplasmic reticulum? The rough endoplasmic reticulum is involved in the synthesis and modification of proteins, as it is studded with ribosomes that translate mRNA into polypeptides. How do phagocytes contribute to the immune response? Phagocytes, such as macrophages and neutrophils, engulf and digest pathogens and debris, helping to eliminate infection...

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...
