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 AMINO ACIDS QUESTION AND ANSWERS WITH SOLUTIONS 2024

MCAT NephronProximal convoluted tubule (1) - correct answer permeable to amino acids, glucose, water-soluble vitamins, and salts, which are reabsorbed with water. Filtrate is isotonic to interstitium. Vasa recta - correct answer capillary bed that removes substances from interstitium to be returned to systemic circulation Descending loop of Henle(2a) - correct answer Water-permeable; as interstitial concentration increases, water flows out of this structure. Ascending loop of Henle (2b)...
