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)...

Correct Answer: prevent cells from replicating. lysogenic cycle Correct Answer: a viral reproductive cycle in which the viral DNA is added to the host cell's DNA and is copied along with the host cell's DNA Lytic phase or lytic cycle Correct Answer: phage replicates immediately, destroying the host cell (All phages carry out this life cycle) prote...

Consider a biochemical reaction A to B, which is catalyzed by A-B dehydrogenase. Which of the following statements is true? A. The reaction will proceed until the enzyme concentration decreases. B. The reaction will be more favorable at 0 degrees C. C. A component of the enzyme transferred from A to B. D. The free energy change (delta G) of the catalyzed reaction is the same as for the uncatalyzed reaction. D. -In an enzyme-catalyzed reaction, the rate of a reaction is increased by a dec...
