Question

these singla transduction questions

This type ATP ase carries the widest variety of solutes. What would be the expected result if a competitive, nonhydrolyzable analog of ATP were applied to the cytoplasmic side of a plasma membrane that contained a large concentration of the Na+/K+ pump? Which of the following accurately describes the driving force and directionality of the nonactive transport of all molecules across the membrane? Sarin is a toxic substance that irreversibly inhibits the enzyme responsible for degrading acetylcholine (acetylcholinesterase). Which of the following reactions would you expect of an organism poisoned by sarin?

Explanation / Answer

1. ATPase with widest variety of solutesis: ABC-type

2. The cell interior would experience higher than normal Na+ concentration and lower than normal K+? concentration .

3. Deriving force and directionality of nonactive transport of all molecules across the membrane can be accurately described by: The movement toward equilibrium.

4. Continuous muscle spasm and convulusions.
