Question

The sodium–potassium atpase hydrolyzes atp to pump two k+ ions inside the cell and three na+ ions out. This is an example of energy conversion in which the energy from atp is converted to choose one or more:

a. An action potential.
b. Reorganization of cellular organelles.
c. A chemical gradient across the cell membrane.
d. Movement of the organism.
e. An electrical potential across the cell membrane.

Answer 1

The sodium–potassium atpase hydrolyzes atp to pump two k+ ions inside the cell and three na+ ions out. This is an example of energy conversion in which the energy from atp is converted to,

a. An action potential (the atp derives the ion channels to actively transport ions in and out of the cell)

c. A chemical gradient across the cell membrane. (active transport)

e. An electrical potential across the cell membrane.(The movement of ions across the cell creates a membrane potential. This movement takes place through active transport by the hydrolysis of atp)
