QUESTION:
Which of the following processes includes all others?
a. osmosis
b. diffusion of a solute across a membrane
c. facilitated diffusion
d. passive transport
e. transport of an ion down its electrochemical gradient
ANSWER:Step 1 of 2
Passive transport refers to the process of substance diffusion across a biological membrane, which does not require energy expenditure by the cell.
The concentration gradient, which signifies potential energy, serves as the driving force for this diffusion. In the absence of external forces, a substance naturally diffuses from areas of higher concentration to areas of lower concentration.
