Question

What is a major difference between facilitated diffusion and active transport?

Question 3 options:

Active transport moves substances against the concentration gradient.

Active transport uses proteins in the process.

Facilitated diffusion moves molecules through the plasma membrane.

Facilitated diffusion requires large amounts of energy.

Answer 1

The correct option is A. Active transport moves substances against the concentration gradient.

Step-by-step explanation:

Active transport can be described as a transport mechanism in which molecules tend to move against the concentration gradient i.e from an area of lower concentration to an area of higher concentration. Energy is needed for this process to occur.

Facilitated diffusion can be described as a phenomenon is which molecules move along the concentration gradient i.e from a higher concentration to a lower concentration with the help of trans- membrane integral proteins
