Question

Which best describes Active Transport?

A. Using energy, membrane proteins pick up particles and move them with the concentration gradient.
B. Using energy, membrane proteins pick up particles and move them
against the concentration gradient.
C. Using energy, glycoproteins pick up particles and move them against the concentration gradient.
D. Without energy, particles move freely with the concentration gradient.

Answer 1

B, Using energy , membrane proteins pick up particles and move them against the concentration gradient.

Step-by-step explanation:

During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
