Question

Which of the following phrases best describe active transport?

Answer 1

Can you post the phrases please?

Answer 2

Hi, may I ask is this the answers choice that you have? If yes then here's my explanation to you:)

A) The movement of substances across a biological membrane down a concentration gradient (i.e, from high concentration to low concentration)
B) The movement of substances across a biological membrane with a membrane potential (i.e., from regions of positive charge to regions of negative charge)
C) The diffusion of water across a semipermeable membrane
D) The movement of substances across a biological membrane up a concentration gradient (i.e., from low concentration to high concentration)
E) None of the above

Ok,
A describes diffusion,
B possibly Electrostatic Induction
C describes osmosis
D is active transport

Active transport is the mediated process of moving particles across a biological membrane against a concentration gradient. If the process uses chemical energy, such as from adenosine triphosphate (ATP), it is termed primary active transport.
