Question

Movement of ions or molecules against the
electrochemical gradient is called
(a) diffusion
(b) pinocytosis
(c) Brownian movement
(d) active transport

Answer 1

Answer:Moving Against a Gradient

Active transport mechanisms, collectively called pumps, work against electrochemical gradients. ... Primary active transport moves ions across a membrane and creates a difference in charge across that membrane, which is directly dependent on ATP.

Explanation:

Answer 2

Movement of ions or molecules against the

Movement of ions or molecules against thean electrochemical gradient is called active transport.

• (d) active transport is the correct option.

• A cell is compelled to use energy when the movement of ions is against an electrochemical gradient and this movement is known as active transport.

• The mechanism of Active transport is to consume energy for maintaining the right concentrations of ions and molecules in the cells of a living organism.

• The electrochemical gradients are mainly arranged by primary active transport for storing energy which is released as the ions for moving back down their gradients.

• Secondary active transport expends the energy which is stored in these gradients for moving other ions or molecules against their own gradients.
