There are two different types of cell transportation. Which of the following requires energy? a. Facilitated Diffusion

b. Active Transport

c. Osmosis

d. Simple Diffusion

please help :))

The type of cellular transport that requires energy is active transport (option b).

Explanation:

Active transport —unlike passive transport— involves the passage of molecules or substances through the membrane against a concentration gradient, a process that requires the use of energy.

In the case of active transport the energy for the process comes from the ATP molecule and the mechanism for this to be possible is by means of an ATPase incorporated into the transporter.

The transport of glucose and the sodium-potassium and calcium pumps are examples of this type of transport.

    The other options are not correct because simple diffusion, facilitated diffusion and osmosis are passive transport mechanisms that do not require the use of energy.
