Question

Which of the following transport processes require(s) energy? a)facilitated diffusion b)osmosis c)endocytosis d)facilitated diffusion and osmosis e)facilitated diffusion, osmosis, and endocytosis

Answer 1

Endocytosis and facilitated diffusion require energy, while osmosis does not.

Step-by-step explanation:

The transport processes that require energy are endocytosis and facilitated diffusion. Osmosis does not require energy as it is the passive diffusion of water across a semipermeable membrane. Facilitated diffusion involves the movement of substances from an area of higher to lower concentration using carrier proteins, and endocytosis is the process in which the cell membrane engulfs material, requiring energy in the form of ATP.

Answer 2

The correct option is e) facilitated diffusion, osmosis, and endocytosis.

The transport processes that require energy are:

• Facilitated diffusion: This process requires energy in the form of ATP (adenosine triphosphate) to move molecules across a membrane from an area of higher concentration to an area of lower concentration[1].
• Osmosis: Osmosis also requires energy to move molecules across a membrane, but it does not always require ATP. The energy needed for osmosis can come from either ATP or the concentration gradient itself[1].
• Endocytosis: This process involves the active transport of large molecules, such as proteins, into a cell. It typically requires energy in the form of ATP to power the movement of these molecules across the cell membrane.
