Which of the following processes draws energy directly from the hydrolysis of ATP?

simple diffusion

facilitated diffusion

primary active transport

secondary active transport

Solutions

Expert Solution

Option C-Primary Active transport.

Simple diffusion and Facilitated diffusion are passive transports in which ATP is not used.

Simple diffusion-diffusion of substances through a membrane without requiring any help from other substances.

Facilitated Diffusion-Requires helps of Tranmembrane Proteins For Transport(But not ATP)

primary active transport & secondary active transport requires energy for the Transport of substances(Active Transport)

Primary active transport- processes draws energy directly from the hydrolysis of ATP.For Example-Na+−K+ pump driven by ATP hydrolysis

Secondary active transport- transport of molecules across the cell membrane utilizing energy in forms other than ATP-By using an Symport or Antiport

(Symport- 2 compounds move simultaneously across a membrane in same direction

Antiport-2 compounds move simultaneously across a membrane in opposite direction)

.For example Transport of Glucose in PCT(SGLUT transporters move glucose, along with 2 Na +ions )
