BotanyWhich of the following transport across the cell needs ATP and is affected by protein inhibitors?

Which of the following transport across the cell needs ATP and is affected by protein inhibitors?

A
Simple diffusion
B
Facilitated diffusion
C
Active transport
D
Osmosis

Solution:

In facilitated diffusion special proteins help move substances across membranes without expenditure of ATP energy. Facilitated diffusion cannot cause net transport of molecules from a low to a high concentration – this would require input of energy. Active transport used energy usually in the form of ATP for uphill transport.
