Question

What is the main difference between active transporters and ion channels. Include ideas about the use of energy and the direction of iron movements relative to concentration gradients

Answer 1

Answer

Active transport is the transport of molecules across the cell membrane via protein carriers. Following characteristics are of active transport.

1) ions move against concentration gradient

2) it utilizes energy to transport molecules

3) it occurs via transport protein csrriers

Ions Channels are proteinecious channels having variable pore size present across the cell Membrane having function to transport molecules. Following are the characteristics of Ion channels

1) molecules move along the concentration gradient

2) It doesn't utilise energy to transport molecules

3) Carrier proteins are not required

4)it occurs through pores lined by proteins
