Cells use active transport proteins to
|
|
obtain molecules they need
|
|
|
break down molecules
|
|
|
engulf large particles
|
|
|
detect the charge of molecules

Explanation:
Detailed explanation-1: -Active transport uses energy to transport molecules across the plasma membrane. This uses energy from ATP. They also use pumps to get molecules in or out of the cell.
Detailed explanation-2: -Active transport requires energy for the process by transporting molecules against a concentration or electrochemical gradient.
Detailed explanation-3: -Active transport requires energy. It could be compared to a ball moving up a hill. Active transport is the transport of molecules that require the use of energy, in the form of an energy-storing chemical called ATP (adenosine triphosphate) to help them cross the cell membrane.
