Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
True or False:In ACTIVE TRANSPORT, energy is not required.
A
True
B
False
Explanation: 

Detailed explanation-1: -Answer and Explanation: This statement is false. Passive transport does not require energy, and active transport does.

Detailed explanation-2: -Active transport requires energy for the process by transporting molecules against a concentration or electrochemical gradient.

Detailed explanation-3: -During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP).

Detailed explanation-4: -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.

Detailed explanation-5: -Answer and Explanation: In active transport, some solutes are moved against their concentration gradients, from one side of a membrane to the other, using energy from ATP hydrolysis. This statement is true.
