Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which energy transformation occurs during active transport?
A
chemical energy
B
light energy
C
kinetic energy
D
mechanical energy
Explanation: 

Detailed explanation-1: -If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell.

Detailed explanation-2: -Mechanical energy is produced by sourcing potential and kinetic energy and turning it into power. Examples of this would be steam, water, wind, gas, or liquid fuels that power turbines. Machines are often used to generate other forms of energy through conversion before being used as power.

Detailed explanation-3: -A combustion engine converts the chemical energy of its fuel into heat and then performs useful work. In contrast, motor proteins are molecules that can convert the chemical energy released from adenosine triphosphate (ATP) hydrolysis directly into useful mechanical work.
