Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle releases the energy stored inside food
A
Chloroplast
B
Mitochondria
C
Lysosomes
D
Nucleus
Explanation: 

Detailed explanation-1: -Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.

Detailed explanation-2: -Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. In cellular respiration sugar with the help of oxygen is broken down into ATP (energy molecule).

Detailed explanation-3: -The faster they move, the more energy is stored. It takes energy to get an object moving, and energy is released when an object slows down. Wind is an example of motion energy.

Detailed explanation-4: -At the inner mitochondrial membrane, a high energy electron is passed along an electron transport chain. The energy released pumps hydrogen out of the matrix space. The gradient created by this drives hydrogen back through the membrane, through ATP synthase.

Detailed explanation-5: -The main function of Mitochondria is to convert energy.
