Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What organelle breaks down glucose to release energy for the cell?
A
nucleus
B
lysosomes
C
mitochondria
D
vacuole
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: -Glycolysis is the process by which glucose is broken down within the cytoplasm of a cell to form pyruvate. Under aerobic conditions, pyruvate can diffuse into mitochondria, where it enters the citric acid cycle and generates reducing equivalents in the form of NADH and FADH2.

Detailed explanation-4: -Our mitochondria take our glucose molecules through a process called cellular respiration which is essentially just a process of breaking down and converting glucose by combining oxygen with a glucose molecule.
