Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When a cell needs energy, I take in nutrients, break them down and supply energy to the cell. I can also convert stored energy in the cell to food. I am a ____
A
Mitochondria
B
Nucleus
C
Cytoplasm
D
Ribosome
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -ATP (Adenosine tri-phosphate) is an important molecule found in all living things. Think of it as the “energy currency” of the cell. 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.

Detailed explanation-3: -cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

Detailed explanation-4: -Answer and Explanation: The cell part that converts food into energy is the mitochondria. The mitochondria is an organelle enclosed by two membranes. The mitochondria hosts the second two steps of aerobic cellular respiration, the citric acid cycle and oxidative phosphorylation.
