Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
This is the “powerhouse” of the cell. Most of an eukaryotic cell’s energy is made here.
A
mitochondria
B
ribosomes
C
chloroplasts
D
nucleus
Explanation: 

Detailed explanation-1: -Mitochondria (singular, mitochondrion) are often called the powerhouses or energy factories of the cell. Their job is to make a steady supply of adenosine triphosphate (ATP), the cell’s main energy-carrying molecule.

Detailed explanation-2: -Mitochondria-often called the powerhouses of the cell-enable eukaryotes to make more efficient use of food sources than their prokaryotic counterparts. That’s because these organelles greatly expand the amount of membrane used for energy-generating electron transport chains.

Detailed explanation-3: -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-4: -Mitochondria Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Detailed explanation-5: -The proteins synthesized by the proteins in mitochondria are utilized to generate adenosine triphosphate (ATP) from the food. This ATP acts as the energy currency of the cell, because of which the whole cell and body get energy. Thus, mitochondria are called the powerhouse of the cells.
