Mitochondria is the ‘Powerhouse of the cell’.

Concept: The above-given statement is true.

• Because they generate energy in the form of ATP, mitochondria are the powerhouse of the cell (Adenosine Triphosphate). 
• Cellular respiration is what causes it to happen. The mitochondria are the organelles that assist the body's many metabolic processes. The cell organelle that is present in eukaryotic cells is a mitochondrion. 
• It is an organelle with two membranes—an outer membrane and an inner membrane. Peri-mitochondrial space refers to the area between the two membranes. 
• Cristae are a structure made up of the tightly folded inner layer of mitochondria. The cristae will give chemical reactions a bigger surface area to happen on. F-type particles, also known as oxysomes, make up the cristae. 
• Porins, membrane-associated proteins found in the outer membrane, aid in the exchange of chemicals entering the mitochondria from the outside.

Hence, option A is the correct answer.
