Which organelle is known as the powerhouse of the cell?

The mitochondria are often referred to as the powerhouse of the cell because they are primarily responsible for producing energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration. This energy is essential for powering various cellular processes and functions, from muscle contractions to the synthesis of biomolecules. Mitochondria contain their own DNA and have a unique double membrane structure that facilitates the efficient conversion of nutrients into usable energy. This capability makes them crucial for maintaining the energy balance within cells, allowing them to perform their necessary functions effectively. Understanding the role of mitochondria highlights their importance in energy metabolism and overall cellular health.
