Mitochondrial function

Definition

Mitochondrial function refers to the processes by which mitochondria produce energy in the form of ATP through cellular respiration. It is crucial for maintaining cellular health and supporting physiological functions, especially in high-energy-demand tissues like the nervous system.

5 Must Know Facts For Your Next Test
