OXPHOS

OXPHOS, or oxidative phosphorylation, is a process that cells use to produce energy. It occurs in the mitochondria, the cell's power plants. During this process, molecules like oxygen help convert nutrients from food into a molecule called ATP, which is the main energy source for cell activities. Essentially, OXPHOS captures energy from food and efficiently stores it in ATP so cells can perform functions like movement, growth, and repair. This process is vital for sustaining life and powering the activities of most cells in your body.
