Final answer:
In cellular respiration, the high energy electrons from glucose are used to convert ADP to ATP through oxidative phosphorylation in the mitochondria.
Step-by-step explanation:
In cellular respiration, the high energy electrons from glucose are used to convert ADP to ATP through a process called oxidative phosphorylation. This process occurs in the mitochondria and involves an electron transport chain and ATP synthase.
The electron transport chain consists of a series of proteins that pass high energy electrons from glucose through redox reactions. As the electrons move down the chain, energy is released and used to pump hydrogen ions across the inner mitochondrial membrane. This creates a concentration gradient, and the movement of hydrogen ions back through ATP synthase generates the energy needed to convert ADP to ATP.
Overall, oxidative phosphorylation is an important part of cellular respiration, allowing cells to efficiently produce ATP for energy.
