Regions with high ATP consumption

What is the function of microtubules in relation to mitochondria?

They move mitochondria inside the cell

Where do high-energy electrons used by mitochondria come from?

Electron transport chain in the inner mitochondrial membrane

What is the process by which ATP stores energy?

Oxidative phosphorylation

Which components are part of the electron transport chain in mitochondria?

Cytochrome c and ATP synthase

What is the main role of the outer membrane of mitochondria?

Facilitating the entry and exit of molecules like pyruvate and ATP
