Mitochondria and Electron Chain Transport Quiz

The main function of mitochondria is to produce energy in the form of ATP through cellular respiration.

Electron chain transport is a series of chemical reactions that occur in the inner mitochondrial membrane, where electrons from NADH and FADH2 are passed along a chain of proteins to generate a proton gradient for ATP production.

Electron chain transport is essential for the production of ATP as it generates a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP through the enzyme ATP synthase.

<p>The components of the electron transport chain in mitochondria are NADH dehydrogenase complex, ubiquinone, cytochrome c reductase complex, cytochrome c, and cytochrome c oxidase complex.</p> Signup and view all the answers

<p>The electron transport chain generates ATP in mitochondria through oxidative phosphorylation. As electrons are passed through the chain, protons are pumped across the inner mitochondrial membrane, creating an electrochemical gradient. The flow of protons back across the membrane through ATP synthase drives the synthesis of ATP.</p> Signup and view all the answers
