5 Questions
What are the coenzymes reduced to during glucose oxidation in glycolysis and the Krebs cycle?
NADH + H+
Where are the electrons from NADH + H+ transferred to during the electron transport chain?
Electron carrier proteins
What is the terminal electron acceptor in the electron transport chain?
Oxygen
What is formed as a product when the cytochrome oxidase complex transfers electrons from cytochrome c to oxygen?
Water
What is the energy derived from the movement of protons used for?
Synthesizing ATP from ADP and phosphate (oxidative phosphorylation)
Test your knowledge of cellular respiration and electron transport chain with this quiz. Explore how glucose is oxidized in glycolysis and the Krebs cycle, leading to the reduction of coenzymes NAD+ and FAD to NADH+H+ and FADH2 in the mitochondria. Understand the transfer of electrons and protons across the membrane as part of the electron transport chain.
