Question

in fig. 5b, the cytochrome c is used to measure activity of cytochrome c oxidase. what is the best explanation of this? when bpa inhibits cytochrome oxidase, it produces more cytochrome c. cytochrome c oxidase hydrolyzes cytochrome c. cytochrome c oxidase steals an electron from cytochrome c. cytochrome c oxidase is oxidized by cytochrome c. cytochrome c oxidase catabolyzes cytochrome c.

Explanation:

Cytochrome c oxidase is the terminal enzyme of the mitochondrial respiratory chain. It receives electrons from cytochrome c. Measuring cytochrome C can reflect the activity of cytochrome c oxidase as cytochrome c oxidase steals an electron from cytochrome c in the electron - transfer process.

Answer:

cytochrome c oxidase steals an electron from cytochrome c.
