Question

How are electrons carried from complex $\mathrm{III}$ to complex $\mathrm{IV}$?

Short answer

Electrons are transported from Complex $\mathrm{III}$to Complex $\mathrm{IV}$ by cytochrome $\mathrm{c}$.

Step-by-step solution

Given information

We need to find out the electrons carrier of complex $\mathrm{IV}$from complex$\mathrm{III}$

Explanation

We know that

Electrons are transported from Complex $\mathrm{III}$to Complex $\mathrm{IV}$by cytochrome $\mathrm{c}$. The ${\mathrm{CoQH}}_2$provides it with two electrons. The electrons are then transferred from Complex $\mathrm{III}$to Complex $\mathrm{IV}$by cytochrome $\mathrm{c}$.
