Question

In an animal cell, where are the proteins of the electron-transport chain located?

a) ER membrane
b) Plasma membrane
c) Inner mitochondrial membrane
d) Mitochondrial matrix
e) Outer mitochondrial membrane

Answer 1

In an animal cell, the proteins of the electron-transport chain are located in the inner mitochondrial membrane.

Step-by-step explanation:

The proteins of the electron-transport chain in an animal cell are located in the inner mitochondrial membrane.

The inner membrane of mitochondria contains folds called cristae, which increase the surface area for biochemical reactions. The chain consists of integral proteins embedded in the inner membrane.

These proteins are involved in the transport of electrons during aerobic respiration, ultimately leading to the production of ATP.
