The right answer is C. Within the mitochondria’s inner membrane.

The mitochondrion is limited by two membranes of very different properties:

* the outer membrane contains a transmembrane protein, porin, which allows the passage of ions and water-soluble metabolites of molar mass <10.000 Da.

* The inner membrane is very rich in proteins and almost impermeable to ions and water-soluble metabolites.

The respiratory chain or electron transport chain is located in the inner membrane of mitochondria. Each mitochondrion contains thousands of copies of the electron transport chain.

PLEASE HELP!!Why might humans not have widespread regeneration abilities?
aev [14]

Answer:

Humans have some stem cells, but those cells are not easily available to help with healing. Most other mammals are the same, so they aren't good at regeneration either. Amphibians and some fish have stem cells that are more easily available, and are usually pretty good at regeneration.
