Question

The ________ of the mitochondrion contains large-diameter pores that are permeable to ions and small organic molecules such as pyruvic acid. The ________ of the mitochondrion contains large-diameter pores that are permeable to ions and small organic molecules such as pyruvic acid. plasma membrane matrix inner membrane cristae outer membrane

Answer 1

Outer membrane.

Step-by-step explanation:

The outer membrane of mitochondria is the layer of double phospholipid and it is the mitochondrion gateway which separate it from the other cellular organelles present in the cytoplasm of the cell. The outer membrane have large diameter pores and due to these large pores, it is selectively permeable to ions and small organic molecules like pyruvic acid.
