Question

which of the following describes the structure of a mitochondrion? select all that apply a the smooth outer membrane separates the mitochondrion from the cytosol. b a mitochondrion has two phospholipid membranes. c the inner mitochondria membrane has many folds, called cristae. d the fluid - filled inside of the mitochondrion is called matrix.

Explanation:

Mitochondria have a smooth outer - membrane separating them from the cytosol. They possess two phospholipid membranes. The inner membrane has folds called cristae and the fluid - filled interior is the matrix. All these statements are correct descriptions of mitochondrial structure.

Answer:

A. The smooth outer membrane separates the mitochondrion from the cytosol.
B. A mitochondrion has two phospholipid membranes.
C. The inner mitochondria membrane has many folds, called cristae.
D. The fluid - filled inside of the mitochondrion is called matrix.
