Question

Describe the ultrastructure of cell membrane​

Answer 1

Answer:

The cell membrane is a fluid matrix made of a phospholipid bilayer. Each lipid molecule has a hydrophilic, phosphorylated "head" and a hydrophobic, fatty acid "tail". ... Small, hydrophobic molecules can traverse the cell membrane via simple diffusion.

Answer 2

• ⟼ Mitochondria are bounded by an envelope consisting of two concentric membranes, the outer and inner membranes.

• ⟼ The space between the two membranes is called inter-membrane space.

• ⟼ A number of invaginations occur in the inner membrane; they are called cristae.
