Question

The plasma membrane found in both prokaryotic and eukaryotic cells is composed of a/an _______, which is semipermeable and controls the flow of molecules into and out of the cell.
Whereas lysosomes are primarily involved with the breakdown of proteins and polysaccharides, _______ are involved in lipid and fat breakdown.

Answer 1

Answer:

The plasma membrane found in both prokaryotic and eukaryotic cells is composed of a/an lipids (phospholipids), which is semipermeable and controls the flow of molecules into and out of the cell.

Whereas lysosomes are primarily involved with the breakdown of proteins and polysaccharides, lipases are involved in lipid and fat breakdown.

Explanation:

The plasma membrane of both prokaryotic cell and eukaryotic cell is made up of specialized lipids called phospholipids that separates the cell components from the outside environment.

Lysosomes contain different hydrolytic enzymes like proteases, lipases and nucleases which breakdown proteins, lipids and nucleic acids. It does this because they are no longer useful for the cell.
