Question

Phospholipase is an enzyme that cleaves the phosphate head group off a phospholipid molecule. The plasma membrane is not, however, permeable to the enzyme. Imagine a cell where phospholipid A is present in the layer of phospholipids facing the exterior of the cell, and phospholipid B is present in the layer of phospholipids facing the interior of the cell. After adding phospholipase to the medium in which the cell is growing, what would you expect to find in the fluid surrounding the cell/

Answer 1

Answer: Phosphate head group from A

Explanation: Phosopholipase can also be called Lecithinase. It is an enzyme that in the presence of water degrades or hydrolyzes phospholipids to give fatty acids and other lipophilic substances. There are four major kinds of Phospholipases and they are classified based on the kind of chemical bond which they attach or cleave themselves to. They are; Phospholipases A, B, C and D.
