How a phospholipid is related to a cell
WebAnswer (1 of 3): The fluid mosaic model stipulates that a cell membrane is made up of a phospholipids bilayer with various proteins associated with the membrane. A phospholipid bilayer consists of two monolayers of phospholipid molecules. The phosphate heads are hydrophillic so face towards the ... Web1.1 Definition of phospholipases. Phospholipases are a ubiquitous group of enzymes that share the property of hydrolyzing a common substrate, phospholipid. Nearly all share another property; they are more active on aggregated substrate above the phospholipid’s critical micellar concentration (cmc).
