Question
Plasma membrane is Fluid-structure due to presence of ______.
Options
Carbohydrates
Lipid
Glycoprotein
Polysaccharide
Solution
Plasma membrane is Fluid-structure due to presence of lipid.
Explanation:
Plasma membrane is a fluid structure due to the presence of phospholipids. The fluidity arises because phospholipids are not rigidly fixed; they can move laterally within the membrane, giving it a dynamic, fluid nature. Additionally, cholesterol (in animal cells) and proteins embedded in the membrane contribute to its fluidity and flexibility. It is mostly formed of a phospholipid bilayer structure with embedded proteins. The lipids may be saturated or unsaturated.
