Which component of plasma membrane increase the fluidity?
1 Phospholipids
2 Cholesterol
3 Carbohydrates
4 Proteins
Explanation:
Cholesterol extend in between the bilayer and increase the fluidity of the plasma membrane.

Assertion : A cell membrane shows fluid behaviour. Reason : A membrane is a mosaic or composite of diverse proteins and lipids.
1 Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false
Explanation:
The plasma membrane is the combination of phospholipids, cholesterol and proteins. Carbohydrates attached to lipids (glycolipids) and to proteins (glycoproteins) extend from the outward facing surface of the membrane.

Movement of ions or molecules against electrochemical gradient is called ________
1 Diffusion
2 Passive gradient
3 Active transport
4 Osmosis
Explanation:
Cell membranes form a region of their lower concentration to a region of their higher concentration in the direction against concentration gradient. With the loss of energy in the form of ATP is called active transport.
