True or false: The lipids are arranged in the membrane with the polar heads towards the inner side.

Read the assertion and reason carefully to mark the correct option in question. Assertion: In the cell membrane , the non-polar tail of saturated hydrocarbons is protected from the aqueous environment. Reason: The lipids are arranged within the membrane with polar head towards the outer sides and the hydrophobic tail towards the inner part.

Go through the following statements (i) In human beings, the membrane of the erythrocyte has approximately 52 percent lipids and 40 percent proteins (ii) Lipids are arranged within the membrane with the hydrophobic tails towards the outer side and the polar head towards the inner side. (iii) As the polar molecules cannot pass through the non- polar lipid bilayer, they require a carrier protein of the membrane to facilitate their transport across the membrane (iv) The endomembrane system includes endoplasmic reticulum, Golgi complex, lysosomes and peroxisomes Find out the wrong peroxisomes :

A: Lipids are arranged within the cell membrane with hydrophobic tails towards the inner part R:This ensures that non-polar tail of saturated hydrocarbons is protected from the aqueous environment.

Tell how the phospholipids are arranged in the plasma membrane. What other lipids are present in the membrane, and what functions do they serve?

The special arrangement of the lipids in the cell membrane ensures that the

True or false: The integral proteins are partially or totally buried in the membrane.

State true or false. In alternate arrangement, a set of three or more leaves grows from the same node.

State true or false. The lipid portion of a plasma membrane acts like a liquid at the temperature of the human body.
