Answer 2

Nitrogenous bases such as choline and serine are the significant parts of Phospholipids.

Explanation: Choline and serine are found in the plasma membrane as a significant part of the phospholipid present in the plasma membrane.

• The major components of the plasma membrane of animal cells are phospholipids.
• The structure of phospholipids consists of a fatty acid chain that is attached to the glycerol backbone.
• There are two major types of phospholipid found in the plasma membrane: phosphatidylserine and phosphatidylcholine.
• Serine is the part of phosphatidylserine and Choline is the part of phosphatidylcholine.
• Thus, the correct answer is B. Phospholipids.
