The major components of plasma membrane are

1.   Lipids and proteins.

The principal components of plasma membrane are lipids, proteins and carbohydrates. Lipids constitutes of 40% of composition of mass of membrane volume (in which 75% of lipid is phospholipids, 20% of lipid is cholesterol and 5% of lipid is glycolipids), Protein accounts 50% of composition of mass of membrane volume and carbohydrate accounts for 10% of mass of the membrane volume.

Describe the changes that occur in the levels of plasma insulin, plasma glucagon, plasma free fatty acids, blood glucose, liver glycogen and blood ketone bodies when the body is in the fasting state

During fasting state insulin levels are decreased, instead of it glucagon levels are increased to supply tissues and organs with glucose. Blood glucose is supported on a stable level with...

What are the constraints on the architecture of membrane-integral proteins that lead to the membrane-spanning regions of such proteins being less diverse in structure than soluble proteins?

Membrane proteins have proven to be difficult to study owing to their partially hydrophobic surfaces, flexibility and lack of stability.

Analysis of glandular secretion indicates that it contains some DNA, RNA and membrane component such as phospholipids. What type of secretion is this and why

The presence of DNA, RNA, and membrane components suggest that the cell was destroyed during the process of secretion. This is consistent with a holocrine type of secretion.
