The following statements about the composition of membranes are TRUE:

1. Phospholipids are major membrane lipid components: This is true. Phospholipids are the primary type of lipid found in the bilayer of cell membranes. They have a hydrophilic (water-loving) head and two hydrophobic (water-fearing) tails, which allows them to form a barrier between the inside and outside of the cell.

2. Integral membrane proteins traverse the cell membrane: This is also true. Integral membrane proteins are permanently attached to the cell membrane and can span across the entire membrane (transmembrane proteins), or only part of the way through.

3. Cholesterol is the major steroid found in membranes: This is true as well. Cholesterol is a type of lipid that is found in the cell membrane. It helps to regulate the fluidity of the membrane and also plays a role in various cellular functions.

The statement that "peripheral membrane proteins are only found on the exoplasmic face of membranes" is FALSE. Peripheral membrane proteins can be found on both the inside (cytoplasmic) and outside (exoplasmic) surfaces of the cell membrane. They are not embedded in the lipid bilayer like integral proteins, but instead are loosely attached to the membrane surface or to integral proteins.
