What is a characteristic of phospholipids?

• They are fully nonpolar

• They are fully polar

• They have a polar head and a nonpolar tail

• They are solid at room temperature

What role does cholesterol play in the cell membrane?

• It acts as a source of energy

• It functions as spacers or connectors for phospholipids

• It serves as the primary transporter of ions

• It stores genetic information

What is the difference between peripheral and integral proteins?

• There is no difference; they are the same

• Peripheral proteins are on the exterior areas of the membrane, while integral proteins go through the membrane

• Peripheral proteins can go through the membrane, while integral proteins cannot

• Peripheral proteins are found inside the cell, while integral proteins are on the surface
