What type of protein assist in moving specific particles across the membrane?

• Membrane-spanning

• Surface

• Cholesterol

• Carbohydrates

Identify cholesterol molecule

Plasma membranes are selectively permeable. This means

• anything can pass in and out

• the membrane regulates the passage of the material in and out of the cell

• glucose cannot enter the cell

• cholesterol cannot enter
