Cell Membranes and Molecular Movement

The yellow and brown portion of this image is:

• protein

• phopholipid

• carbohydrate

• cholesterol

The purple regions of the image represent:

• phospholipid

• cholesterol

• proteins

• carbohydrates

Examples of particles that can diffuse across through the phospholipid bilayer include:

• oxygen and carbon dioxide

• sugar

• water

• calcium ions
