Question

a. label the following on the lipid bilayer diagram: integral proteins, peripheral protein, glycoprotein, cholesterol, phospholipid, channel protein, carrier protein.
b. complete the venn - diagram to compare active and passive cell transport. passive transport active transport

Explanation:

A. Integral proteins span the lipid bilayer. Peripheral proteins are attached to the surface. Glycoproteins have carbohydrate chains attached. Cholesterol is inter - spersed in the bilayer. Phospholipids form the basic structure of the bilayer. Channel proteins form pores for transport. Carrier proteins change shape to transport molecules.
B. In the Venn diagram, for passive transport: occurs along a concentration gradient, does not require energy. For active transport: occurs against a concentration gradient, requires energy (usually ATP). In the overlapping part: both involve movement of substances across the cell membrane.

Answer:

A. Label the diagram as described above.
B. Fill the Venn - diagram: Passive transport: along concentration gradient, no energy; Active transport: against concentration gradient, energy required; Overlap: movement across cell membrane.
