Question

Question 18 (6 points, 1 point for each correct answer): Match the following processes (designated I, II, or III) that represent various types of transport across a biological membrane with the statements designated A-D: 1. Water diffusion through the lipid bilayer of the biomembrane. II. Glucose transport via the glucose transporter in the plasma membrane. III. Pumping of protons across the lysosome membrane by a proton pump similar to the ATP-synthase complex. Write down your answers in the blank space next to each statement below. Note, that more than one answer may apply to each statement: A. Process occurs down the concentration gradient: B. Processes establishes a concentration gradient: C. Process is energy-dependent: D. Process requires a dedicated transmembrane protein:
