Question

Question 2 (1 point): 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 I. 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 needs transmembrane protein transporter/channel: B. Process is energy dependent: C. Processes establishes a concentration gradient: D. Process occurs down the concentration gradient:

Explanation / Answer

ANS.1) Water diffusion through the lipid bilayer of the biomemebrane - process occurs down the concentration gradient.

2)Glucose transport via glucose transporter in the plasma membrane- the process is energy dependent.

3)pumpig of proteins across the lysosome membrane by proton pump similar to the ATP -synthase complex- process needs transmembrane protein transporter / channel.
