9. Water moves across a cell membrane through a channel protein, whereas glucose moves across a cell membrane via a carrier protein. Which statement provides a valid comparison of these two membrane transport systems? Glucose moves in a direction from high to low concentration, while water moves in a direction that is not governed by differing solute concentrations. Water transport occurs without the cell using energy, whereas glucose transport requires energy input by the cell. A cell can add more sites for water transport to increase water movement across the membrane but cannot achieve the same result for glucose using a similar strategy. Several water molecules move one after the other through the opening provided by a channe protein, while glucose is transported across the membrane via a carrier protein one molecule at a time. Genetic mutations can alter glucose transport into a cell but cannot alter water transport.

Expert Solution
Step 1

Passive transport is a membrane transport system applicable for small molecules or ions that do not use energy to move substances across cell membranes. It is divided into several types filtration, simple diffusion, facilitated diffusion, and osmosis.
