Which experimental design best tests whether aquaporin abundance causes a change in water movement rate?
A
Create membranes with different aquaporin abundance and different solute gradients, then compare final colors.
B
Measure aquaporin DNA sequence only, without measuring water movement.
C
Create membranes that differ only in aquaporin abundance, expose them to the same osmotic gradient, and measure initial water flux.
D
Use one membrane in isotonic solution and infer flux from solute size.
