le. Which investigation will help determine whether the new membrane protein is a channel protein involved in membrane transport? A. Add small nonpolar molecules to the extracellular space and measure the direction of particle movement of the molecules.
B. Measure the rate of extracellular fluid movement into the intracellular space.
C. Add more of the proteins to the plasma membrane and measure the rate of the particle movement
D. Remove ATP from the intracellular space and measure the rate of the particle movement into the intracellular space.
Root hair cells. Plants absorb water from the soil by osmosis. ... Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
