Below is represented the membrane of a red blood cell. G stand for glucose, and the membrane potential is negative (inside negatively charged). For each solute, assume that the number of symbols represents its relative concentration. Indicate which solute(s) can enter the cell without the need for a membrane protein. Indicate which solute(s) can readily enter the cell by simple diffusion. Indicate which solute(s) can readily enter the cell by facilitated diffusion. Indicate the solute(s) for which the movement across the membrane will not be influenced by the membrane potential. Indicate which solute(s) can readily enter the cell by channel proteins mediated facilitated diffusion. Indicate which solute(s) can only enter the cell by earner proteins mediated facilitated diffusion. Indicate which solute(s) can only enter the cell by active transport. Indicate the solute(s) for which the movement across the membrane will be additively influenced by the membrane potential and the concentration gradient. Indicate the direction of net movement.

Solution

O₂ , glucose enter the cell without the need for membrane protein.

2. Oxygen molecules can diffuse through membrane by simple diffusion.

3. Glucose can readily enter into the cell membrane via facilitated diffusion.

4.oxygen can move across the cell membrane without the influence of membrane potential

5. Potassium (K) , sodium (Na) , chloride (cl) ions can pass through the membrane through channel proteins.

6. Glucose molecules can move through membrane by facilitated diffusion.

7. Sodium (Na) and potassium (K) ions can enter the cell by active transport.

8. The transport of ions through the membrane will be influenced by membrane potential.. Here sodium will an inward movement as there are more sodium ions outside the cell, potassium ion will move outside as there are more potassium ions inside the cell. Chlorine will have a net inward movement as there are more chloride ions is present out side the cell. Glucose also will have a inward flow.
