A) Concentration of K+
B) Concentration of Na+ and Cl−
C) Negatively charged proteins
D) Sodium-potassium pump
E) Plasma membrane is more permeable to this ion because of leak ion channels
Large Molecules
Large molecules, often referred to as macromolecules, include proteins, nucleic acids, carbohydrates, and lipids, essential for various structural, functional, and regulatory roles in organisms.
Concentration Differences
Variations in the amount of solutes present in different areas, leading to diffusion or osmosis.
Inside Cell
Refers to the internal environment of a cell, including its cytoplasm, organelles, and other components enclosed by the cell membrane.

Final Answer :
C
Explanation :
Negatively charged proteins are large molecules that cannot easily pass through the plasma membrane, thus they are trapped inside the cell. This contributes to the cell's internal negative charge and affects the osmotic balance and electrical gradient across the membrane.
