Question

question 1
the electrical properties of cells are the result of:
a ion concentration differences across the plasma membrane
b phospholipids in the cell membrane
c receptor sites that are present on the plasma membrane
d phosphorylation reactions within the cytoplasm
e none of these choices is correct

Explanation:

The electrical properties of cells, such as the resting membrane potential, are due to the unequal distribution of ions (e.g., \(Na^+\), \(K^+\)) across the plasma membrane. Phospholipids form the membrane structure but don't directly cause electrical properties. Receptor sites are for signal - binding. Phosphorylation reactions are energy - related processes.

Answer:

A. ion concentration differences across the plasma membrane
