Consider the statements as True/False. I. The axoplasm inside the axon contains a high concentration of K+ and negatively charged proteins. II. The axoplasm inside the axon contains a low concentration of Na+. III. The fluid outside the axon contains a low concentration of K+. IV. The fluid outside the axon contains a high concentration of Na+ and negatively charged proteins. The correct option is
Answer: (C)
Solution
The resting axoplasm genuinely has a high concentration of K+ and negatively charged proteins (I, true) and a low concentration of Na+ (II, true), while the extracellular fluid has a correspondingly low concentration of K+ (III,
