Current Question (ID: 14931)

Question:

Match each item in Column I with one item in Column II and choose your answer from the codes given below: Column I I. Influx of sodium II. Efflux of potassium III. Na⁺/K⁺ pump IV. Ca⁺⁺ Column II 1. Original establishment of RMP 2. Repolarization 3. Depolarization 4. Plateau in cardiac muscles Codes:

Options:

1. 3 2 4 1
2. 2 1 4 3
3. 2 1 3 4
4. 3 2 1 4

Solution:

The correct matching is: I - 3, II - 2, III - 1, IV - 4. Influx of sodium leads to depolarization, efflux of potassium causes repolarization, Na⁺/K⁺ pump is responsible for the original establishment of RMP, and Ca⁺⁺ is involved in the plateau phase in cardiac muscles.
