Nuclear matrix protein b. Lysosomal protein C. Peroxisomal protein d. Mitochondrial protein e. Chloroplast protein

Explanation / Answer

1) Ans a) The concentration of K+ is higher inside the cell while the concentration of Na+ is higher outside the cell. This gradient is maintained by the NA-K ATPase

2) Under resting potential, the inside of the cell is negative and outside positive. During an action potential, the cell in the inside of a neuron temporarily becomes postive and outside negative, as there is an exchange in ions across the axon, sodium ions entre the cell and potassium ions move out. Ans- b
