The value that stays the same as long as there are no signals in the neuron is known as resting potential.
Neurons are the nerve cells. These are the longest cell in the human body. The structure of a neuron comprises of a cell body from which arise the various branch-like extensions called the dendrites. From one end emerges the axon that ends at the axon terminal.
Resting potential is the potential difference of ions across the plasma membrane when the cell is resting and no nerve impulse is being conducted. The value of resting potential is approximately -70 mV in majority of the neurons.

Answer:
enzymes are proteins that speed up chemical reactions that take place in the cell.
The answer to question 1 is B. The answer to question 2 I think it's A.
The correct answer is: C) ATPase activity must be pumping calcium from the cytosol to the SR against the concentration gradient.
From the example above, we can see that the concentration of calcium is higher in the SR than in cytosol, which means that calcium is moved from the area of lower concentration (cytosol) to the area of higher concentration (SR). This movement is against the concentration gradient and that is the reason for ATPase to act. This process requires energy.
