1. List and explain the difference between the minimum voltage and maximum voltage achieve in a nerve impulse

algol [13]

The normal membrane potential inside the axon of nerve cells is –70mV, and since this potential can change in nerve cells it is called the resting potential. When a stimulus is applied a brief reversal of the membrane potential, lasting about a millisecond, occurs. This brief reversal is called the action potential
A stimulus can cause the membrane potential to change a little. The voltage-gated ion channels can detect this change, and when the potential reaches –30mV the sodium channels open for 0.5ms. The causes sodium ions to rush in, making the inside of the cell more positive. This phase is referred to as a depolarisation since the normal voltage polarity (negative inside) is reversed (becomes positive inside). 

Repolarisation. At a certain point, the depolarisation of the membrane causes the sodium channels to close. As a result the potassium channels open for 0.5ms, causing potassium ions to rush out, making the inside more negative again. Since this restores the original polarity, it is called repolarisation. As the polarity becomes restored, there is a slight ‘overshoot’ in the movement of potassium ions (called hyperpolarisation). The resting membrane potential is restored by the Na+K+ATPase pump.

A cell pumps hormones out into the bloodstream; a process that requires energy. If 4 ATP were converted to ADP, how much energy

dedylja [7]

It is 122KJ of energy is used from the conversion of ATP to ADP because hydrolyses of 1 mole of ATP requires 30.5KJ of energy. Therefore, if 4 ATP is hydrolyses, it will be 4× 30.5=122KJ. ... This energy is given out because there is cleavage of high energy phosphate bond in ATP while converting it into ADP.
