Normally we think of CO2 as a gas because it is (at least when its in the atmosphere it is). However, it is a very different story inside of cells. CO2 is produced as a result of respiration inside mitoch...

The change from resting potential to action potential is caused by the stimulation of a recpetor, this causes a chain reaction which eventually leads to a positive environement inside the...

Osmoreceptors in the hypothalamus detect a change in the water potential of blood, this stimulates neurosecretory cells to make and release ADH. ADH travels down the axon to the terminal bulb in the poste...

6O₂ + C₆H₁₂O_{6   --->}  6CO₂ + 6H₂O

In words this is:

Oxygen + Glucose ---> Carbon dioxide + Water...

1. The action potential runs along the presynaptic membrane in a wave of depolarisation and activates the Voltage Gated Calcium ion channels. 2) Once these channels open, Ca2+ diffuses into the presyna...
