And so when enzymes decrease the activation energy, EA, they essentially decrease this entire exponent. And since the exponent is negative, what that means is this entire quantity will increase. And so by decreasing the activation energy our enzyme increases the rate constant and that's precisely what increases the rate of that reaction. So remember, inside our body the temperature remains constant. The core temperature is about 37 degrees Celsius. And that means all the reactions taking place inside our body take place at a constant temperature.
