If the optimum temperature for human chemical activity is body temperature 36.6 degrees celsius what would happen to the rate of reaction of amylase as it approached zero degrees celsius?

The proteins that comprise the amylase would begin to denature. In other words, the chemical and ionic bonds that hold the protein together would begin to break apart, and it would start to unravel. In general, reaction rate increases with temperature; the usual rule of thumb for temperatures near room temperature is that the rate doubles for every 10 degrees C (use the Arrhenius rate equation if you want exact figures).

Which part of a chemical reaction is most changed by enzyme activity?
Reaction equilibrium
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
What is it called when a chemical reaction occurs and the temperature of the surroundings goes down?
This is an endothermic reaction.
What do concentration surface area and temperature have in common?
They can all affect the rate of a chemical reaction.
What changes occur when a chemical reaction?
Changing temperature, density and pressure occur when a chemical reaction.
How does increasing the temperature effect a chemical reaction?
Raising the temperature makes chemical reactions faster.
How are temperature and the Arrhenius theory related?
The reaction rate of a chemical reaction is dependent on temperature.
Which part of a chemical reaction is most changed by enzyme activity?
Reaction equilibrium
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
What is a chemical reaction is endothermic?
An endothermic reaction is a chemical reaction that absorbs energy. Such reactions usually produce a temperature drop.
Does the change of temperature will slow or faster the chemical reaction?
No, an increase in temperature will speed up the reaction. This is because the heat energy is transferred into kinetic energy (movement energy) in the reactors and this increases their speed and so increases the rate at which they collide with each other, increasing the rate of the chemical reaction.
Why does a change in temperature indicate that a chemical reaction may occur?
Because a chemical reaction has different sign's. And heat is one. But if the temperature is dropping then it is not going through a chemical change.
Does temperature effect the rate of chemical reaction?
yes.
How might a thermometer help you decide if there was any chemical change on mixing iron and charcoal?
For a chemical change to occur, there must be a chemical reaction. A chemical reaction would be either endothermic (uses energy, mostly heat), or exothermic (produces energy, again mostly heat). Any change in temperature of the reactants, as measured by a thermometer, will tell you not only ifa chemical reaction occurred, but also which kind of chemical reaction. No temperature change usually indicates that no reaction has occurred, a decrease in temperature would indicate an endothermic reaction, while an increase in temperature would indicate an exothermic reaction.
What leads to an increase in the rate of a chemical reaction?
Either (or both) an increase in the reactants or temperature will increase the rate of a chemical reaction.
Which of the following tends to increase the rate of a chemical reaction?
Increasing the temperature of the reactants can increase the rate of the chemical reaction.
What is it called when a chemical reaction occurs and the temperature of the surroundings goes down?
This is an endothermic reaction.
