Enzymes are proteins that are biological catalysts
They reduce the activation energy required for a reaction to occur and thus speed up a reaction
Temperature, above a certain point (optimum temperature) causes them to break down and they are gradually destroyed (denaturing)
They work best at a particular pH (optimum pH) and are once again destroyed by low or high pH's
They have a specific shape, with one particular part, known as the active site, that is specific to the substrate they speed the reaction of. These means they are specific to one type of reaction.
They aren't used in the reaction so they're re-usable.
If it isn't one of these then it is not one of the properties of enzymes

Answer:
it is the base unit of temperature .
Explanation:
you can change celisus into kelvin by doing a quick math .
K = °C + 273
A.
Population density is the total number of organisms of a specie in a particular/fixed area; 150 bees in a 150 meter/square... it's density is arguably 1 bee to one meter/square.
Answer:
Sinoatrial Node
Explanation:
The sinoatrial node is like the natural pacemaker of the heart because it controls the heart beat or in other words, the cardiac rhythm. The sinoatrial node is found on the right atrium and it sends signals to both atria and then they contract. The signal is then carried to the atrioventricular node which spreads the signal to the ventricles and then the ventricles contract. The contractionof the ventricle is the pumping action of the heart.
