To a certain point, heat will increase enzyme activity because more collisions will be taking place between the enzyme and substrates. However, if there is too much heat, an enzyme can denature (change its shape) and inactivate. This is caused because the increase in heat disrupts the bonds in the tertiary structure of the enzyme. Due to the disruption of bonds, the enzyme can no longer interact with the substrates.
yes.
Heat would make most enzymes unnecessary as added heat would allow (many) reaction to achieve activation energy without the need of a helping enzyme. In a biological system most enzymes are proteins and as heat denatures proteins the effect would be to destroy their functionality.
Enzymes can be denatured by heat or acidity
Freezing doesn't effect the enzymes since freezing does not permanently affect enzyme structure. Boiling permanently changes the structure and can change the enzymes.
At excessive temperatures, enzymes usually denature or break down into other molecules, thus failing to preform their specific function.Other than that, heat does not affect enzymes much but it does increase the speed of the reaction.
Enzymes are required for nearly all biological processes from DNA replication to how drugs will effect your system. You can't go in depth in biology without understanding how they effect the system.

it can change the shape of enzymes & active site so the enzyme is unable to work
It has no effect
not a thing

Pineapple contains an enzyme which prevents gelatin from setting. Heat destroys (denatures) enzymes.
large amounts of heat can denature enzymes and render them useless
The major thing that has an effect on an enzyme is heat. If the enzyme is exposed to a large amount of heat than it denatures, which means that it is no longer functional. Enzymes work at their best at an OPTIMUM range, that is at about 30-35 degrees Celsius. The enzyme will denature at about 47-50 degrees Celsius.
Enzymes do not heat up molecules so they can react. Enzymes are catalysts that lower the activation energy of a reaction but are not consumed in the process.
enzymes undergo denaturation when heated to high temperatures
Enzymes have no effect on the overall thermodynamics of a reaction.
