A lot of chemical reaction only take place when a certain activation energy is reached. This is the kind of energy you need to start a reaction. In many cases this activation energy might mean that a chemical in our bodies would have to be above the temperature that would kill us just to take place!
A way around this problem is the enzyme, which can lower the activation energy by using something called an active site, which exists on the enzyme itself. Normally it takes energy to break bonds and split chemicals-up, or split molecules. This is where the enzyme comes in: the active site links with the molecule of the chemical you want to split, and it allows it to split-up.
Its worth noting that enzymes break-down above a certain temperature (we say they denature), which is why the body really works hard to keep your core temperature down.
Hey
In biological chemical reactions, examples of these are called enzyme inhibitors. Enzymes speed up reactions, but enzyme inhibitors slow them down. This can be by either competing with the reactants for a spot on the enzyme, or by altering the enzyme's structure so that it does not speed up reactions anymore. In either case, enzyme inhibitors slow down chemical reactions.

The shape allows the enzyme to carry out specific chemical reactions.
Yes, that is correct.

No. An enzyme is a chemical that speeds up chemical reactions without adding any energy to them. Sugar is an energy source that makes some chemical reactions happen. They are different things and work on different principles.

In biological systems an enzyme speeds up the reaction without changing it. In other chemical reactions this function is achieved by a catalyst.
its called an enzyme
an enzyme is protien that catalyzes chemical reactions for organisms
This varies per enzyme and what it catalyzes but chemical reactions that result in an increase in temperature often speed up enzyme catalysis.

An enzyme is a type of protein that speeds up chemical reactions in living things by lowering the activation energy of said reactions.
