    Enzymes are proteins. Specifically, enzymes are proteins that catalyse chemical reactions.

    You need enzymes so reactions can take place at lower temperatures and other more practical conditions.

    Cells need enzymes in order to catalyze (speed up) chemical reactions inside the cell. Without enzymes, the chemical processes would be too slow and the organism would not survive.
    Hope this is helpful

    There's loads: but to name a few processes, respiration, DNA replication, transcription, translation, cell signalling

    I think the easiest process to understand is digestion. You have enzymes, which are a form a very specifically folded proteins, to speed up the breakdown of your food. Take bread, for example. It's composed of really long chains of sugar molecules all bonded together. Amylase, which is an enzyme, binds strongly to the links, and breaks them down to separate the long chain into separate glucose molecules. These can then be absorbed into the blood.

    The same thing happens with many other processes. ATP, which is the form of energy currency in the body, uses an enzyme (ATPase - notice how enzymes usually end in "-ase") to break down the ATP into ADP and a phosphate to release that energy. Essentially, enzymes (and there are lots of different types because each enzyme is shaped in a very specific way so it only targets its designated molecule) speed up all these processes that are essential to live!
