Question: What makes up an enzyme?

Good question! Enzymes are proteins. Basically your DNA contains specific sequences that code for the order of amino acids(small molecules considered the building blocks of life) that make up chains. The reason amino acid order is so vital is that they have different ways of interacting with each other which gives the protein a really specialised shape,this is how proteins are all over your body doing different jobs!

Enzymes shape means that they can recognise a sequence in other proteins and cut them-this is why they are used in digestion,breaking down the food you eat!
