what is an Enzyme | protein that speeds up chemical reactions without getting changed |
What are the substances called that bind to the active site on the enzyme? | substrates |
What do we call the substances that are on the left side of the reaction called? | reactant |
What do we call the substances that are on the right side of the reaction called? | product |
Enzymes change shape during the reaction but then return to their original shape and are not permanently changed. Why is that so significant to their function? | they are reusable |
If there are two molecules that are changed into one by an enzyme, did the enzyme form or break covalent bonds between the molecules? | break |
If there is one large molecule that is changed into two smaller ones by an enzyme, did the enzyme form or break covalent bonds between the molecules? | form |
