Which statements describe some enzyme actions?
1) Enzymes hold reacting molecules in such a way that their reactive groups are brought close together.
2) In an enzyme-catalysed reaction, more molecules have sufficient energy to react than in the absence of the enzyme.
3) Reactions catalysed by enzymes take place at a lower temperature than they would without the enzyme.
