Explain how the shape of the enzyme is related to its function.
a)
The shape of the enzyme makes the enzyme bind to specific substrates and lower their activation energy.
b)
The shape of the enzyme makes the enzyme react with water and increase the activation energy.
c)
The shape of the enzyme makes it a square and so it will fit into the locks of the other enzymes to make the reactions go faster.
d)
The shape of the enzyme has very little to do with how the enzyme will function in a cell.
