The graph below shows how enzymes affect biological reactions.
Use the graph and your own knowledge of enzyme function to explain how enzymes function as biological catalysts.
The graph shows how the addition of a molecule named here as molecule X affects the rate of an enzyme-controlled reaction.Â
Describe how the addition of molecule X affects the rate of reaction in the graph.
The image below shows how molecule X interacts with the enzyme.
Use the image to explain the results shown in the graph in part (b).Â
The image below shows another molecule, molecule Y.
Suggest how molecule YÂ might interact with the enzyme shown in part (c).
Sketch a line on the graph from part (b) to show how molecule Y might affect the rate of reaction.
