Average Candidate Response
The given plot demonstrates the connection between energy and reactants/products. The enzyme lowers the activation energy required to carry out a forward reaction. Without an enzyme, additional energy must be supplied to carry out the same forward reaction.

Excellent Candidate Response
Excellent candidates will use the 'BlackStone Tutors Six Point Approach for Data Analysis'
The given plot describes how a reaction proceeds with and without an enzyme. On the x-axis, reaction coordinates are labelled and on the y-axis, energy (Activation energy) is labelled. The graph demonstrates that in the presence of an enzyme (red line), a lower activation energy is required to yield the same volume of products. Without the enzyme (blue line), additional energy must be supplied to carry out the same reaction. This is explained by the fact that in order for a chemical reaction to take place and reactants to be converted to products, chemical bonds must be broken and rearranged. The energy needed to break bonds is termed “activation energy.” Enzymes tend to offer an alternative pathway for reactions with a lower activation energy, thus reducing the amount of energy required to convert reactants to products. The graph itself is well presented and easy to understand, and is from a commonly utilised (although sometimes inaccurate) source.
