The graph shows the effect of an enzyme on a reaction. [Figure 12.1] Which row identifies X, Y and Z?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
AX: catalysed reaction, Y: uncatalysed reaction, Z: energy lost by product
BX: catalysed reaction, Y: uncatalysed reaction, Z: overall energy lost during reaction
CX: uncatalysed reaction, Y: catalysed reaction, Z: energy gained by product
DX: uncatalysed reaction, Y: catalysed reaction, Z: overall energy released during reaction
✓ Correct answer
D: X: uncatalysed reaction, Y: catalysed reaction, Z: overall energy released during reaction
