The curve given below shows enzymatic activity with relation to three conditions (pH, temperature and substrate concentration). What do the two axes (x and y) represent?
- Ax-axis: Enzymatic activity; y-axis: Temperature
- Bx-axis: Enzymatic activity; y-axis: pH
- Cx-axis: Temperature; y-axis: Enzyme Activity
- Dx-axis: Substrate concentration; y-axis: Enzymatic Activity
Solution & Step-by-step Explanation
The graph shows a bell-shaped curve. This is characteristic of the effect of Temperature or pH on enzyme activity. Enzymes have an optimum temperature/pH where activity is highest; activity declines both above and below this optimum. Usually, the independent variable (Temperature/pH) is on the x-axis and the dependent variable (Activity) is on the y-axis.
