enzymes
part 2: analyzing enzyme activity graphs

1. graph (a) shows that this enzyme will work best at what type of temperatures, low or high? ______
2. graph (b) shows that this enzyme will work best at what type of temperatures, low or high? ______
3. graph (c) shows that this enzyme will work best at what type of ph, acidic, neutral or basic? ______
4. graph (d) shows that this enzyme will work best at what type of ph, acidic, neutral or basic? ______

(graphs labeled (a), (b), (c), (d) with axes: (a)(b) x: enzyme efficiency, y: temperature; (c)(d) x: acid-base (ph) scale, y: ...)

Explanation:

1. Graph (a) Enzyme Temperature Optimum

Graph (a) has enzyme efficiency increasing with temperature (no decline shown yet), so it works best at low temperatures (before reaching the peak where it might denature, but here the curve is still rising, implying low temp is optimal so far).

Graph (b) shows a peak (efficiency rises then falls), indicating a moderate - high temp optimum (the peak is at a relatively high temp range for enzyme activity, as it’s the point of maximum efficiency before denaturation).

Graph (c)’s peak (maximum efficiency) aligns with the middle of the acid - base axis (neutral pH, around pH 7, as the curve is symmetric around the center of the acid - base scale).

Answer:

Low

2. Graph (b) Enzyme Temperature Optimum
