Question

1. describe the optimum range with correct enzymatic activity

enzymatic activity
graph:
ph
temperature
concentration

Explanation:

The problem is about describing the optimum range for enzymatic activity in relation to pH, temperature, and concentration. Enzymatic activity and its dependence on these factors are studied in Biology (a subfield of Natural Science). For pH: The graph likely shows a bell - shaped curve (or a range) where enzyme activity is maximum between two pH values (e.g., for many enzymes like pepsin it's acidic, for amylase neutral, for trypsin alkaline). For temperature: The graph shows enzyme activity increases with temperature up to an optimum (like 37°C for human enzymes, 40°C as seen here), then decreases as temperature denatures the enzyme. For concentration: As enzyme concentration increases, activity increases (assuming substrate is not limiting) until a point where substrate becomes the limiting factor, but the graph here shows a curve that might be approaching a saturation point. The optimum range for pH is a narrow range around the pH where activity is highest, for temperature around the peak temperature (e.g., 35 - 45°C if the peak is 40°C), and for concentration, as long as substrate is sufficient, activity increases with enzyme concentration.

Answer:

• pH Optimum Range: A narrow range (e.g., if the graph shows peak activity around pH 7, the range could be 5 - 9, depending on the enzyme) where enzymatic activity is maximum. Enzyme activity is low outside this range due to changes in the enzyme's active site structure.
• Temperature Optimum Range: Around the temperature where the enzyme activity graph peaks (e.g., from the graph, around 35 - 45°C with 40°C as the peak). Below this range, kinetic energy is low; above, the enzyme denatures.
• Concentration Optimum Range: As enzyme concentration increases, activity increases (assuming substrate is in excess). The range is such that as long as substrate is available, higher enzyme concentration leads to higher activity (the graph shows a curve that approaches a maximum as substrate may become limiting, but the optimum range for enzyme concentration, in terms of maximizing activity, is as high as possible while substrate is not limiting).
