What are the factors affecting enzyme activity?
Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.

What are the 4 factors that affect enzymatic function?
Factors Affecting Enzyme Activity
- Factor 1: Concentration of Enzyme.
- Factor 2: Concentration of Substrate.
- Factor 3: Effect of Temperature.
- Factor 4: Effect of pH.
- Factor 5: Effect of Activators.
What factors affect enzyme activity quizlet?
Terms in this set (6)
- Temperature. As temperature increases, the reaction rate increases, but if the temperature passes the optimal range, the enzyme will stop functioning.
- pH. Each enzyme has a specific pH.
- Enzyme Concentration.
- Substrate Concentration.
- Presence of Inhibitors.
- Presence of Activators.
What are the factors affecting enzyme activity class 11 biology?
Enzyme activity is affected by factors such as temperature, pH, the concentration of substrates, presence of inhibitors, allosteric regulators, etc.
What are the factors affecting enzyme activity PDF?
Substrate concentration: Increasing substrate concentration also increases the rate of reaction to a certain point, Effect of Water and effect of Inhibitors and activator.
…
- Temperature Effect.
- PH Effect.
- Concentration Effect.
- Water effect.
- Activators Effect.
How does temperature affect enzyme activity?
As the temperature increases so does the rate of enzyme activity. An optimum activity is reached at the enzyme’s optimum temperature. A continued increase in temperature results in a sharp decrease in activity as the enzyme’s active site changes shape.
How does pH affect enzyme activity?
Enzyme activity is at its maximum value at the optimum pH. As the pH value is increased above or decreased below the optimum pH the enzyme activity decreases.
What are the factors affecting enzyme activity PPT?
Effect of enzyme, substrate, product concentration, time, temperature, pH and presence of activators and inhibitors. Effect of enzyme, substrate, product concentration, time, temperature, pH and presence of activators and inhibitors.
What are the factors affecting enzyme activity Class 11?
Why pH affects enzyme activity?
The effect of pH
Within the enzyme molecule, positively and negatively charged amino acids will attract. This contributes to the folding of the enzyme molecule, its shape, and the shape of the active site. Changing the pH will affect the charges on the amino acid molecules.
How does pH effect enzyme activity?
How does salt affect enzyme activity?
High concentrations of any salt decrease water activity, and also that may reduce enzyme activity. In the case of divalent cations (Ca+2, Mg+2, etc) may form salt bridges between 2 COO- of acidic amino acids, that also can increase, decrease or having no effect on activity.
How does temp affect enzyme activity?
Why does temp affect enzyme activity?
This is due to the increase in velocity and kinetic energy that follows temperature increases. With faster velocities, there will be less time between collisions. This results in more molecules reaching the activation energy, which increases the rate of the reactions.
