What are the 4 factors that affect enzymatic function?

These factors are:

• Enzyme Concentration. The transient bonds between enzymes and their substrates catalyze the reactions by decreasing the activation energy and stabilizing the transition state.
• Substrate Concentration.
• pH Value.
• Temperature.
• Effector or Inhibitor.

What are three conditions that affect the activity of an enzyme quizlet?

Terms in this set (12)

• Temperature too high. Enzymes denature.
• High temperature. Reactions happen faster.
• Temperature too low. Reactions happen slower.
• pH. Different proteins work best at different pH’s.
• pH too high/too low.
• Substrate concentration.
• Enzyme concentration.
• Enzyme cofactors (vitamins)

What three things inhibit enzyme activity?

There are three common types of enzyme inhibition – competitive, non-competitive and substrate inhibition.

How does time affect enzyme activity?

The longer an enzyme is incubated with its substrate, the greater the amount of product that will be formed. As a result, the rate of formation of product slows down as the incubation proceeds, and if the incubation time is too long, then the measured activity of the enzyme is falsely low.

What affects enzyme activity quizlet?

As temperature increases, the reaction rate increases, but if the temperature passes the optimal range, the enzyme will stop functioning. Each enzyme has a specific pH. If it is exposed to a different pH, the enzyme’s activity will slow down or stop. Increasing substrate concentration increases the reaction rate.

What environmental factors affect enzymes?

The environmental factors that affect enzyme shape are temperature, PH level and inhibitors.

What are the 3 environmental factors that affect enzyme efficiency?

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 three kinds of enzyme controlled reactions?

Inhibition. We will first discuss four types of enzyme inhibition – competitive, non-competitive, uncompetitive, and suicide inhibition. Of these, the first three types are reversible.

How substrate affect enzyme activity?

Enzymes will work best if there is plenty of substrate. As the concentration of the substrate increases, so does the rate of enzyme activity. However, the rate of enzyme activity does not increase forever. As the substrate concentration increases so does the rate of enzyme activity.

How does pH level affect enzyme activity?

Enzymes are also sensitive to pH . Changing the pH of its surroundings will also change the shape of the active site of an enzyme. 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.

What are the factors affecting enzyme activity Slideshare?

Effect of enzyme, substrate, product concentration, time, temperature, pH and presence of activators and inhibitors.
