What are the different types of enzyme activity?

What are the different types of enzyme activity?

What are the different types of enzymes?

• Carbohydrase breaks down carbohydrates into sugars.
• Lipase breaks down fats into fatty acids.
• Protease breaks down protein into amino acids.

How does substrate concentration 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. As the substrate concentration increases so does the rate of enzyme activity. An optimum rate is reached at the enzyme’s optimum substrate concentration.

How substrate concentration affects enzyme activity?

(B) As the concentration of substrate increases, the enzyme becomes saturated with substrate. As soon as the catalytic site is empty, more substrate is available to bind and undergo reaction. The rate of reaction when the enzyme is saturated with substrate is the maximum rate of reaction, Vmax.

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 is the effect of substrate concentration on enzyme activity Class 11?

The substrate concentration: As the substrate concentration increases, the enzyme activity increases, until a maximum limit is attained. After which no more sites are available for more substrate molecules to bind to the enzyme.

What are the factors that affect enzymatic activity?

What are the Factors that Affect the Enzymatic Activity? Several factors affect the rate of an enzyme catalyzed reaction. Among these are enzyme concentration, substrate concentration, temperature and pH. Besides, some molecules (activators) increase enzyme activity, while others (inhibitors) retard enzymatic activity.

What is the relationship between temperature and enzyme activity?

Velocity of an enzyme reaction increases with increase in temperature up to a maximum and then declines. A bell-shaped curve is usually observed (Fig. 66.4). The optimum temperature for most of the enzymes is between 40°C-45°C. However, a few enzymes (e.g. venom phosphokinases, muscle adenylate kinase) are active even at 100°C.

What is the effect of pH on enzyme activity?

PH: Enzymes are affected by changes in the pH. The most favourable pH, at which an enzyme exhibits its maximum activity, is known as the optimum pH for the enzyme. Extremely high or low pH values generally result in complete loss of enzymatic activity. The optimum pH value varies greatly from enzyme to enzyme.

What happens to enzyme activity in the absence of water?

Ø Enzyme activity is suppressed in the absence of water. Ø In dry seeds, the enzymes are almost inactive. Ø Hydration of the cells is necessary for the enzyme activity. Ø Water provides a medium for the enzymatic reaction to take place.
