How can we increase the enzyme activity? Chemistry Question? ›

Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity.

Increasing the temperature of the enzymatic reaction, speeds the reaction as it increases the enzymatic activity increases, similarly the reverse happens and the enzyme activity and reaction speed decrease upon decreasing the reaction temperature.

The temperature: Each enzyme has an optimum temperature at which it works best. A higher temperature generally results in an increase in enzyme activity. As the temperature increases, molecular motion increases resulting in more molecular collisions.

The enzyme provides a template upon which the two substrates are brought together in the proper position and orientation to react with each other. Enzymes accelerate reactions also by altering the conformation of their substrates to approach that of the transition state.

Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

You're better off building a well-balanced diet that contains fresh fruits and vegetables, lean proteins and whole grains. These foods will naturally help support the work your digestive enzymes are already doing. Denhard suggests cutting highly processed, fatty foods from your diet, especially fried foods.

Enzyme activation can be accelerated through biochemical modification of the enzyme (i.e., phosphorylation) or through low molecular weight positive modulators. Just as with agonists of receptors, it is theoretically possible to bind molecules to enzymes to increase catalysis (enzyme activators).

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.

Short Answer. Answer: Two key methods of enzyme regulation are allosteric regulation and covalent modification. Allosteric regulation involves the binding of an allosteric effector to a specific site on the enzyme, causing a conformational change that alters its activity.

Enzymes are affected by pH and temperature

Various environmental factors are able to affect the rate of enzyme-catalysed reactions through reversible or irreversible changes in the protein structure. The effects of pH and temperature are generally well understood.

The rate of an enzyme-catalyzed reaction increases with an increase in the concentration of an enzyme. At low temperatures, an increase in temperature increases the rate of an enzyme-catalyzed reaction. At higher temperatures, the protein is denatured, and the rate of the reaction dramatically decreases.

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.

New enzyme must be added to regain enzyme activity. Adding more substrate w ill increase the rate of reaction. Adding more inhibitor should get the reaction up to speed again.

Changes in temperature or acidity can make enzyme reactions go faster or slower. Enzymes work best under certain conditions, and enzyme activity will slow down if conditions are not ideal.

Enzymes work by lowering the activation energy needed to start biochemical reactions. The activities of enzymes depend on the temperature, ionic conditions, and the pH of the surroundings.

Pancreatic juice contains several powerful hydrolases synthesized by the acinar cells. Enzyme secretion is stimulated by endocrine factors (cholecystokinin, secretin, and, much more weakly, gastrin) and neuronal factors [acetylcholine and vasoactive intestinal polypeptide (VIP)].
