Enzymes are biological catalysts. An enzyme provides activation energy pathways thereby increasing the rate of reaction. Enzymes work on the basis of their nature .different enzymes are used for different purposes like manufacture of wine by fermentation of carbohydrates ,sweet syrup from corn starch,cheese by coagulation of milk.enzymes are essential part for digestion without enzymes it would take us 50 years to digest a single meal .

What is the term for an enzyme's shape when change so it can no longer work?
The term for an enzyme's shape changing so it can no longer work is denaturation. This can be caused by factors such as high temperature, extreme pH, or exposure to certain chemicals. Once denatured, the enzyme loses its specific shape and can no longer function properly.
What is the significance of the enzyme curve in understanding the catalytic activity of enzymes?
The enzyme curve helps us understand how enzymes work by showing the relationship between enzyme concentration and reaction rate. It helps us determine the optimal conditions for enzyme activity and how enzymes can be inhibited or enhanced.
How does temperature change the action of enzymes?
Temperature can affect enzyme activity because enzymes work best within specific temperature ranges. At low temperatures, enzyme activity decreases as the molecules move more slowly, decreasing the likelihood of enzyme-substrate collisions. At high temperatures, enzyme activity can be disrupted because the enzyme structure can become denatured, leading to a loss of function. Optimal temperature for enzyme activity varies depending on the specific enzyme.
Do enzymes work best in acidic conditions or alkaline conditions?
Enzymes generally work best within a specific pH range that is optimal for their function, and this can vary depending on the enzyme. Some enzymes work best in acidic conditions, while others work best in alkaline conditions. Maintaining the proper pH is important for enzyme activity.
What factors affect enzyme activity?
Temperature - too cold the enzyme will still work but slowly, too hot and the enzyme will become denatured . As temperature increases, the kinetic energy of the molecules increases so they move around more, meaning that there are more collisions between the enzymes and substrate molecules and therefore more reactions. pH - different types of enzymes work best in different pH environments. A change in pH interferes with the shape of the enzymes active site (where it bonds and reacts with substrate) and therefore does not fit the shape of the substrate as well so the enzyme is unable to work on the substrate. enzyme and substrate concentration - how many there is of each. Changing the concentrations of enzyme and substrate concentrations will affect the number of collisions between them and therefore the number of reactions. enzyme inhibitors - these are molecules which bind to enzymes, reducing their activity (many drugs are enzyme inhibitors). co-factors - these are chemical compounds which bind to enzymes and which are needed by the enzyme to work on substrate molecules. They are often called helper molecules.
What is the 4 step process of an enzyme at work?
Substrate binding: The enzyme binds to its substrate. Catalysis: The enzyme facilitates the conversion of the substrate into product. Product release: The enzyme releases the product of the reaction. Enzyme recycling: The enzyme returns to its original state to catalyze further reactions.
What does the refrigeation of food do with the way enzyme work?
Too cold for enzyme activity.
How does the enzyme subsrate help the enzyme work?
The substrate is the molecule that the enzyme acts upon, fitting into the enzyme's active site like a key fitting into a lock. This binding triggers a conformational change in the enzyme that allows it to catalyze the reaction more efficiently. The substrate provides the specific chemical groups and orientation needed for the enzyme to perform its function.
What are coemzymes?
These are either a vitamin or mineral that works with an enzyme. The enzyme doesn't work without it (them).
What enzyme speeds up a chemical reaction is known as?
All enzyme's are catalysts for certain chemical reactions. Each enzyme will only work with a certain substrate one analogy being that the enzyme is a key and the substrate is a keyhole, and each enzyme has a unique enzyme.
Some medicines work by blocking enzyme activity in pathogens These medicines are effective because they?
have a shape that fits into the enzyme
What can change the way an enzyme acts?
Enzyme activity is affected by other molecules, temperature, chemical environment (e.g., pH), and the concentration of substrate and enzyme. Activators are molecules that encourage enzyme activity, and inhibitors are enzymes that decrease enzyme activity. Sometimes a cofactor is necessary for the enzyme to work.
Who does the substrate work on enzyme action?
The substrate is the molecule on which the enzyme acts. It binds to the active site of the enzyme, leading to catalysis of the chemical reaction. The shape and chemical properties of the substrate are important in determining which enzyme can act on it.
When a molecule binds to an area of an enzyme that is not the active site and changes the shape of the enzyme so that it no longer can work this is called?
Denaturation
How does an activator work?
An activator is a molecule that binds to an enzyme and increases its activity, making the enzyme more efficient in catalyzing a specific reaction. Activators can do this by stabilizing the enzyme's active conformation or by helping the enzyme bind to its substrate more effectively.
After the reaction relaxed structure of enzyme can work again or not?
YES
Will an enzyme work if it denatures?
No if it is denatured, it can no longer preform its functions as an enzyme. You can also think of it as being a dead battery. No more use.
