What is enzyme?
Enzyme is a biological catalyst, which is proteinin nature, and can speed up the rate of a chemical reaction, without it being chemically changedat the end of the reaction. How do enzymes work? Enzymes work by lowering the activation energyof a reaction.
What determines an enzyme’s function?
An enzyme’s function is determined by its shape, and each enzyme has one specific function. What determines an enzyme’s function, and how many functions does one enzyme have? An enzyme’s function is determined by its shape, and each enzyme has one specific function.
What happens to the enzymes when they are heated up?
The enzymes will lose their bond structure and fall apart. The enzymes will require less energy to function than at 70 °C. The enzymes will not increase the rate of reactions as much as they would at 70 °C. Q. What will most likely happen if an appropriate enzyme is added to a chemical reaction?
Why are enzymes so specific in shape?
Each enzyme molecule is a globular protein which has a specific 3-dimensional shape including its active site The active site of an enzyme only binds to a substrate molecule with a complementary shape, resulting in enzymes being very specific
en·zyme | ˈen-ˌzīm . : any of numerous complex proteins that are produced by living cells and catalyze specific biochemical reactions at body temperatures.
What are some examples of enzymes in the body?
Examples of specific enzymes There are thousands of enzymes in the human body, here are just a few examples: Lipases – a group of enzymes that help digest fats in the gut. Amylase – helps change starches into sugars.
What are the enzymes that break down food called?
Digestive enzymes help break down the foods we eat and convert them into energy. An example of these types of enzymes is the enzyme amylase, which breaks down starch into simple sugars. The three most important digestive enzymes are protease, amylase, and lipase, which digest protein, carbohydrate, and fat, respectively.
What is an enzyme that cannot function without a specific molecule?
Some enzymes cannot function unless they have a specific non-protein molecule attached to them. These are called cofactors. For instance, carbonic anhydrase, an enzyme that helps maintain the pH of the body, cannot function unless it is attached to a zinc ion.
