What type of structure do proteins which act as enzymes possess?
Proteins that act as enzymes typically have a specific three-dimensional structure called an active site. This active site is where the enzyme binds to its target molecule, known as the substrate, to catalyze a chemical reaction. The structure of the active site allows enzymes to be highly specific in their function.
Which two levels of protein structure principally determine the active site of an enzyme?
The primary and secondary levels of protein structure determine the active site of an enzyme. The specific arrangement of amino acids in the active site, influenced by both the primary sequence and secondary structures such as alpha helices and beta sheets, is critical for enzyme-substrate interactions.
What effect do temperature and pH have on enzyme controlled reactions?
enzyme require an optimum temperature and ph level to be active. temperature at which most enzymes are active is around 35-40 degree celcius. above this temperature the enzyme loses it globular structure and thus the substrate will not be able to bind with it. some enzymes are active in alkali ph while others are active in acidic temperature. but most of the enzymes are active in neutral ph and this helps to maintain its globular structure.
What do enzymes have to help them fit their substrates the molecules that attach to the enzyme?
Enzymes are proteins that have a very specific structure. The region on the surface of an enzyme that is responsible for binding and converting the subtract into the product is called the active site.
Is an enzyme a structural protein or functional protein?
Yes, enzymes are proteins and it is their sequence of amino acids (primary structure) that determines what kind of an enzyme it is and makes all the enzymes unique and it is the tertiary structure of enzymes that maintains their shape and give rise to the unique active site. When an enzyme is denatured, it loses its tertiary structure and therefore its shape.
What do enzymes have to help them fit their substrate?
Enzymes are proteins that have a very specific structure. The region on the surface of an enzyme that is responsible for binding and converting the subtract into the product is called the active site.
Substrate molecules bind to enzymes where?
The bind in the active site.
Difference between enzyme and active site?
enzymes are from the testicular area and are in sperm. The active sight is the creation of enzymes in the scrotum
What does enzymes functions depend on?
The function of an enzyme is dependent on the shape of the enzyme. The structure and shape determines what the enzyme can do.
What effects does acid have on ezyme?
Acids can denature enzymes and make them less active or completely inactive. Denaturation causes a change in the three-dimensional structure of an enzyme which can affect the function of the enzyme.
How enzyme structure makes an enzyme very specific?
Enzymes are proteins, which are made up of amino acids. Each enzyme has a different sequence of amino acids and changing even one amino acid will mean that the tertiary structure of the enzyme will be lost and so will it's active site. As enzymes are substrate specific, only a certain substrate will bind to its active site, due to its amino acid sequence determining the shape of the active site.
What are roles performed by sodium sulfide and ethanol in catalase and amylase?
Sodium sulfide is often used as a reducing agent in biochemical reactions involving enzymes like catalase and amylase. It helps to maintain the enzyme's active conformation by preventing the formation of disulfide bonds that could disrupt its structure. Ethanol, on the other hand, is commonly used as a denaturant to disrupt enzyme activity by altering the enzyme's tertiary structure. In the context of catalase and amylase, ethanol can be used to inhibit or deactivate the enzymes by disrupting their active sites.
