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.
Why do enzymes have an active site?
The structure of an enzymes and its active site determine which substrates will work for the enzyme. This is called the lock and key method. The active site is the lock and the substrate is the key.
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.
Substrate molecules bind to enzymes where?
The bind in the active site.
What determines the shape of an enzymes active site?
The active site is part of an enzyme where substrates bind and undergo a chemical reaction.

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.
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.
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
When a protein such as an enzyme is subjected to too much heat?
The enzyme denatures, the internal bonds break. This means that the active site changes shape. This is because the arrangement of the secondary structures change After overheating an enzyme it is unusable
Give an example of the relationship between structure and function?
One example of the relationship between structure and function is found in enzymes as their function is dependent upon its structure. Enzymes are catalytic proteins that speed up a reaction without being consumed. Their protein structure enables them to recognize their substrates, even among isomers, thus allowing them to catalyze very specific reactions. The interactions between a protein's primary structure, its amino acid sequence, determine its secondary structure of hydrogen bonded alpha and beta pleated sheets. The side chains of the amino acids help determine the next superimposed structure, the tertiary structure and the quaternary structure if the protein has one. A protein's conformation enables it to form an active site whose shape is compatible with that of the substrate. Once the substrate enters the active site, the enzyme's structure is altered as induced fit moves the active site's chemical groups into positions that enhance their ability to catalyze the chemical reaction, thus improving the enzyme's function. An enzyme's structure is so closely correlated to its function that even a slight change in a protein's primary structure can affect its conformation and ability to function. For example, although noncompetitive inhibitors bind to the enzyme away from its active site, they alter the enzyme's conformation so that the active site no longer has the right structure to bind with the substrates, preventing it from functioning correctly.
