How does heating a enzyme affect its function?
For an enzyme to work it must bind to a specific substrate molecule, using a part of the enzyme molecule called the active site. To do this, the enzyme's active site and the substrate must have matching (complementary) shapes. The shape of an enzyme molecule depends on the exact way in which the molecule folds up. When enzymes are heated the weak bonds which hold the molecules in their precise shape are broken, and the enzyme molecule "unwinds" into a random shape. It can no longer bind with its substrate so it no longer has any activity. This "unwinding" of a protein molecule is called denaturation.
Give 2 explanations for the fact that only certain substrate molecules will fit into this part of the enzyme molecule?
A substrate molecule will only fit into the active site if it is a complimentary shape. Also the amino acids that make up an enzyme have positively and negatively charged chemical groups so in orderr for a substrate to fit its active site any electrical charges on the substrate molecule must not be repelled by like charges on the enzyme so the charged groups on the enzyme molecule and substrate molecule must attract one another
Is there any Procedure in enzyme and factors that affect enzyme activity?
Enzymes follow a specific procedure called "lock and key" model, where they bind to substrates to catalyze reactions. Factors that affect enzyme activity include temperature, pH, substrate concentration, and the presence of inhibitors or activators. These factors can alter the enzyme's structure, affecting its ability to bind to substrates and catalyze reactions effectively.
What does the shape of an enzyme have to do with how well the enzyme works?
The shape of an enzyme is crucial for its function because it determines the enzyme's specificity and ability to interact with its substrate. The specific shape allows the enzyme to bind to its substrate, facilitating the reaction. Any changes in the enzyme's shape can affect its ability to catalyze the reaction effectively.
How is protein structure involved in enzyme specificity?
Protein structure plays a key role in enzyme specificity by determining the shape and active site of the enzyme. The unique 3D structure of an enzyme's active site allows it to bind specific substrates with complementary shapes, leading to catalysis of specific chemical reactions. Any changes in the enzyme's structure can affect its ability to recognize and bind to its substrate, thereby impacting its specificity.
The specificity of an enzyme is due to its active siteThe active site is a shape only a certain?
substrate can fit into, due to complementary shapes and charges. This allows the enzyme to specifically catalyze a particular reaction. Any changes to the active site can impact the enzyme's ability to bind to its substrate and perform its function.
What is the definition of enzyme specificity?
each enzyme has a specific substrate to which it binds through a definite active site and any other enzyme can not bind to it

What is the name of the molecule that is the enzyme?
Typically, any macro-biomolecule whose name ends with the suffix -ase is an enzyme.
Why are enzymes three dimensional shape so important?
An enzyme's three dimension shape is important to the binding that occurs between the enzyme itself and its specific substrate, forming the enzyme-substrate complex. In order for the enzyme to create a reaction it is important that the shape of the enzyme binds the substrate to the active site where the chemical reaction occurs. One other thing to consider is the shape that the enzyme takes that allows only its specific substrate to bind and not any other molecule.
What helps an enzyme to bind to a specific active site?
What? Enzyme doent look for another enzmes active site! it just look for its substrate to bind at in its active site! This will in turn make it to form any by products or convert it from the actual state!

What is any enzyme that adds an inorganic phosphate group to another inorganic molecule called?
That enzyme is called a kinase. Kinases catalyze the transfer of a phosphate group from adenosine triphosphate (ATP) to another molecule.

What determines the shape of an enzymes active site?
The shape of an enzyme's active site is determined by its amino acid sequence, which folds into a specific three-dimensional conformation. This unique shape allows the enzyme to interact selectively with its specific substrate, forming an enzyme-substrate complex for catalysis to occur. Any alterations to the active site's shape can affect the enzyme's function.
Why does denaturing effect enzyme reactions?
If you denature an enzyme, you do not kill it because it was never alive, but you shut it down. It cannot work any longer and therefore it cannot speed up the reaction. The overall reaction will be slower because there are less enzymes.
