Does enzymes catalyze specific chemical reactions because the shape of their active site allows only certain substrate molecules to enter?
Yes.
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.
Are Enzymes specific to particular molecules?
Yes, enzymes are specific to particular molecules. Each enzyme is designed to catalyze a specific chemical reaction by recognizing and binding to specific molecules called substrates. This specificity is based on the shape and chemical properties of both the enzyme and the substrate.
Give 2 explanations for the fact that only certain substrate molecules will fit into this part of the enzyme molecule?
The active site of an enzyme is specifically shaped to accommodate only certain substrates based on their size, shape, and chemical properties. This specificity is important for the enzyme to carry out its function effectively. The active site of an enzyme may also have specific binding sites or pockets that interact with particular functional groups or chemical moieties on the substrate molecule, leading to selective substrate binding. This ensures that only the correct substrates can bind and be converted into products by the enzyme.
What do enzymes have to help them fit their substrates the molecules that attach to the enzymes?
They actually bind to a substrate as the term reactant is usually used in chemistry. They fit into what we call an active site just like a key will fit into a lock. The key must be the correct key or the reaction will not occur. So the enzyme is said to be specific for that substrate.
Substrate molecules bind to enzymes where?
The bind in the active site.
Does enzymes catalyze specific chemical reactions because the shape of their active site allows only certain substrate molecules to enter?
Yes.
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.
Why do enzymes usually only work on one substrate (or group of closely related substrates)?
Enzymes have specific active sites that bind to substrates in a complementary manner based on their shape and chemical properties. This specificity allows enzymes to interact with only certain substrates or closely related ones that can fit into their active sites. Any mismatches in shape or chemical properties may prevent effective binding and inhibit the enzyme's activity.
Explain the difference between substrate and active site?
The substrate is the molecule that binds to the active site of an enzyme. The active site is a region on the enzyme where the substrate binds and undergoes a chemical reaction. The specificity of the active site allows only certain substrates to bind and react with the enzyme.

How does an enzymes active site relate to it substrate?
The substrate binds to the active site.
If Pectinase only breaks down pectin and It has no effect in cellulose What term is used to describe this characteristic of enzymes?
Enzymes are substrate specific; meaning that their active site only allows for a certain substrate to bind - in this case, pectin, and the enzyme has no effect on any other biological molecules
Why must a molecule have a specific shape if it is to be a substrate of an enzyme?
Active sites of enzymes (where the substrates fit in) are substrate specific, and are complementary to the shape of the molecule (substrate). In this way, enzymes can only act on a specific substrate, since that is the only shape that it will accommodate in the active site.
