How pro duct concentration affect enzyme activity?
Increasing substrate concentration can initially increase enzyme activity as more substrate molecules are available for the enzyme to bind to. However, at a certain point, the enzyme becomes saturated with substrate molecules and enzyme activity levels off. Very high substrate concentrations can also lead to competitive inhibition or product inhibition which can inhibit enzyme activity.
Is it true that after the product of an enzyme-catalyzed reaction leavesthe active site the enzyme can no longer react with more substrate?
No, after the product of an enzyme-catalyzed reaction leaves the active site, the enzyme can still react with more substrate to continue catalyzing the reaction. The enzyme is not altered or used up in the reaction, so it can continue to bind to and catalyze additional substrate molecules.
During enzme-catalyzed actions substrate is a synonym for?
In enzyme-catalyzed reactions, the term "substrate" is synonymous with the molecule or molecules that the enzyme acts upon to produce a reaction. It is the specific substance upon which an enzyme acts to produce a product.
What is a substrate .?
A substrate molecule hydrogen bonds to the active site on an enzyme and causes it to distort. The distortion stresses a bond in the substrate, causing it to break into two product molecules. These are released by the enzyme and drift away.
What name is given to the molecules made in an enzyme controlled reaction?
The molecules made in an enzyme-controlled reaction are usually referred to as products. These products are the result of the substrate molecules being transformed by the enzyme during the reaction.
What is a mechanism by which a single hormone molecule can trigger the production of millions of molecules of a metabolic product?
enzyme
What is the enzyme product for carbohydrase?
The enzyme product for carbohydrase is the breakdown of carbohydrates and sugars into simpler molecules like glucose. This process helps in the digestion of starches and sugars in the body for energy production.

Very high substrate concentrations can also lead to competitive inhibition or product inhibition which can inhibit enzyme activity.
What is catalytic constant?
The catalytic constant, or turnover number, is a measure of how many substrate molecules an enzyme can convert into product per unit time when the enzyme is fully saturated with substrate. It is expressed in units of molecules of substrate converted per unit time per enzyme molecule. A higher catalytic constant indicates a faster enzyme reaction rate.
What is Kcat?
Kcat is the catalytic efficiency of an enzyme, representing how many substrate molecules an enzyme can convert to product per unit time at a particular enzyme concentration. It is a measure of the enzyme's turnover rate.
What happens to the reaction rate as the enzyme concentration is increased?
As enzyme concentration increases, the reaction rate usually increases because there are more enzyme molecules available to catalyze the reaction. This is because enzymes can bind to more substrate molecules simultaneously, leading to a greater frequency of successful collisions and faster conversion to product. However, once all substrate molecules are bound to enzymes (enzyme saturation), further increases in enzyme concentration will not significantly affect the reaction rate.
An excess of end-product molecules alters the shape of the first enzyme in the pathway and shuts off that metabolic pathway?
Feedback Inhibition

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.
What is a substrate .?
A substrate molecule hydrogen bonds to the active site on an enzyme and causes it to distort. The distortion stresses a bond in the substrate, causing it to break into two product molecules. These are released by the enzyme and drift away.
