The number of molecules with which an enzyme reacts is the?
The number of molecules with which an enzyme reacts is typically one or more substrate molecules. Enzymes bind to their substrates at their active sites to catalyze chemical reactions. The number of substrate molecules that can interact with an enzyme at a given time depends on factors like enzyme concentration, substrate concentration, and the kinetics of the enzyme-substrate complex formation.
Are substrates and reactants the same?
No, substrates are the molecules upon which an enzyme acts to produce a reaction, while reactants are the starting materials that interact to undergo a chemical reaction. In some cases, the substrate itself might be a reactant in a given biochemical system, but not all reactants are substrates.

A given enzyme works on?
specific substrates to catalyze a biochemical reaction. Each enzyme has a specific substrate or group of substrates that it acts on, and the enzyme's active site is designed to bind to these substrates. This specificity ensures that the enzyme functions effectively in the body.
Do enzymes increase or decrease the rate of the reaction?
That depends on the signals given to the cell. If a cell receives a positive feedback, it makes more. If there are too much, a negative feedback is given to lower the amount. This is a way of controlling the enzyme balance in your body.
Why would you expect the rate of an enzyme-catalyzed reaction to increase proportionately to enzyme concentration given an unlimited supply of substrate?
No, since the reaction reaches a max rate depending on the speed of which the Enzyme bonds to the substrate and the speed at which the enzyme catalyzes the reaction to produce enzyme and product (shown below). E + S --> ES (E - enzyme, S - substrate, P - products) ES --> E + P Thus, if each reaction rate is not equal to each other, the rate of the overall reaction is not only proportional to both the concentration of enzyme and substrate.
In an enzyme catalyzed reaction what is the reactant called?
Generally in an enzyme-catalyzed reaction, the reactant is called the substrate, which in association with the enzyme forms the product.

What is the name given to the part of an enzyme where the substrate comes into contact it?
The active site is the specific part of an enzyme where the substrate binds and interacts with the enzyme. This is where the chemical reaction facilitated by the enzyme takes place.
Are substrates and reactants the same?
No, substrates are the molecules upon which an enzyme acts to produce a reaction, while reactants are the starting materials that interact to undergo a chemical reaction. In some cases, the substrate itself might be a reactant in a given biochemical system, but not all reactants are substrates.
Describe the change in the rate of reaction when the enzyme concentration is increased?
The increase of enzyme concentration increase the rate of reaction. Given a fixed amount of substrates, it means that the substrates will be digested faster as there are more enzymes to do the work. Substrate concentration, temperature, and pH value of the surrounding where the enzymes work on also affects the rate.
If more enzyme is used what happens to the amount of product per unit time?
If more enzyme is used, the amount of product per unit time generally increases because enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur. This allows more substrate molecules to be converted into product in a given time period.

How many substrates can an enzyme have?
An enzyme can have multiple substrates, as it can bind to more than one substrate molecule at a time. This binding can occur at the active site of the enzyme, where the substrates interact with the enzyme's catalytic residues to facilitate the chemical reaction. The specificity of the enzyme's active site determines which substrates can bind to the enzyme.
The effect of substrate concentration on the rate of reaction of h202 and catalase?
As the substrate concentration increases, so will the enzyme activity and hence there will be a quick reaction. however, only up to a certain point ( where, if you drew a graph of the reaction, the line will level off ) as all the active sites in the enzyme are occupied and the reaction cannot go any faster. Here more enzymes will be needed to speed up the reaction.
