What is the relationship between an enzyme and a reactant molecule?

Answer 1

Activation energy is the energy that must be provided to make a reaction take place. The enzyme helps speed up the reaction by lowering the activation energy making the reaction occur at a lower temperature than it would without an enzyme.

So when a substrate binds to the active site of an enzyme, the shape of its molecule is lsighty changed. this makes it easier to change into a product. AS student.
It lowers it.

Answer 2

Enzymes bind to reactant molecules, or substrates, at their active site. The active site of the enzyme allows for specific interactions with the substrate, facilitating the chemical reaction to occur. Enzymes lower the activation energy needed for the reaction to proceed, thus increasing the rate of the reaction.

Answer 3

Enzymes act as catalysts for chemical reactions that converts sets of reactants called substrates into specific products. The active site of the enzyme binds to the substrate, creating an enzymatic reaction. Side chains from a few of the amino acids that make up the active site catalyzes the substrate conversion to product and it leaves the active site. Once that product leaves, the enzyme is free to bind with another substrate and continue the process.

Answer 4

They work like a lock and key. Each enzyme is designed to fit into a specific substrate. Well let me start by explaining what an enzyme is and then a subtrate. An enzyme is a protein that speeds up the chemical reaction in a living organism. An enzyme acts as a catalyst for specific chemical reactions, converting a specific set of reactants called substrates into specific products.

In an enzymatic reaction, the substrate binds to the active site of the enzyme. Side chains (R groups) of a few of the amino acids that make up the active site, catalyze the conversion of substrate, to proudct, then the product exits the active site. The enzyme is then free to to take another subtrate molecule into it's active site. Some enzymes are faster than others and enzymes like other catalysts, emerge from the reaction in their original form. Most metabolic reactions are reversible and an enzyme can catalyze both the forward and backward reactions. The enzyme always catalyzes in the the reaction in the direction of equilibrum.

So, the relationship between enzyme and substrate is: the rate at which a particular amount of enzyme converts substrate to product is partly a function of the initial concentration of the subtrate. The more subtrate molecules available the more frequently the access the active sites of the enzyme molecules. At some point the concentration of substrate will be high enough that all enzyme molecules have their acitve sites engaged. So, as soon as the product exits an active site, another subtrate molecule enters, and this subtrate concentration the enzyme is said to be called saturated. When an enzyme population is saturated, the only way to increase the rate of product formation is to add more enzymes. Cells sometimes do this by making more enzyme molecules.

Answer 5

the relationship is temporary

Answer 6

temporary association
