What else can I help you with?
What is true of substrate?
It acts as a reactant. In a chemical reaction A substrate is a molecule that is reacted on by enzymes.
Is the enzymes affected temporarily or permanents?
That depends on the physical conditions. High temperatures, some substances or changes in pH cause enzymes to be permanently denatured. Very low temperatures and the presence of some inhibitors cause enzymes to be temporarily unable to catalyse reactions.
Why is it important that enzymes are not changed by the reaction that they control?
Enzymes need to remain unchanged by the reaction they catalyze in order to be reused multiple times, ensuring efficiency in the cell. If enzymes were changed during the reaction, they would not be available to catalyze subsequent reactions, which would slow down essential cellular processes.
What would happen if a reactant molecule with a different shape to the enzyme came into contact with the enzymes active site?
If a reactant molecule with a different shape than the enzyme comes into contact with the enzyme's active site, it is unlikely to bind effectively. Enzymes have specific active sites that accommodate only particular substrates, a concept known as the "lock and key" model. If the shape does not fit, the molecule will not trigger the catalytic activity of the enzyme, and no reaction will occur. This specificity ensures that enzymes catalyze only the intended biochemical reactions.
What is the difference in co enzyme and prosthetic group?
A coenzyme is a small, organic molecule that helps enzymes function by carrying chemical groups between enzymes, while a prosthetic group is a non-protein molecule covalently bound to a protein and is essential for its biological activity. In simpler terms, coenzymes are temporary helpers, while prosthetic groups are permanent attachments to proteins.
Do Enzymes raise the activation energy to break the bonds of reactant molecules?
Yes
When talking about enzymes where do reactant molecules bind and convert chemically to a product?
Active site

What chemical reduces the amount of activation energy needed for a reaction but is not a reactant?
Enzymes catalyze certain reactions.
What provides temporary storage of enzymes and waste products?
In cells, the vesicles provide temporary storage of food enzymes and waste products. A vesicle is formed when the cell membrane bulges out and pinches off.

What is a true of a substrate?
It acts as a reactant. In a chemical reaction A substrate is a molecule that is reacted on by enzymes.
What is the reactant for the enzyme peptidase?
The reactant for the enzyme peptidase is a peptide molecule. Peptidase enzymes catalyze the breakdown of peptide bonds within peptides or proteins, resulting in the release of amino acids.
One particular reactant can only produce one type of product regardless of the enzymes true of false?
False. Enzymes can catalyze multiple reactions, converting one reactant into multiple products. The specificity of an enzyme depends on its active site, which is tailored to bind to specific substrates and facilitate specific chemical reactions.
When talking about enzymes where do reactant molecules bind and convert chemically product?
In enzymes, reactant molecules bind to a specific region called the active site. This is where the chemical reaction takes place and the reactants are converted into products. The active site has a specific shape that matches the reactants, allowing for precise binding and conversion.
Is the enzymes affected temporarily or permanents?
That depends on the physical conditions. High temperatures, some substances or changes in pH cause enzymes to be permanently denatured. Very low temperatures and the presence of some inhibitors cause enzymes to be temporarily unable to catalyse reactions.
