What switchs on enzyme activity while what can switch off or reduce enzyme activity?
activators; inhibitors
What do activators and inhibitors help regulate?
enzyme activity within the metabolic pathways
What can change the way an enzyme acts?
Enzyme activity is affected by other molecules, temperature, chemical environment (e.g., pH), and the concentration of substrate and enzyme. Activators are molecules that encourage enzyme activity, and inhibitors are enzymes that decrease enzyme activity. Sometimes a cofactor is necessary for the enzyme to work.
Can the presence of inhibitors or activitors affect enzyme activity?
yes, enzymes can be inhibited by other enzymes.
Are chemical mechanisms that start a reaction. Inhibitors Activators Centrioles Vacuoles?
You think probable to activators for enzymes.

Why are calcium good for clotting?
calcium act as enzyme activators in clotting without it either there would be no clotting or delayed clotting
What factors affect the rate of enzyme activity?
-Heat, temperature, &pHtemperature, pH level, concentration of enzyme, concentration of substrate( my sec.1 science book)
What are 4 factors that can regulate enzyme activity?
pH, temperature, concentration of substrate, incubation period
When was The Activators created?
The Activators was created in 2009.
What kinds of chemicals might you add to try to speed up the action of an enzyme or to inhibit its action?
The type of chemicals that speed up the action of an enzyme are called activators. Inhibitors, meanwhile, slow down the action of enzymes.
Can the presence of inhibitors or activitors affect enzyme activity?
yes, enzymes can be inhibited by other enzymes.
What is role of metal ion in enzyme catalysis?
On each surface of enzyme there are detachable cofactor (non-protein portin of enzyme) called activators. Activators are metal ions.Enzymes are proteins and literally fold into a specific 3d structure, to make space for an active site (also called activators). Active site has a shape that fits with specific substrate molecules.The enzyme and substrate form a temporary enzyme-substrate complex.Enzymes are flexible structures.When enzyme and substrate bind together, the shape of enzyme molecule undergoes slight change.This produces strain in chemical bond in the substrate molecules and as a result these bonds break and bonds are formed. These stresses encourage a link between two substrstes leading to the formation of a different molecule.As the result of the chemicl interactions within the active sites a new chemical compound is formed. The new chemical compound is called product.This product is released from the active site, the enzyme assumes its orignal shape and is free to work again.
What is the function of dehydrogenase?
dehydrogenase is an enzyme which transfers hydrogen ions from a substrate to an activator.Example are activators are NAD+ and FAD+.
What is the difference between apoenzyme and holoenzyme?
Enzymes are proteins that catalyze (i.e., increase the rates of) chemical reactions, Coenzymes are small organic molecules that transport chemical group. Inhibitors are activators or molecules that increase or decrease enzyme activity. Apoenzyme is a protein component of an enzyme, to which the coenzyme attaches to form an active enzyme where as holoenzyme is an active, complex enzyme consisting of an apoenzyme and a coenzyme.
