How many of the glycolysis enzyme molecules does a cell have?
It has 2 ATP molecules.
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.
What enzyme builds mRNA molecules bases on the code in DNA?
The enzyme is RNA polymerase.
Which enzyme will break down starch into smaller monosaccharide molecules?
Alpha amylase is the enzyme that breaks down starch into it's individual glucose monosaccharide molecules.
In a denatured enzyme what would happen to the enzyme?
they dont do anything because they are unable to bond with a substrate.
Why does increase enzymes concentration promote enzyme activity?
Increasing enzyme concentration increases the number of collisions between the enzyme molecules and the substrate molecules. This increases the number of successful collisions and the number of enzyme-substrate complexes. Therefore the reaction rate is increased as well and enzyme activity is promoted.
Differentiate extra and intracellular enzymes?
An extracellular enzyme is one which reacts outside of the cell. An intracellular enzyme is one which reacts inside of the cell.
What are three that ways to control enzymes?
One way to control an enzyme is by altering the number of enzyme molecules. Two other ways are by altering the enzyme activity and compartmentalization.
What factors affect enzyme activity?
Temperature - too cold the enzyme will still work but slowly, too hot and the enzyme will become denatured . As temperature increases, the kinetic energy of the molecules increases so they move around more, meaning that there are more collisions between the enzymes and substrate molecules and therefore more reactions. pH - different types of enzymes work best in different pH environments. A change in pH interferes with the shape of the enzymes active site (where it bonds and reacts with substrate) and therefore does not fit the shape of the substrate as well so the enzyme is unable to work on the substrate. enzyme and substrate concentration - how many there is of each. Changing the concentrations of enzyme and substrate concentrations will affect the number of collisions between them and therefore the number of reactions. enzyme inhibitors - these are molecules which bind to enzymes, reducing their activity (many drugs are enzyme inhibitors). co-factors - these are chemical compounds which bind to enzymes and which are needed by the enzyme to work on substrate molecules. They are often called helper molecules.
IS FAT A HORMONE OR ENZYME?
No it is not a hormone or an enzyme. It is a type of molecules
What is the Difference between intracellular enzyme and extracellular enzyme?
An intracellular enzyme reacts inside the cell body while the extracellular enzyme affects the outside part of the cell.
What enzyme converts the glucose into bigger molecules?
Starch is an enzyme that converts the glucose into bigger molecules. Starch is proteins and fat.

Forms when pyruvic acid reacts with enzyme coa?
acetyl CoA
What does the enzyme ATPsynthetatse do?
ATPynthetatse is an enzyme that rejoins phosphates back to the adenosine in ATP molecules.
What enzyme builds mRNA molecules bases on the code in DNA?
The enzyme is RNA polymerase.
