What happens to an enzyme after it catalyzes a chemical reaction?
Enzymes are not used up in a chemical reaction. Usually, the enzyme will "reset" and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction. Initially, the enzyme has a particular shape. Something happens to the enzyme (usually a shape change, called a conformation change, brought on by the presence of two or more chemical reactants), and the enzyme catalyzes the reaction. After the reaction is catalyzed, the product is released, and the enzyme can "relax." This means it goes back to its normal shape, ready to do it all over again.
How do enzyme cofactors and coenzymes differ?
both need to be present in the enzyme for the reaction to take place but the substrate undergoes a physical transformation while the cofactor remains the same.
When the active site of an enzyme is continuously filled and the maximum enzyme rate has been reached what happens if more substrates are added to the reaction?
Nothing. The Vmax remains constant and the graph produced at this point would show your curve flattening at a plateau.
What happens when an enzyme is denatured?
When an enzyme is denatured the active site which allows it to catalyze reactions is destroyed, rendering the enzyme useless. This process is irreversible but the remains are recycled to form new enzymes.
What happens to a phytoplankter that remains below its compensation depth?
Carbonic anhydrase (if present) converts HCO3 to CO2 so they can continue to fix carbon.
What happens to the rate of enzyme concentration when you increase substrate concentration?
The rate of enzyme reaction is increased when the substrate concentration is also increased. However, when it reaches the maximum velocity of reaction, the reaction rate remains constant.
What happens to the enzymes after the substrate reacts?
It is either used again (many enzymes are used multiple times before broken down) or is broken down.
What happens when increasing the substrate concentration when there is less substrate than enzyme?
Dunno. But this is pretty cool. But if i search the question, i obvioudly don't know it, so why would i be given an optionto answer it?
What happens or doesn't happen to an enzyme at the end of an enzymatic reaction?
The enzyme still remains and can be used again for another reaction.
What remains when water is evaporated after a neutralization reaction?
If the water is evaporated after a neutralization reaction, what remains?
When an atom undergoes oxidation what happens to the number of neutrons?
Oxidation is a chemial reaction; the atom and the number of neutrons remains unchanged.
What is a substrate in the context of enzyme reaction?
Enzyme-substrate specificity means that a substrate can fit into an enzyme similar to a key fitting into a lock. The active site of the enzyme is what determines its specificity. An enzyme can hence catalyze a reaction with a specific substrate, such as amylase catalyzing starch molecules. During these reactions, the substrate is held in a precise optimum position to create and break bonds, catalyzing the molecule.
How much catalyst remains at the end of a catalysed reaction?
All the catalyst remains as it is not incorporated into the reaction products, it just speeds up the reaction time.
How does increasing substrate concentration affect the rate of enzyme action when the enzyme concentration remains constant?
It doesn't
How does increasing enzyme concentration affect the rate of enzyme action when substrate concentration remains constant?
It doesn't
A variable that remains the same?
Constant or controlled variable.
What is a controlled vaiable?
A controlled variable is one that remains the same throughout the experiment, i.e., it is not changed
