What are enzymes?
Click to flip
Enzymes are biological catalysts that speed up chemical reactions in living organisms.
Click to flip
What is the active site of an enzyme?
Click to flip
The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.
Click to flip
How do enzymes work at a molecular level?
Click to flip
Enzymes lower the activation energy needed for a chemical reaction to occur, thereby increasing the rate of the reaction.
Click to flip
Are enzymes used up in a reaction?
Click to flip
No, enzymes are not consumed in the reaction; they are recycled to catalyze additional reactions.
Click to flip
What is enzyme specificity?
Click to flip
Enzyme specificity refers to the tendency of an enzyme to catalyze only one particular reaction or a set of closely related reactions.
Click to flip
Can enzymes function outside living cells?
Click to flip
Yes, enzymes can function outside living cells, as they can catalyze reactions in vitro.
Click to flip
What is substrate concentration in relation to enzymes?
Click to flip
Substrate concentration is the amount of substrate present that can be turned into a product by enzymes.
Click to flip
What happens when a substrate enters an enzyme’s active site?
Click to flip
The enzyme undergoes a conformational change to form an enzyme-substrate complex, facilitating the reaction.
Click to flip
What is the enzyme-substrate complex?
Click to flip
It is a temporary complex formed when an enzyme binds to its substrate molecule(s).
Click to flip
Give an example of an enzyme and its substrate.
Click to flip
An example is the enzyme amylase, which acts on the substrate starch.
