Answer:
Enzyme: A biomolecule that speed up the rate of chemical reactions without being used up.
Substrate: A substance or chemical that enter the chemical reaction and is being converted into a new substance (product).
Competitive enzyme inhibition: Inhibition of enzyme's activity by binding of inhibitor to substrate binding site of the enzyme.
Explanation:
Enzymes are the biomolecules that serve to increase the rate of reactions by lowering down the required activation energy. The enzyme is never used up during reactions.
Substrates are the chemicals that undergo a chemical change and produce products.
For example, Glucose is the substrate for hexokinase enzyme and is converted into glucose 6 phosphate (the product).
When the inhibitor competes with the substrate for the binding site on the enzyme and does not allow the substrate to bind to the enzyme, the process is called competitive enzyme inhibition. It can be overcome by increasing the concentration of substrate in the system.
The Story of an Hour Theme of Freedom and Confinement. At first, freedom seems like a terrible thing to Mrs. Mallard, who's restricted in lots of ways: through her marriage, by her bad heart, and even inside her home, which she doesn't leave during "The Story of an Hour."
When you run it makes your heart pump blood faster ,when your pulse is up it means you veins are flowing blood and your blood has good circulation
A memory B cell is kinda of how it sounds it has a memory of what your body has fought before such as a virus and can stimulate a response quicker then the first time you encountered it.
If you lack memory B cells your body doesn't built up the same immune response when you come into contact with the virus again.
"Vaccination would prevent further disease" Incorrect, a vaccine lets you build up memory cells to combat the disease if you lack them you cannot build up a defense.
"Vaccination would not prevent further disease" Correct, a vaccine can be a dead version of a virus or parts of a virus that shows your body what to respond to quickly in the future. If you body cannot make memory b cells it wouldn't help to use a vaccine. Your body wouldn't keep a memory of it being bad.
"You would not produce antibodies" Even if your body does not remember a particular virus it does produce antibodies to combat it just not as quick or efficiantly as something it has come into contact with before and produced memory cells.
"You would over produce histamine" Incorrect, different process for that histamine.
