What statement best describes what happens during the catalytic cycle?
a the enzyme breaks the substrate apart to prepare for the reaction.
b the enzyme positions the substrate to increase access during a reaction.
c the substrate uses enzyme energy to start the reaction.
d the active site releases the substrate and replaces it with an inhibitor.

B. The enzyme positions the substrate to increase access during a reaction.

Explanation:

The catalytic cycle is, in chemistry, a reaction mechanism caused by an enzyme, and this method is characterized by sequences of chemical reactions.

In the catalytic cycle, the first reaction involves the binding of one or more substrates by the enzyme, and the interaction of the elements provides the chemical reactions. The enzyme positions the substrate to increase access during a reaction. In this cycle, the activation energy exceeds the repulsion force, being responsible for the collisions and breakdowns of the reagents. Using catalysts, the equilibrium of reactions is achieved faster.

this disease is :

* endemic (present in a defined area that is a village)

* a bacterial infection (treated with antibiotic)

* communicable by contact (by the hands)

manu-porterage is the most common mode of transmission, it transmits germs from one individual to another via the hands. this concerns infections of exogenous origin.

endemic disease, or endemic disease, refers to a disease that is constantly present in a given population, often tied to a specific geographic origin, as opposed to a pandemic that is not a sporadic disease.

antibiotics are molecules that have the property of killing (bactericidal) or limiting the spread (bacteriostatic) of bacteria.
