Which of the following statements best
describes a function of an enzyme?
a.)enzymes are specialized proteins that
serve as catalysts.
b.)enzymes are carbohydrate-based
molecules found in all cells.
c.)the structure of enzymes is changed
during a chemical reaction.
d.)all enzymes work on all substrates.

The answer is A

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
