1 Which of the following best describes, in general, how organisms benefit from enzymes?
A They speed up chemical reactions for the organisms.
B Enzymes maintain constant temperature in the organism.
C They are responsible for reproduction in organisms.
D Enzymes transfer genetic information between organisms.

A

Explanation:

Enzymes in an organism speed up chemical reactions by lowering the activation energy (energy needed for reactants to come together and react)

A

Explanation:                                                                                                                    The enzyme speeds up the reaction by lowering the activation energy needed for the reaction to start

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
