Catalysts affect the chemical reactions that take place within the body. what function do catalysts perform in chemical reactions?
a. catalysts slow down the rate of chemical reactions.
b. catalysts are always formed by chemical reactions.
c. catalysts are used up during a chemical reaction.
d. catalysts lower the activation energy of a chemical reaction

I think the best answer for this is D.  Catalysts lower the activation energy of a chemical reaction. Catalyst is a substance that speeds a chemical reaction. It is not consumed as the reaction proceeds. A catalyst offers a new route for faster reaction.

Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. Enzymes are proteins that act as catalysts in biochemical reactions. Common types of catalysts include enzymes, acid-base catalysts, and heterogeneous (or surface) catalysts

Once mass defect is known, nuclear binding energy can be calculated by converting that mass to energy by using E=mc2. Mass must be in units of kg. Once this energy, which is a quantity of joules for one nucleus, is known, it can be scaled into per-nucleon and per-mole quantities.
