Question

d. activation energy

1. the bonding of calcium, phosphorus, and other elements produces mineral crystals that are found in bone. this is an example of a(n) __________ reaction.

a. catabolic
b. synthesis
c. decomposition
d. exchange

Explanation:

A synthesis reaction is one where two or more substances combine to form a more complex product. Here, calcium, phosphorus, and other elements combine to form mineral crystals in bone, which is a synthesis reaction. A catabolic reaction breaks down complex substances into simpler ones. A decomposition reaction is the breakdown of a single compound into two or more simpler substances. An exchange reaction involves the swapping of atoms or groups between reactants.

Answer:

B. synthesis
