Osteoid-producing osteoblasts must rely on this organelle to produce primary structures leading to the formation of collagen and calcium-binding proteins.
a. peroxisomes
b. ribosomes
c. mitochondria
d. centrioles

The correct answer is option b. "Ribosomes".

Explanation:

Osteoid-producing osteoblast must rely on ribosomes to produce the primary structures leading to the formation of collagen and calcium-binding proteins. Ribosomes are organelles whose main function is to produce proteins, therefore, this organelle is the one that must function in order to osteoid-producing osteoblast could produce the proteins that it needs.

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
