Essential minerals of the intercellular cement?

• A. Biotin
• B. Zinc, copper
• C. Intercellular cement
• D. Sand cracks

Answer: (B)

The intercellular cement, the extracellular matrix that binds cells together in connective tissue, relies on proper collagen and elastin strengthening. Copper is essential here because it is a cofactor for lysyl oxidase, the enzyme that cross-links collagen and elastin, giving the tissue its tensile strength. Without sufficient copper, these cross-links don’t form effectively, weakening the intercellular cement.

Zinc also plays a crucial role by supporting enzymes involved in collagen synthesis and remodeling, contributing to the production and maintenance of the matrix, and aiding mineralization processes in bone and dentin. Adequate zinc ensures robust matrix formation and tissue integrity; deficiency can compromise the strength of the connective tissue.

Biotin is a vitamin, not a mineral, so it doesn’t fit the category of minerals essential to the intercellular cement. The other non-mineral options describe components or concepts rather than minerals, so they don’t address the question.

Thus, zinc and copper are the essential minerals for the intercellular cement.
