PHYSICAL SCIENCE -BIOMOLECULES by RM

The picture presents the 4 types of Biomolecules and their elemental compositions.

What element is common in each type of biomolecule?

Give the name of the element

If biomolecules are carbon compounds, what type of compounds are they?

• Organic compounds

• Inorganic compounds

• Both organic and inorganic compounds

Answer explanation

Biomolecules are primarily composed of carbon, hydrogen, oxygen, and nitrogen, which classifies them as organic compounds. In contrast, inorganic compounds do not primarily contain carbon, making 'organic compounds' the correct choice.
