Question

1. what are organic compounds?
2. what are the four organic compounds (macromolecules) found in all living things?

a.
b.
c.
d.

1. complete the table below:

macromolecule

elements

monomers

functions

food examples

Explanation:

1. Organic compounds are chemical compounds that contain carbon - hydrogen bonds. They are essential for life processes.
2. The four organic compounds (macromolecules) in all living things are lipids, proteins, carbohydrates, and nucleic acids. Lipids are energy - storage molecules and components of cell membranes. Proteins have diverse functions such as catalyzing reactions, providing structural support, and transporting substances. Carbohydrates are a source of energy and also play a role in cell - to - cell recognition. Nucleic acids (DNA and RNA) store and transmit genetic information.

3.

Macromolecule	Elements	Monomers	Functions	Food Examples
Proteins	Carbon, Hydrogen, Oxygen, Nitrogen (sometimes Sulfur)	Amino acids	Catalysis, structure, transport, immune function	Meat, beans
Carbohydrates	Carbon, Hydrogen, Oxygen	Monosaccharides	Energy source, structural support in plants	Bread, fruits
Nucleic Acids	Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus	Nucleotides	Store and transmit genetic information	All living cells (as DNA and RNA are present in cells)

Answer:

1. Chemical compounds with carbon - hydrogen bonds.
2. a. Lipids

b. Proteins
c. Carbohydrates
d. Nucleic acids
