Question

macromolecules

1. which special element are all living things made of? ____________
2. what makes this element so special?
3. which six elements are found in almost all living things?
4. what word do we use to remember these six elements? ____________
5. list the four major compounds (macromolecules) found in living organisms and give one example of where you could find each compound in food. hint: protein is one of these compounds.

Explanation:

1. Carbon is the key element in all living things as it can form diverse and complex molecules due to its ability to form four covalent bonds.
2. Carbon's unique bonding properties allow it to create long - chain polymers and complex 3 - D structures essential for life processes.
3. The six elements are carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), and sulfur (S).
4. The word is CHONPS.
5. The four major macromolecules are proteins (found in meats, beans), carbohydrates (found in bread, rice), lipids (found in oils, butter), and nucleic acids (found in all living cells).

Answer:

1. Carbon
2. It can form four covalent bonds and complex molecules.
3. Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, Sulfur
4. CHONPS
5. Proteins (meats, beans); Carbohydrates (bread, rice); Lipids (oils, butter); Nucleic acids (all living cells)
