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?

1. what word do we use to remember these six elements?
2. 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 special element all living things are made of.
2. Carbon is special because it can form four - covalent bonds, allowing for diverse and complex molecular structures.
3. The six elements found in almost all living things are carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), and sulfur (S).
4. The word 'CHONPS' is used to remember these six elements.
5. The four major macromolecules in living organisms and food examples:

• Proteins: Found in meat.
• Carbohydrates: Found in bread.
• Lipids: Found in butter.
• Nucleic acids: Found in all living cells and thus in many foods like fish.

Answer:

1. Carbon
2. It can form four - covalent bonds for complex structures.
3. Carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), sulfur (S)
4. CHONPS
5. Proteins - meat; Carbohydrates - bread; Lipids - butter; Nucleic acids - fish
