Question

for each macromolecule group, describe their function and discuss two examples of molecules that belong to each of the groups

1. carbohydrates -
2. lipids -
3. protein -
4. nucleic acids -

Explanation:

1. Carbohydrates: Function - main energy source for cells. Examples - glucose (used directly for energy in cellular respiration), starch (storage form in plants).
2. Lipids: Function - energy storage, component of cell membranes. Examples - triglycerides (energy - storing fat), phospholipids (major part of cell membrane structure).
3. Proteins: Function - various roles including enzyme catalysis, structural support. Examples - amylase (enzyme that breaks down starch), collagen (provides structural support in connective tissues).
4. Nucleic acids: Function - store and transmit genetic information. Examples - DNA (stores genetic code), RNA (involved in protein synthesis).

Answer:

1. Function: Main energy source for cells. Examples: Glucose, Starch.
2. Function: Energy storage, component of cell membranes. Examples: Triglycerides, Phospholipids.
3. Function: Various roles including enzyme catalysis, structural support. Examples: Amylase, Collagen.
4. Function: Store and transmit genetic information. Examples: DNA, RNA.
