BIO 12 UNIT 1: STUDY NOTES

CARBOHYDRATES

Main Fuctions:

  • MONOMERS = Chemical energy in Cellular Respiration AND Building blocks for polymers
  • DIMERS = Short term energy stores, source of food (plants)
  • POLYMERS:
  1. Starch - Source of energy from ingesting foods such as plants [GLUCOSE]
  2. Glycogen - Stored energy in body (liver and muscles) [excess glucose --> long term energy]
  3. Cellulose - Structure for plants (cell wall), FIBRE (cannot be digested BUT helps keep us full and aids in making us excrete wastes)

Below is a link to an awesome video which shows our body and how we use fat and carbohydrates to function, specifically, athletes/sports, this was really interesting and thought provoking:
