Monomers of proteins, carbs and lipids, and nucleic acids -
Answer: Carbohydrates: Monomers are monosaccharides/sugar
(glucose, galactose, fructose)
Proteins: Monomers are amino acids
Lipids: Monomers are fatty acids and glycerol
Nucleic Acids: Monomers are nucleotides
What is metabolism? - Answer: The sum of all chemical
reactions in the body
Anabolism - Answer: -Endergonic reaction
,-Energy is consumed as the reaction takes place.
-Build up!
-Create bonds between small molecules to make large
molecules (polymers)
-Example: protein synthesis
Catabolism - Answer: -Exergonic reaction
-Energy is released as reaction takes place
-Break down
-Break bonds in large molecules (polymers) to make small
molecules
-Example: digestion of starch to glucose
What are the types of macronutrients? (essay) - Answer: -Water
-Carbohydrates
-Proteins
-Lipids
What is the importance of each macronutrient? (essay) -
Answer: -Water: Solvent, coolant, involved in metabolic
reactions, waste dilution, supports blood volume/pressure.
, -Carbohydrates: Fuel, component in nucleic acids, ATP,
glycoproteins, glycolipids.
-Proteins: Support muscle contraction, cell structure, enzymes,
transport, hormones, oxygen transport, blood factors,
immunity, neuromodulators, buffers, emergency fuel.
-Lipids: Fuel, structure of plasma membranes and myelin
sheaths, involved in hormones, insulation, vitamin absorption,
vitamin D synthesis, blood clotting.
What is the source of each macronutrient? (essay) - Answer: -
Water: Present in drinks, fruits, vegetables, and produced during
metabolism.
-Carbohydrates: starch, sugar, cellulose, glucose. Found in
grains, legumes, fruits, vegetables. Complex carbs in whole
grains, simple carbs in fruits and dairy.
-Proteins: eggs, meat, peroxidase, nuts, cheese. Come from
animal (meat, dairy) and plant sources (legumes, nuts). Animal
proteins are complete; plant proteins may need combining.
