Study Notes
Animal Physiology
- The study of animal physiology dates back to 420 B.C.
- It explores how animals function and interact with their environment.
Types of Nutrition
-
Autotrophic nutrition: Organisms that obtain energy from sunlight.
- Examples include plants and bacteria.
-
Heterotrophic nutrition: Organisms that obtain energy by consuming other organisms.
- Humans are heterotrophic.
Types of Digestion
-
Intracellular digestion: Occurs within food vacuoles inside cells.
- The digested food diffuses into the cytoplasm.
-
Extracellular digestion: Occurs outside of cells, in the gut lumen.
- Found in higher animals.
- Digested materials are absorbed into cells.
Building Blocks of Life
-
Lipid (Fat) synthesis:
- When a glycerol molecule combines with three fatty acid molecules.
- Requires the removal of three water molecules.
- Called a condensation reaction.
- The ester linkage forms between the glycerol and the fatty acids.
-
Lipid (Fat) breakdown:
- A triglyceride is broken down into one glycerol molecule and three fatty acid molecules.
- Requires the addition of three water molecules.
- Called a hydrolysis reaction.
-
Protein synthesis:
- Large macromolecules formed from carbon, hydrogen, oxygen, nitrogen, and sulfur.
- Composed of amino acids linked together.
- Amino acids are joined by a peptide bond.
- Requires the removal of a water molecule (condensation reaction).
-
Dipeptide: Two amino acids joined together by a peptide bond.
- The carboxyl group of one amino acid bonds to the amino group of the other amino acid.
Interesting Note
- The Mosquito is an example of a sanguivorous organism.
- This means it is a heterotrophic organism that feeds on blood.
