Define Metabolism. Name and describe the two types of metabolic reactions that occur in our bodies. Which one is endergonic and which one is exergonic? Based on your descriptions of the two types of reactions does this labeling of exergonic or endergonic make sense? Why?

Expert Solution

Metabolism can be defined as a series of chemical reactions taking place within the body which is involved in energy transfers required for sustenance of life. Endergonic reaction - Here energy is absorbed from the surroundings. The bonds being formed are weaker than the bonds being broken. Exergonic reaction - Here energy is released in the surroundings. The bonds being formed are stronger than the bonds being broken. Usually anabolic reactions (where building up occurs) use up energy and are energonic. e.g - Formation of peptide bonds between amino acids. Catabolic reactions on the other hand release energy and are exergonic. e.g - Conversion of glucose during respiration to produce carbon dioxide and water.
