Principal Learning Outcome 1
Describe the molecular details of the conversion of the body’s main energy sources (carbohydrates, lipids, proteins) into energy.
After this lecture, you should be able to:
- Describe the goal of metabolism in the human body and name its main energy sources.
- Give the definition of metabolic regulation, and explain its three main components (energy storage expenditure, and delivery).
- Explain the chemical concepts of polarity, osmosis, and reduction-oxidation reactions in context of human metabolism.
- Identify reducing agents and oxidizing agents in a chemical reaction.
- Give the molecular structure of carbohydrates and lipids (and proteins) and name basic properties in context of human (energy) metabolism.
- Explain the difference between catabolic and anabolic reactions in human metabolism.
- Give examples of energy carrying intermediates used in human metabolism and relate these to the measures of energy status in cells.
- Explain the difference in substrate storage and delivery between carbohydrates and lipids in human metabolism.
- Give the main pathways of the metabolic (energy) flux in the human body
- Locate and explain the subprocesses of the metabolic energy pathways:
- general: TCA cycle, electron transport chain
- glucose: Glycolysis, gluconeogenesis, pentose phosphate pathway, lactate and pyruvate pathways, glycogen pathways
- lipids: beta-oxidation, fatty acid synthesis, ketone body pathways, carnitine shuttle, lipolysis, lipogenesis
- amino acids: amino acid catabolism, urea cycle, amino acid synthesis
