Chapter 1: Store That Glucose & Chapter 2: Think Of Science

Metabolism: Mechanisms and Cause-Effect

  • Emphasizes mechanism: how digestion, absorption, and storage work
  • Key questions: how glucose is broken down? how glucose is stored? how fat is broken down, absorbed, and stored
  • Goals: bring blood glucose levels back to normal; store glucose as fuel in various tissues
  • Cause–effect relationships come from scientific experience

Glucose Handling: Breakdown, Transport, and Storage

  • Ingested nutrients are broken down to glucose
  • Pathway: digestion → absorption into bloodstream → transport to tissues → storage as glycogen in liver and muscle
  • Blood glucose is regulated to stay within normal range

Fat Metabolism and Storage

  • Breakdown of fat, absorption, and storage in the body (adipose tissue)

Blood Glucose Regulation

  • Mechanisms to restore homeostasis and store glucose as fuel in tissues

The Scientific Method as a Problem-Solving Approach

  • Observe phenomena
  • Generate a hypothesis
  • Design experiments to test the hypothesis

Analogy: Toddlers and Hypothesis Testing

  • When toddlers encounter a small object, they put it in their mouth; this mirrors hypothesis testing in science
