Relation to Syllabus

The information presented on this page is designed to be used by teachers to show the links between the material in this trail and the NSW HSC Chemistry (Stage 6) Syllabus. Relevant excerpts of the Syllabus are shown on this page and a copy of the full Syllabus may be downloaded from the Board of Studies website in PDF format. Additionally, teachers are advised to take note of the Board Bulletins as they contain up-to-the-minute important information.


9.7 Option - The Biochemistry of Movement

Contextual Outline

Modern athletes are more aware of diet than previous generations, because more is known about the chemistry of the substances in their diet. A increased understanding of the nature of the biochemical reactions involved in muscular contraction leads to a better and more informed selection of foods.

Biochemists interested in sports performance will continue to seek natural methods of improving performance by paying close attention to the chains of enzyme catalysed reactions occurring in the cytosol of the cell as well as within the mitochondria. This module provides an overview of the two extremes of exercise and allows discussion of possible directions of further research.


2. Carbohydrates are an important part of an athlete's diet. Students learn to:
  • identify that carbohydrates are composed of carbon, hydrogen and oxygen according to the formula Cn(H2O)n
  • explain that humans store carbohydrates as glycogen granules in our muscles and liver
  • identify glucose as the monomer which forms the polymer glycogen and describe the process of bond formation between the glucose molecules which produces the polymer
Students:
  • choose resources and perform first-hand investigations to compare the structures of glycogen and glucose from diagrams or models
  • use available evidence and process information from secondary sources to analyse the structures of glucose and glycogen molecules and account for their solubility in water
  • solve problems, choose equipment and perform a first-hand investigation to observe the combustion of glucose and gather first-hand data to calculate the heat of combustion per mole
