Biochemistry
Age 12-14: Concept 1 - Semester 1: Unit 4

This unit covers the scientific field of Biochemistry: the study of chemistry related to the functioning of living organisms. You will first learn about the types of molecules present in organisms, such as carbohydrates and proteins, which are known as biomolecules. The unit goes in-depth to explain how the biological processes of an organism are kept in equilibrium and what occurs when that biochemistry is disrupted. In addition, you will explore the ways in which the immune system works in fighting off pathogens and other conditions that affect the normal functioning of a living organism. This unit also discusses food intake and health and provides you with the opportunity to keep a journal that tracks your daily intake of food.

For the final project of this unit, you will use your food journal to analyze and compare your own food intake with a healthy diet. This will allow you to create a recommendation sheet for dietary changes based on your discoveries.

Summary of Skills

Moving Beyond the Page is based on state and national standards. These standards are covered in this unit.
  • Describe factors that determine the effects a chemical has on a living organism including exposure, potency, and dose and the resultant concentration of chemical in the organism. (Science)
  • Describe factors that determine the effects a chemical has on a living organism including: immune response, individual susceptibility, and possible treatments to eliminate or reduce effects. (Science)
  • Describe risks and benefits of chemicals. (Science)
  • Identify evidence that some substances may contribute to human health conditions including autoimmune disease. (Science)
  • Identify feedback mechanisms that maintain equilibrium of systems such as body temperature (fever, hypothermia, homeostasis) and water pressure (plants: wilting; diffusion/osmosis). (Science)
  • Know that carbon, because of its ability to combine in many ways with itself and other elements, has a central role in the chemistry of living organisms. (Science)
  • Know that living organisms are made of molecules consisting largely of carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. (Science)
  • Know that living organisms have many different kinds of molecules: inorganic molecules, e.g. water, salt, and others; and organic, macromolecules, e.g. carbohydrates, fats, proteins, and DNA. (Science)
  • Understand that principles of chemistry underlie the functioning of biological systems. (Science)
