There is a lot of drawing in this course. You are expected to keep an art kit (pencils, pens, erasers, markers, etc) in your bags so that you can sketch when the lesson calls for it.
You should (theoretically) have your lockers today. If that is the case, I will distribute textbooks and workbooks. Leave your textbook at home for reference, but bring the workbook every single day.
Chapter 2 PowerPoint
Sections 2.1, 2.2 & 2.3
2.1: Molecules to Metabolism
1. Draw molecular diagrams of glucose, ribose, a saturated fatty acid and a general amino acid.

3. Explain the difference between condensation and hydrolysis reactions.
4. Identify biomolecules such as sugars, lipids and amino acids based on their structures.
1. Compare the thermal properties of water with those of methane.
2. List and describe the essential properties of water.
3. Explain the necessity of hydrogen bonding.
4. Explain the solubility of water and its relationship to transporting molecules in organisms.
2.3: Carbohydrates & Lipids
1. Describe the structures of saccharides and provide examples.
2. Explain the differences between saturated and unsaturated fats.
3. Apply the structure of a triglyceride to its role in the human diet.
2. Complete Lesson 2.1: Molecules to Metabolism.
Mission 1: Breaking It All Down. Carbon atoms can form four covalent bonds, which allows a diversity of stable compounds to exist. As a result, carbon-containing organic molecules can form chains, rings, and branched chains.
Homework: In this PowerPoint, complete Tasks #1, 2 and 3. This is your first assignment.
Mission 2: Well, It's What We're Made Of, Right?
Water is the medium of life. Understanding why it is so important requires understanding of its structure. There are two hydrogen ions sharing electrons with an oxygen ion. Sharing of electrons results in a covalent bond. The water molecule is polar, meaning that it has a net charge on one end (the oxygen end). As a result, water can interact with itself and other molecules in different ways. Water has many different properties which makes it so important in living organisms.
Homework: Complete Tasks #4, 5 and 6 in the PowerPoint.
Outline condensation and hydrolysis reactions using a different example for each.
Outline the effect of temperature and substrate concentration on the activity of enzymes.
Outline the role of hydrolysis in the relationships between monosaccharides, disaccharides and polysaccharides.
Explain the importance of enzymes to human digestion.
State four elements that are needed by living organisms, other than carbon, hydrogen and oxygen, giving one role of each.
Compare the use of carbohydrates and lipids in energy storage.
Explain how the properties of water are significant to living organisms.
