Unit 1: Biochemistry
SC.912.L.18.1 Describe the basic molecular structures and primary functions of the four major categories of biological macromolecules.
· Students will generally be able to Identify the basic molecular structure and describe the primary function of macromolecule in organisms
Reminder: Students should recognize all organic macromolecules and their functions.
1. Complete the table below.
| Macromolecule | Functions | Elements | Structure
| Carbohydrate | Provides energy | Carbon, hydrogen, oxygen | CH2O
| Lipid | Storage compounds | Carbon, hydrogen, and oxygen | Phospholipids
| Protein | Transport materials throughout your body | Carbon, hydrogen, oxygen, and nitrogen | Sequences of amino acids
| Nucleic Acid | Carry code for the making of proteins | Phosphorous and Nitrogen | DNA and RNA
SC.912.L.18.11 Explain the role of enzymes as catalysts that lower the activation energy
· Students will generally be able to state how enzymes speed up the rate of a biochemical reaction and identify the effects of environmental factors on enzyme activity
2. What are enzymes and how do they affect activation energy in a chemical reaction?
Enzymes speed up reactions by lowering activation energy.
SC.912.L.1.18.12 Discuss the special properties of water that contribute to Earth’s suitability as an environment for life: cohesive behavior, ability to moderate temperature, expansion upon freezing and versatility as a solvent.
· Students will generally be able to summarize the properties of water and relate how these properties make water essential for life on earth
3. Describe each of the following properties of water and provide an example for how it helps to support life on Earth (be specific).
· Cohesion - sticking together of alike molecules, such as water molecule
· Adhesion - the force of attraction between unlike molecules
· Specific heat capacity - the amount of energy required to raise the temperature of one gram of a substance
· Expansion upon freezing - water reaches a maximum density at about 4°C causes bodies of water to freeze on the top first
· Universal solvent
4. What is the relationship between the properties of water and transpiration that takes place in plants?

Unit 2: Cell Structure & Function/ Cellular Transport
SC.912.L.14.1 Describe the scientific theory of cells (cell theory) and relate the history of its discovery to the process of science.
5. What are the 3 components of the cell theory?
SC.912.L.14.4 Review the parts (structure and function) of the compound microscope
6. Label the following parts of a compound microscope and describe each of their functions.
