2016-2017 Curriculum Blueprint Grade: 10th Course Descriptions: Biology I and Honors Unit #2.1: Chemistry of Life/Macromolecules and Enzymes Quarter 1 Approximate Time: 8 days Unit Overview All living things are composed of four basic categories of macromolecules and share the same basic needs for life. Students need to relate the primary function of the carbohydrates to providing and storing energy. Also, students will relate the primary function of lipids to insulating, energy storage, and cell membrane make up and relate the primary function of nucleic acids (DNA and RNA) to cellular control by directing protein synthesis. Students will also need to identify enzymes as biological catalysts and explain the “lock and key” model as it relates to enzyme activity. Also, they will explain the effect of a catalyst on activation energy. Learning Goal Sample Essential Questions Students will be able to: Students will identify and/or describe the basic molecular structure of carbohydrates, lipids, proteins, and/or nucleic acids, and describe the primary functions of macromolecules in organisms. Students will explain how enzymes speed up the rate of a biochemical reaction by lowering the reaction’s activation energy. Students will identify and/or describe the effect of environmental factors on enzyme activity. Learning Scale Unit 2.1 How do the macromolecules of life differ from one another in structure and in function? Why are enzymes important and how do they work? Honors: Differentiate between monosaccharides, disaccharides and polysaccharides. What are the functions of carbohydrates in living things? What evidence do you have that show the relationship between the structure and function of enzymes? Focus Standards SC.912.L.18.1: Describe the basic molecular structures and primary functions of the four major categories of biological macromolecules. SC.912.L.18.11: Explain the role of enzymes as catalysts that lower the activation energy of biochemical reactions. Identify factors, such as pH and temperature Honors: SC.912.L.18.2 - Describe the important structural characteristics of monosaccharides, disaccharides, and polysaccharides and explain the functions of carbohydrates in living things. SC.912.L.18.3 - Describe the structures of fatty acids, triglycerides, phospholipids, and steroids. Explain the functions of lipids in living organisms. Identify some reactions that fatty acids undergo. Relate the structure and function of cell membranes. SC.912.L.18.4 - Describe the structures of proteins and amino acids. Explain the functions of proteins in living organisms. Identify some reactions that amino acids undergo. Relate the structure and function of enzymes. Unit End Product or Teaching Task Students will complete a written lab report for this unit, using what they have learned about macromolecules and the effect of enzymes on chemical reactions.

Reading Recursive Standards LAFS.910.RST.1.2 Determine the central ideas or conclusions of a text; trace the text’s explanation or depiction of a complex process, phenomenon, or concept; provide an accurate summary of the text. LAFS.910.WHST.3.9 Draw evidence from informational texts to support analysis reflection, and research. Text Support Labs, Activities and Tasks Holt McDougal Textbook Chapters 2.3-2.5 Macromolecule Snack Attack – CPALMS MEA lesson plan and lab. Macromolecules – Lesson Plans for proteins, carbohydrates, lipids, nucleic acids and Biochemistry. Current Research – Article on macromolecular science. Articles on Macromolecules – Article on types of biological macromolecules. Macromolecule Food Indicator Lab - students will complete a lab using indicators to determine which foods contain carbohydrates, lipids, proteins, and/or starches. The lab includes pre-lab questions, discussion, lab experimentation, post lab questions, results and conclusion. Enzymes in Action (5E lesson) - Students will predict, investigate, observe, and report on the effects that pH, concentration, and temperature have on catalase enzyme reactions. Students will conduct an experiment in which they will alter the pH, concentration, and temperature of the environment in which catalase enzyme reactions are taking place. Students will be able to describe how changes in these environmental conditions affect the action of the enzymes in living things. Honors: Got Lactase? - Students to observe and identify evidence of an enzyme's activity, lactase, and its function, and action on a substrate found in milk, lactose. 10th Grade Biology DRAFT
