Class Assignments What By When • Chapter 2 Quiz 1 (big quiz) 9/20/06 • Calorimetry lab 9/20/06 • 1A only – W.S. 2.3 (DR/Quiz) 9/20/06 • Chapter 2 Quiz 2 9/22/06 • Read 38-42 9/22/06 • 3A only – Section Review p. 42 1-6 (1-5 in complete sentences) 9/21/06 • W.S. Carbon Compounds 9/26/06 • Due this class period • Due next class period • Due in the future
Postquiz Activities • Hand in quiz • Pick up W.S. “Carbon Compounds” from the lab stool • Adjustments • Multiple choice – #1 option (d) eliminate the word “only” • Do not answer the following: • Vocabulary Review # 2 & 3 • Multiple choice # 5 • Short answer # 1 & 4 • Correct homework • Read 38-42
Calorimetry • Complete the lab • Compare your answers (Total Kcal and Kcal/gram) with several other students • Answer #13 • Check your answer to #12 • Technical design has nothing to do with human error!
Chapter 2 Quiz 2 • Protein functions and examples • Amino acid parts • Peptide bond formation • Types of nucleic acids • Function of nucleic acids • Parts of nucleotides • Water Essay!
Chemical Reactions • Reactants Products • Activation energy – energy needed to start a chemical reaction • Enzymes – decrease the activation energy • Without enzymes most chemical reactions would not occur
Enzymes • Speed up reactions • Needed in small quantities • Reaction specific • Optimum pH • Varies on enzyme’s location • Ex. Stomach or mouth • Optimum Temperature • Most in body work best from 35-39˚C
Chemical Reactions • Active site • Substrate • Enzyme performance • pH • temperature
