Ms. Lyon Honors Chapter 6 http://biology.clc.uc.edu/courses/bio104/atp.htm ( song) http://www.eduref.org/cgi‐bin/printlessons.cgi/Virtual/Lessons/Science/Biology/BIO0202.html Chapter 6 Cellular Respiration Focus: to see how cells take food energy and change it into ATP Preexposure: read p. chapter 6 (89-105) Priming: Instructor may provide Big Picture as priming Focus Questions: 6.1 Define and compare the processes of breathing and cellular respiration. 6.2 Describe the overall chemical equation for cellular respiration. Compare the efficiency of this process in cells to the
efficiency of a gasoline engine. 6.3 Explain how the human body uses its daily supply of ATP. 6.4 Explain how the energy in a glucose molecule is released during cellular respiration. 6.5 Explain how redox reactions are used in cellular respiration. 6.6-6.7 Describe the roles of the electron transport chain and chemiosmosis in cellular respiration. 6.7 Compare the process of substrate-level phosphorylation to chemiosmosis. 6.8 Describe the cellular regions where glycolysis, Krebs cycle, and the electron transport chain occur. 6.8-6.14 Compare the reactants, products, and energy yield of the three stages of respiration. Also indicate where each
process occurs in the cell. 6.15 Compare the reactants, products, and energy yield of alcoholic and lactic acid fermentation. Distinguish between
strict anaerobes and facultative anaerobes. 6.16 Explain how polysaccharides, proteins, and fats are broken down to yield ATP. 6.17 Explain how food molecules are used in biosynthesis. 6.18 Describe the fundamental relationship between respiration and photosynthesis. How We Will Do This Lesson: CHECK OFF STEPS AS YOU GO FIRST: Please fill in this chart to organize your ideas. We will go over this as big picture before you start building. CONCEPT ILLUSTRATION Catabolism Fermentation Cellular respiration Store energy of catabolism Phosphorylation Oxidation Reduction Application of LEO GER to respiration NAD‐‐‐‐‐‐‐NADH I will provide big picture before you start Activity: Cellular Repsiration We will make a 3 D mitochondria using candies and poster paper. We will represent the mitochondrial membrane with string. We will represent what is going on inside the mitochondria with colored candies. Get a sheet of poster paper. Look here to see where we are in the cell. http://wps.prenhall.com/wps/media/objects/376/385232/Media‐Portfolio/chapter_21/text_images/FG21_04.JPG STEP ONE (I instructor to draw an general picture on the board so you leave enough space for everything.) look at page 95 fig.6.8 Put a BIG circle of string around the edge of the poster paper. ( glue it down) (LEAVE some room to represent the cytosol of the cell on top and on the sides of the poster paper) Label this cell membrane. Move into the mitochondria slightly and glue down more string going all around inside. (These two strings represent the outer and inner membrane. Look at fig 6.8 for help) Starting on the left side of your mitochondria move inward towards the right. Place another piece of circular string 2/3 of the paper on the right (don’t go past the middle inside). STOP Label outside the entire mitochondria the cytosol. Label inner and outer mitochondria membrane. Label mitochondria matrix. Label (inside) the inner circle inside the mitochondria Citric Acid Cycle (KREBS CYCLE) . STEP TWO Go tp page 101 fir 6.13 for the correct placement of the things. On the inner mitochondrial membrane (the two sets of string defining the membrane) please add cytochromes and ATP synthase to your drawing using marshmallows and glue.(this goes toeards the right side of the mitochondria) NOTE: you place cytochromes and ATP Synthase on the inner membrane!!!!! Make sure the ATP synthase is facing the correct direction. BUILD IT CORRECTLY STOP: (look at fig. 6.8) Label the cytoplasm with the term glycolysis, the first part of mitochondria( just as you enter it) with the term acetyl COA stage, the inside of the inner membrane with the term krebs cycle, and the part with the marshmallows with the term electron transport stage. Now read your book and decide why we used these labels STOP: Get organized as to where you are so far Now please make a color scheme……(You have m&m’s, or jelly beans to use or something) one color for # of Carbon, one color for NADH, one color for ATP, one color for hydrogen, one for electrons in ETS. Code your poster. Now at each subdivision on the poster,( except for ETS) please make the 3 columns, label them INTO the Rx, OUT of the RX, WHAT is happening (see instructor on board) You will be filling in your charts following this color code. STOP: As a class lets get caught up so we are all on the same page: Together we will now illustrate glycolysis. Do you have your colors? Let’s start with carbon. Meet with your team and tell me the name of the carbons that go into glycolysis. How many C? glue down that many m&m or whatever to represent C on the INTO side of the chart. Now how many come out of the reaction? Keep gluing as the instructor walks you through ATP and NADH. Now you continue to do all the stages. When you get to ETS, you will not have a 3 column to fill in. You need to push electrons and hydrogen through the ET chain. Ask the instructor if you are having problems. http://www.sp.uconn.edu/~terry/Common/respiration.html this is a nice interactive we can use when we present. Closure Packet; Review Packet
