CELLULAR RESPIRATION OVERVIEW
9/17/18
PG 38
DO NOW▸What are the two products of
photosynthesis?
▸Where does photosynthesis occur?
▸Why is photosynthesis important?
▸ I will stamp HW and summaries
AGENDA▸Overview of cellular respiration
▸ Illustrative Summary
▸ POGIL: Cellular Respiration
CELLULAR RESPIRATIONPAGE 39 (CORNELL NOTES TITLE)
IF YOU RUN OUT OF SPACE, USE PAGE 41
HOW TO MAKE ATP (ADENOSINE TRIPHOSPHATE)
PAGE 39
CELLULAR RESPIRATION▸Makes ATP from sugars and other carbon-
based molecules
▸Aerobic process - requires oxygen
▸Occurs in the mitochondria
PAGE 39
CELLULAR RESPIRATION EQUATION
PAGE 39
3 STAGES IN CELLULAR RESPIRATION▸Glycolysis (outside mitochondria)
▸Makes a few ATP and NADH
▸Citric Acid Cycle (aka Krebs cycle)
▸Makes NADH, FADH2, and a few ATP
▸ Electron Transport Chain
▸Makes most of the ATP
PAGE 39
GLYCOLYSIS▸Goal 1: split glucose into two pyruvate (pyruvic acid)
molecules. Needs 2 ATP
▸Makes 4 ATP
▸ 2 ATP TOTAL made
▸Goal 2: make NADH (carries e-)
PAGE 39
CITRIC ACID CYCLE (AKA KREBS CYCLE)▸Goal: use pyruvate to make NADH and
FADH2
PAGE 39
ELECTRON TRANSPORT CHAIN▸Goal: use NADH and FADH2 to make as
much ATP as possible
▸Needs O2
ELECTRON TRANSPORT CHAIN

CELLULAR RESPIRATION STEPS
ILLUSTRATIVE SUMMARYPAGE 40
EACH TERM MUST HAVE AN ILLUSTRATION
FOLLOW DIRECTIONS
DO NOW▸Read through “Is Yeast Alive?” and
annotate the first paragraph
▸Answer the 2 questions on the first page
▸Read through the procedures quietly
▸ I will stamp HW and summaries
IS YEAST ALIVE?
LAB ROLES
IS YEAST ALIVE▸ Facilitator - keep group on task
▸ Spokesperson - obtain all necessary materials
▸ Process Analyst - ensure table is following directions
▸Quality control - ensure that table is working together
IS YEAST ALIVE‣Water vs. Water + Sugar‣You only need 1 timer per table ‣Do NOT fool around. No horseplay. No
loud noises.‣You will be kicked out of the room and
you will receive a zero for the lab‣Follow directions carefully‣Clean up properly when you have finished
gathering data‣Answer questions at the end of the lab
CLEAN UP‣Throw away the balloons in the trashcan. ‣Pour the yeast solutions down the drain
and rinse the bottles. ‣Place the CLEANED plastic bottles in the
recycling bin. ‣Wipe your table with your Clorox wipe.
HOMEWORKFINISH THE LAB QUESTIONS
PG 38
DO NOW (UNDER THE PREVIOUS DO NOW)▸What are the products of cellular
respiration
▸What are the major steps of cellular respiration?
▸ Take out the lab
LAB DISCUSSION
‣What gas was being released? ‣Is yeast alive? ‣Where did the carbon from CO2 come
from?
POGIL
POGIL (PROCESS ORIENTED GUIDED INQUIRY LEARNING)
‣Facilitator‣Spokesperson‣Quality Control‣Process Analyst
ROLE
FACILITATOR
‣Group begins promptly ‣Group stays on task, progresses through
activity in a timely manner ‣All members of the group are participating
ROLE
SPOKESPERSON
‣Seeks group input before consulting teacher or other groups
‣All group members feel satisfied that their issues have been addressed
‣Articulates questions and responses well
‣AT THE END OF EVERY PAGE, RAISE YOUR HAND SO I CAN CHECK YOUR WORK
ROLE
QUALITY CONTROL
‣Any individual sample collected should accurately demonstrate the groups’ understanding
‣Regularly checks that group members’ answers are consistent (not necessarily identical)
‣Encourages individuals to make sure answers are thorough (i.e. showing work)
ROLE
PROCESS ANALYST‣Analyst reports to group regarding group
performance at least one time during the activity as well as at the end
‣Analyst provides insightful and positive feedback on how the group is working
‣Analyst completes the process questions report if directed
TASK
POGIL (PROCESS ORIENTED GUIDED INQUIRY LEARNING)
‣Task: complete #1-22 in 30 minutes
QUICK GROUP DISCUSSION‣ Spokesperson
‣What is a big takeaway for your group? Give specific examples
‣Process Analyst‣What is the strength of your group?
Give an example‣What is an area of growth for your
team? Why?
