Cellular Respiration: Work with your group members to research your respiration event. When you
are finished, you will teach your peers about your event while they teach you about their event. At the end of
class you should have an understanding of the entire respiration process.
Respiration Background: When you consume food, the molecules are broken down in the smaller
molecules such as glucose. During respiration, your cells break down these “simple” molecules even further
to produce the energy that is needed for your cells to carry out different functions.
The chemical equation for respiration is:
C6H12O6 + 6O2
Glucose
oxygen
6CO2
+ H2O + energy
carbon dioxide water
Respiration events: There are three events that take place during respiration.
1. Glycolysis
2. Krebs Cycle
3. Electron transport chain
Group 1: Glycolysis
Where in the cell does glycolysis happen?:
The Steps to glycolysis are: In the space below, generate a flow chart which diagrams the steps of glycolysis.
Group 2: The Krebs Cycle
Where in the cell does the Krebs cycle take place?
What are the steps of the Krebs cycle?: In the space below, generate a flow chart which diagrams the steps of
the Krebs cycle.
Group 3: The Electron Transport Chain
Where in the cell does the electron transport chain take place?
What are the steps to the electron transport chain? In the space below, generate a flow chart which diagrams
the steps of the electron transport chain.
Homework Question: What happens during fermentation? Be sure to address both alcoholic
fermentation and lactic-acid fermentation.
