Notes 7.1 – Glycolysis
Cell Respiration Part 1Page 131
Standards
CLE 3210.3.3 Investigate the relationship between the processes of photosynthesis and cellular respiration.SPI 3210.3.3 Compare and contrast photosynthesis and cellular respiration in terms of energy transformation.
Objectives
Identify the reactants and products of GlycolysisEvaluate situations when a cell must use anaerobic vs. aerobic respirationSummarize the major events in Glycolysis
Find a Partner
Dogs
Tell your partner what making a bond means in terms of energy?
Ducks
Tell your partner what breaking a bond means in terms of energy?
With your Partner:
Look up the definition of “cellular respiration” Determine if both plant and animal cells can perform cellular respiration.
Give evidence to support your answer.
Electron Transport Chain
Overview of Cell Respiration
Equation:
Three Main Parts: --
Glycolysis – Happens in cytosol
Krebs Cycle– Happens in mitochondria
C6H12O6 + O2 CO2 + H2O + ATP (energy)
Glycolysis
Reactants:
Products:
Glucose, 2 ATP, NAD+
Pyruvate – moves to Kreb Cycle H2O – becomes part of cytosol 4 ATP – used by cell NADH – moves to electron transport chain
With your partner
Think about the following question:
If Glycolysis makes 2 molecules of water,why do we need to drink water?
Net Gain
What if I told you that if you put 50 cents into a vending machine, it would give you a dollar?
Would you put in 50 cents?Why?What would be your profit?Profit (Net gain) = amount gained - amount invested
Net Gain_____ ATP are required to start Glycolysis
_____ ATP are produced
______ = the net gain of energy produced by Glycolysis

What happens to Pyruvate?
Two possible paths:
Pyruvate
Aerobic Respiration
(mitochondria)
Fermentation (cytosol)
Lots of ATP
Some ATP
With your Partner
Look in the book and list 2 situations where fermentation is used instead of aerobic respiration.
