4. Section 1 Glycolysis and Fermentation
Chapter 7
Objectives
Identify the two major steps of cellular respiration.
Describe the major events in glycolysis.
Compare lactic acid fermentation with alcoholic fermentation.
Calculate the efficiency of glycolysis.

5. Food contains usable energy stored in proteins, carbohydrates, and fats.

6. Harvesting Chemical Energy
Section 1 Glycolysis and Fermentation
Chapter 7
Harvesting Chemical Energy
Cellular respiration: when cells (autotrophs and heterotrophs) break down organic compounds to produce energy (ATP).

7. Products of cellular respiration are reactants in photosynthesis; Products of photosynthesis are reactants in cellular respiration.
C6H12O6 + H20CO2 + H2O + ATP
Cellular respiration can be divided into 2 stages: glycolysis and aerobic respiration.

Chapter 7
Glycolysis
takes place in the cytosol (cytoplasm) of cells.
1 glucose molecule is broken down to 2 pyruvic acid molecules.
2 ATP’s are produced for every glucose that undergoes glycolysis.

Lactic Acid Fermentation
an enzyme converts pyruvic acid into lactic acid without using O2.
Occurs in muscle cells during strenuous activity.

Alcoholic Fermentation
Some plants and unicellular organisms, such as yeast, use a process called alcoholic fermentation to convert pyruvic acid into ethyl alcohol and CO2.
