CELLS 7.2 Fermentation- Pre AP Biology Study Notes – New Syllabus.
LEARNING OBJECTIVE
CELLS 7.2(a) Explain the biological importance of fermentation.
CELLS 7.2(b) Describe how energy transfer in the cell occurs under anaerobic conditions in consumers.
Key Concepts:
- CELLS 7.2.1 Organisms have processes for the transfer of energy under completely anaerobic conditions.
a. Fermentation allows for production of two molecules of ATP during glycolysis if no oxygen is present.
b. Two common forms of fermentation are alcohol and lactic acid.
1. Yeast uses alcohol fermentation to transfer energy from glucose and to release CO₂ as a byproduct. This is an economically important process because it is used to make many food products.
2. Bacterial and animal cells are able to utilize lactic acid fermentation to transfer energy from glucose in the absence of oxygen.
