I'm working on a microbiology question and need an explanation and answer to help me learn.

1. What is a fermentation pathway? List the characteristics that define them.
2. In what ways are fermentation pathways similar to aerobic respiration pathways for catabolism
of glucose?
3. Describe 3 different fermentation pathways that are found in prokaryotic cells.
4. Describe the pathways involved in lactic acid fermentation and alcohol fermentation.
5. Briefly summarize how lipids and proteins can be used to produce energy in cells.
6. Compare and contrast each of the following nutritional patterns found in microorganisms:
photoautotrophs, photoheterotrophs, chemoautotrophs, chemoheterotrophs. Give an example
of an organism that falls into each category.
