Microbiology Notes 3: Bacterial Energy Metabolism (making Atp)

Question 1

How do bacteria make atp

Answer 1

Oxygen usage

1. Aerobic bacteria
   (Need oxygen to make atp)
2. Anaerobic bacteria
   (Make atp without oxygen and use other molecules. Can’t use oxygen)
3. Factullative aerobic bacteria
   (Use oxygen when present but don’t need)

Question 2

How do bacteria make atp (#2)

Answer 2

Food source

1. Heterotrophic bacteria
   (Use organic food, ex glucose)
2. Litheltrophic bacteria
   (Use inorganic materials for food source, ex iron, sulfates, plastics)
3. Photographic bacteria
   (Use photosynthesis, happens in thylakoids)
