Flashcards in Chapter 7: Fermentation and Anaerobic Respiration Deck (6):
1

-electrons carried by NADH are transferred to an organic acceptor molecule
-NAD+ accepts electrons in reaction 6 o glycolysis
-glycolysis continue to supply ATP by substrate-level phosphorylation

fermentation

2

-converts pyruvate into lactate
-occurs in some bacteria, plant tissues, skeletal muscle
-used to make buttermilk, yogurt, dill pickles

lactate fermentation

3

-converts pyruvate into ethyl alcohol and CO2
-occurs in some plant tissues, invertebrates, protists, bacteria, and single-celled fungi such as yeasts
-used to make bread and alcoholic beverages

alcoholic fermentation

4

fermentation is the only source of ATP for bacteria and fungi that lack enzymes to carry out oxidative phosphorylation

strict anaerobes

5

can switch between fermentation and full oxidative pathways, depending on the oxygen supply

facultative anaerobes

6

they have an absolute requirement for oxygen to survive and are unable to live solely by fermentations
