_______________________ is a process that uses light energy to drive an electron transport chain to make ATP.

Why do human cells require oxygen? Select all relevant statements.

a. To carry out glycolysis

b. To carry out fermentation

c. To carry out cellular respiration

d. To oxidize fats

e. To carry out substrate-level phosphorylation

f. To carry out oxidative phosphorylation

g. To carry out photophosphorylation

The photo shows an organism growing in glucose fermentation broth. What can you conclude about this specimen with regard to its ability (or lack thereof) to ferment the sugar sucrose? Explain your answer.

The _______________________ test detects if an organism can convert hydrogen peroxide to water and oxygen. The test result is usually _______________________ in anaerobic microbes and usually _______________________ in aerobic microbes. You know the test is positive by _______________________.

_______________________ is a process that relies on a phosphorylated intermediate to directly convert ADP to ATP.

Draw and then fill out a Venn diagram (see sample version here) that compares and contrasts anaerobic respiration to aerobic respiration. The middle section of the diagram is where you should list the features these processes have in common. Include as many details as possible in this diagram to make this a useful exercise.
