Microbiology Quiz 12 (BIO 210)

WEEK 12, QUIZ 12

Where does the largest amount of each of these products get formed?

==Glycolysis:== Precursor metabolites

==Electron Transport Chain:== ATP

==Krebs Cycle:== Reduced carrier molecules (NADH, FADH2)

Which of the following statements is TRUE regarding the location of these metabolic pathways?

In bacterial cells, ==glycolysis and the Krebs cycle occur in the same place==

Where might the hydrogens (H) from a glucose molecule ultimately end up at the end of ==AEROBIC== ==cellular respiration== performed by bacteria?

H2O

If the membrane where the electron transport chain is located is NOT selectively permeable, ATP can still be made using the ATP synthase enzyme.

FALSE: If the membrane is not selectively permeable, then the H+ can diffuse back across the membrane without having to travel through the ATP synthase, and without H+ moving through it, the ATP synthase enzyme is shut off so no ATP will be made.

Which of the following would you expect to decompose the FASTEST? (Based on the activity in "dead thing by a tree")

banana in unsealed bag with soil or banana in unsealed bag without soil
