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
