MICROBIO 171 BIOD EXAM WITH
CORRECT QUESTIONS AND ANSWERS
2025
True or false: metabolism is a controlled set of biochemical reactions that occur in living
organisms in order to maintain life. - CORRECT-ANSWERSTrue
True or false: enzymes slow down chemical reactions to conserve energy - CORRECT-
ANSWERSfalse, they speed up (catalyze) chemical reactions
The term for metal ions that assist enzymes during the catalysis reaction - CORRECT-
ANSWERScofactors
What is catabolism? - CORRECT-ANSWERSThe process of breaking down larger
molecules into useful energy sources
Upon cellular injury, which metabolic process is involved during the growth and repair
phases of the cell. - CORRECT-ANSWERSanabolism
An organism that obtains its energy (derives ATP) from photons of light is called a
__________________ - CORRECT-ANSWERSphototrophic microorganism
An organism that derives its energy by removing electrons from elemental sulfur would
be classified as a ____________ - CORRECT-ANSWERSLithotroph
Describe the energy transfer process relative to both ADP and ATP - CORRECT-
ANSWERSATP has the energy (phosphate group) to donate, and ADP can accept energy
in the form of a phosphate group. Thus, ATP can be dephosphorylated (ATP-----> ADP +
Pi), while ADP can be dephosphorylated into ATP (ADP + Pi -----> ATP)
