Module 2 exam portage learning microbio 171 BIOD questions with
answers
True or false: metabolism is a controlled set of biochemical reactions that occur in living organisms
in order to maintain life. - ** VERIFIED ANSWERS **✔✔True
True or false: enzymes slow down chemical reactions to conserve energy - ** VERIFIED ANSWERS
**✔✔false, they speed up (catalyze) chemical reactions
The term for metal ions that assist enzymes during the catalysis reaction - ** VERIFIED ANSWERS
**✔✔cofactors
What is catabolism? - ** VERIFIED ANSWERS **✔✔The 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. - ** VERIFIED ANSWERS **✔✔anabolism
An organism that obtains its energy (derives ATP) from photons of light is called a
__________________ - ** VERIFIED ANSWERS **✔✔phototrophic microorganism
An organism that derives its energy by removing electrons from elemental sulfur would be classified
as a ____________ - ** VERIFIED ANSWERS **✔✔Lithotroph
Describe the energy transfer process relative to both ADP and ATP - ** VERIFIED ANSWERS
**✔✔ATP 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)
This phosphorylation process occurs in the mitochondria of chemotropic eukaryotes - ** VERIFIED
ANSWERS **✔✔oxidative phosphorylation
