PAPER COMPLETE QUESTIONS AND
CORRECT ANSWERS FULL SOLUTION
GUIDE

●● True or false: enzymes slow down chemical reactions to conserve
energy
Answer: false, they speed up (catalyze) chemical reactions


●● The term for metal ions that assist enzymes during the catalysis
reaction
Answer: cofactors


●● What is catabolism?
Answer: 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.
Answer: anabolism

, ●● An organism that obtains its energy (derives ATP) from photons of
light is called a __________________
Answer: phototrophic microorganism


●● An organism that derives its energy by removing electrons from
elemental sulfur would be classified as a ____________
Answer: Lithotroph


●● Describe the energy transfer process relative to both ADP and ATP
Answer: 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
Answer: oxidative phosphorylation


●● The catabolism of a single molecule of glucose goes through what
three transitions
Answer: The breakdown of glucose goes through 1. glycolysis 2.
fermentation or respiration and then 3. electron transport chain ETC
