BIO 1201 EXAM 2 PRACTICE PAPER 2026
TESTED QUESTIONS AND SOLUTIONS
GRADED A+
◉ exergonic
Answer: metabolic reactions that release energy
◉ DNA synthesis
Answer: example of endergonic reaction
◉ hydrolysis of ATP to ADP and Pi, glucose + O2 to CO2 and water
(respiration)
Answer: two examples of exergonic reactions
◉ catabolism, ATP, cell work, ADP+Pi
Answer: ATP cycle: energy from ____ --> ____ --> energy for ____ -->
____ -->
◉ coupled reactions
Answer: when an unfavorable (endergonic) rxn is linked to a very
favorable (exergonic) rxn such as ATP cleavage/hydrolysis
(favorable cleavage allows unfavorable rxn to proceed)
, ◉ glutamate + NH3 + ATP --> glutamine + ADP +Pi
Answer: example of coupled rxn: making of glutamine
◉ enzyme
Answer: protein biological catalyst, shape determine activity, lower
Ea (do NOT make ender rxns exer)
◉ exergonic rxn
Answer:
◉ endergonic rxn
Answer:
◉ active site, induced fit
Answer: where the substrate binds to the enzyme, binding produces
____ to enzyme
◉ sucrose + H2O--(sucrase)--> glucose + fructose
Answer: example of catabolic rxn: hydrolysis of sucrose
◉ hexokinase enzyme for glucose
