BIO 1201 EXAM 2 LICATA FINAL PAPER 2026
COMPLETE QUESTIONS AND CORRECT
ANSWERS
◉ free energy.
Answer: energy available to do work, negative is favorable
◉ energy coupling.
Answer: The use of an exergonic process to drive an endergonic one.
◉ ATP structure.
Answer: adenine, ribose, 3 phosphate groups (RAP)
◉ ATP hydolysis.
Answer: help makes unfavorable reactions become favorable, good
for endergonic reactions
◉ ATP.
Answer: renewable resource that is regenerated by addition of a
phosphate group to adenosine diphosphate (ADP)
,◉ enzymes.
Answer: proteins that act as biological catalysts, lower Ea and speed
up
◉ The active site can lower an EA barrier by.
Answer: 1. Orienting substrates correctly
2. Straining substrate bonds
3. Providing a favorable microenvironment
4. Covalently bonding to the substrate
◉ enzyme evolution.
Answer: Enzymes evolve to function in specific conditions
◉ cofactors and coenzymes.
Answer: cofactors are inorganic enzyme helpers, an organic cofactor
is a coenzyme
◉ competitive vs noncompetitive inhibitors.
Answer: Competitive inhibitors - reduce productivity of enzyme by
sticking mimic substrates into active sites, blocking substrates from
entering.
, Noncompetitive inhibitors - impede by interacting with enzyme at
other location (not at active site). Interaction causes enzyme to
change its shape that interrupts regular functioning
◉ allosteric regulation.
Answer: allosteric doesn't bind to active sites, it locks enzymes in
inactive or are active form
◉ special form of allosteric regulation.
Answer: cooperativity, one active site affects a different active site
◉ localization of enzymes.
Answer: another method of controling metabolic pathways
◉ aerobic respiration.
Answer: consumes organic molecules and O2 and yields ATP
◉ fermentation.
Answer: A catabolic process that makes a limited amount of ATP
from glucose without an electron transport chain and that produces
a characteristic end product, such as ethyl alcohol or lactic acid.
◉ oxidation.
