BIO 1201 GREGG EXAM 2 STUDY GUIDE
2026 VERIFIED QUESTION SET AND
SOLUTIONS
◉ Metabolism.
Answer: All of the chemical reactions that occur within an organism
◉ active transport.
Answer: cytoplasm of cell has a higher concentration of k+ ions. How
will K+ ions enter the cell?
◉ metabolic pathway.
Answer: Begins with a specific molecule, which is then altered in a
series of defined steps, resulting in a certain product.
◉ Energy.
Answer: the capacity to cause change
◉ Law of Conservation of Energy.
Answer: the law that states that energy cannot be created or
destroyed but can be changed from one form to another
,◉ second law of thermodynamics.
Answer: Every energy transfer or transformation increases the
entropy of the universe.
◉ free energy.
Answer: the portion of a system's energy that can perform work
when temperature and pressure are uniform throughout the system
◉ spontanous.
Answer: releases free energy (exergonic) (negative delta G)
◉ nonspontaneous.
Answer: requires free energy (endergonic)
◉ Delta G= Delta H- T Delta S.
Answer: H=enthalpy- total energy
G=free energy
T=temperature
S=entropy or unusable energy
◉ ATP.
, Answer: main energy source that cells use for most of their work
(ribosomes, adenine and 3 phosphate groups)
◉ energy coupling.
Answer: The use of an exergonic process to drive an endergonic one.
◉ ATP powers cellular work by.
Answer: coupling exergonic reactions to endergonic reactions
◉ catalyst.
Answer: chemical agent that speeds up the rate of a chemical
reaction
◉ activation energy.
Answer: speeds up reactions and weakens bonds so that they are
able to break and reform
◉ orienting substrates correctly,
straining substrate bonds,
providing a favorable microenvironment,
covalently bonding to the substrate.
Answer: active site of an enzyme can lower the Ea barrier by
