AP Biology Enzymes and Thermodynamics
UPDATED ACTUAL Exam Questions and
CORRECT Answers
metabolism - CORRECT ANSWER - all chemical processes that either break down or build
up large molecules
2 types of metabolism: - CORRECT ANSWER - catabolic and anabolic
catabolic - CORRECT ANSWER - break down, hydrolysis, digestion, mostly exergonic
reactions, results in higher disorder
anabolic - CORRECT ANSWER - building processes, dehydration synthesis, endergonic
processed, lower disorder
anabolism+catabolism - CORRECT ANSWER - =metabolism
ATP(adenosine triphosphate) and components - CORRECT ANSWER - modified nucleotide
3 phosphate, ribose, adenine
function of ATP - CORRECT ANSWER - provide energy for chemical reactions in cells
what happens when ADP gains Pi? - CORRECT ANSWER - reforms ATP
what does ATP provide?why? - CORRECT ANSWER - -small units of energy that can be
easily used to fuel single steps of chemical reactions
-this is because less is lost as heat and light
, energy - CORRECT ANSWER - ability to do work and create heat
potential energy - CORRECT ANSWER - stored form of energy
where is potential energy stored in living organisms? - CORRECT ANSWER - chemical
covalent bonds of large molecules
how do you you release the energy? - CORRECT ANSWER - break the bonds
kinetic energy - CORRECT ANSWER - energy in motion
how is kinetic energy used in living organisms? - CORRECT ANSWER - move the
organisms, its cells, or molecules
1st law of thermodynamics/law of conservation of matter and energy - CORRECT
ANSWER - energy can't be created or destroyed but can change forms;all living organisms
directly or indirectly use the energy from the sun
second law of thermodynamics - CORRECT ANSWER - every spontaneous process in the
universe heads to a larger disorder
measurement of disorder - CORRECT ANSWER - entropy
what is the most disorganized form of energy? - CORRECT ANSWER - usable forms of
energy are converted to unusable heat
exergonic reactions and ex. - CORRECT ANSWER - chemical reaction that releases energy as
heat, sound, and light
ex. burning wood
