AP BIOLOGY ENZYMES AND
THERMODYNAMICS EXAM
QUESTIONS WITH COMPLETE
ANSWERS
cofactors and ex. - ANSWER-inorganic molecules, like metal ions Fe+2, Zn+2, Mg+2
coenzymes - ANSWER-molecules such as vitamins
feedback inhibtion - ANSWER-multi-step metabolic processes are regulated in this
way
what happens in these processes? - ANSWER-the last product becomes an
allosteric inhibitor of the first enzyme. If the 1st enzyme doesn't work, the entire
process shuts down
metabolism - ANSWER-all chemical processes that either break down or build up
large molecules
2 types of metabolism: - ANSWER-catabolic and anabolic
catabolic - ANSWER-break down, hydrolysis, digestion, mostly exergonic reactions,
results in higher disorder
anabolic - ANSWER-building processes, dehydration synthesis, endergonic
processed, lower disorder
anabolism+catabolism - ANSWER-=metabolism
ATP(adenosine triphosphate) and components - ANSWER-modified nucleotide
3 phosphate, ribose, adenine
function of ATP - ANSWER-provide energy for chemical reactions in cells
what happens when ADP gains Pi? - ANSWER-reforms ATP
what does ATP provide?why? - 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 - ANSWER-ability to do work and create heat
potential energy - ANSWER-stored form of energy
where is potential energy stored in living organisms? - ANSWER-chemical covalent
bonds of large molecules
