Chemical reactions carried out by living systems depend on the ability of some organisms to
capture and use atoms from nonliving sources in the environment. The specific subset of these
reactions that break down nutrients in food can be described as _________________.
(a) metabolic
(b) catabolic
(c) anabolic
(d) biosynthetic - answer✔✔(b) catabolic
When there is an excess of nutrients available in the human body, insulin is released to stimulate
the synthesis of glycogen from glucose. This is a specific example of a(n) _______________
process, a general process in which larger molecules are made from smaller molecules.
(a) metabolic
(b) catabolic
(c) anabolic
(d) biosynthetic - answer✔✔(c) anabolic
The second law of thermodynamics states that the disorder in any systems is always increasing.
In simple terms, you can think about dropping NaCl crystals into a glass of water. The solvation
and diffusion of ions is favored because there is an increase in ________________.
(a) pH
(b) entropy
(c) ions
(d) stored energy - answer✔✔(b) entropy

True or false: The second law of thermodynamics states that the total amount of energy in the
universe does not change. - answer✔✔False. The second law states that compounds of any
system move toward greater disorder
True or false: The ultimate source of energy for living systems is chlorophyll. - answer✔✔False.
The ultimate source of energy is sunlight.

answer✔✔False. The fixation of carbon from CO2 occurs independently of light.
True or false: H2 is the most stable form and abundant form of hydrogen in the environment. -
answer✔✔False. The most stable form of hydrogen is H2O.
In the first stage of photosynthesis, light energy is converted into what other form of energy?
(a) electrical
(b) chemical
(c) potential
(d) kinetic - answer✔✔(a) electrical or (d) kinetic
Light+________+__________ yields __________+ heat+sugars - answer✔✔H2O+CO2, O2
During respiration, energy is retrieved from the high-energy bonds found in certain organic
molecules. Which of the following, in addition to energy, are the ultimate products of
respiration?
(a) CO2, H2O
(b) CH3, H2O
(c) CH2OH, O2
(d) CO2, O2 - answer✔✔(a) CO2, H2O
Your body extracts energy from the food you ingest by catalyzing reactions that essentially
"burn" the food molecules in a stepwise fashion. What is another way to describe this process?
(a) reduction
(b) oxidation
