Serine is an example of a(n) ...., maltose is an example of a(n) examples of ..., guanine is an
example of a(n)... and stearate is an example of a(n)... correct answers amino acid; simple sugar;
nucleotide; fatty acid

why can humans digest starch but not cellulose or chitin? correct answers humans lack the
necessary enzymes

in the following set of reactions, which reactant is the shared intermediate?
A + B --> C + D
C + E --> F correct answers C

which molecular event is most responsible for transducing the signal from outside of the cell to
inside of the cell? correct answers informational change in the receptor

The ... strand is the same sequence as the mRNA, whereas the ... strand is complementary to the
mRNA sequence is 5'-...3', which encodes the amino acid .... correct answers coding; template;
UCC; serine

in aerobic respiration, the reductant (reducing agent) is ... and the oxidant (oxidizing agent) is ...
with carbon dioxide being one of the products and .. being the other product. The conversion
of ... energy to chemical energy generates ATP for use in metabolism correct answers glucose;
oxygen; water; redox

what happens to an organism if it is no longer able to convert energy from the environment
(nutrients or sunlight) into chemical energy? correct answers it reaches equilibrium with the
environment and dies

accurately described the difference between the actual change in free energy and the standard
change in free energy correct answers the standard change in free energy reflects the potential
energy in reactants and products independent of concentration whereas the actual change in free
energy is dependent on the concentration of reactants and products under steady state conditions.
the actual change in free energy changes in response to the environments whereas the standard
change in free energy is a constant for a given reaction

anabolic pathways are most active when the energy charges is ... whereas catabolic pathways are
most active when the energy charge is .... The source of energy for .. .pathways is stored fuels
whereas the source of energy for .. pathways is abundant resources from the environments
(nutrients or sunlight) correct answers high; low; catabolic; anabolic

the evolution of antifreeze proteins is an example of two proteins that are correct answers
different structure, similar function

, why is it energetically favorable to form one large oil droplet (protein complex) rather than many
oil droplets (proteinmonomers) in an aqueous solution? correct answers because tere is less
ordered water with large oil droplets, so higher entropy overall

choose two correct statements below regarding the effect of NaCl in colution on the integrity of
the red blood cell membrane correct answers when placd in a hypertonic solution, the RBC will
shrink because H2O inside the cell is higher than the H2O outside te cells
when placed in a hypotonic solution, the RBC will burst because H2O outside the cell sis higher
than the H2O inside the cell

a solution with a [H+] of 1 x 10-9 M has a pH of ... and a [OH-] concentration of 1 x 10- ... This
is considered a(n) ... solution, whereas a solution with a pH of 4 would be considered a(n) ...
solution correct answers 9; 5; basic; acidic

the membrane separating the outside of the cell from the inside of the cell is called the ...
membrane. The membrane separating th eDNA in the nucleus from the cytoplasm is considered
part of the ... system. The ... membrane is found only in plant cells and represents an organelle
membrane correct answers plasma; endomembrane; chloroplast

the cell fusion experiment using heterokaryons provided evidence that correct answers
membrane proteins are able to move laterally across the cell surface

adenine is a ... whereas adenosine is a ... uracil is only found in ,, whereas ... is only found in
DNA. The difference between a nucleoside and a nucleotide and the presence of one or more ...
atoms correct answers base; nucleoside; RNA; thymine; phosphate

select the two pieces of evidence indicating that base stacking contributes more to DNA helix
stability than does base pairing through hydrogen bonds correct answers even though the number
of ydrogen bond formed between bases in the double helix is the same as the number of
hydrogen bonds formed between bases and water, the double helix is favored
base stacking energies are distinctly different between G:C/C:G and C:G/C:G

what contributes to DNA double helix stability. Choose all that apply correct answers NaCl
high G-C content
low temperature

which enzyme makes double strand breaks in DNA (a) and which enzyme makes single strand
breaks in DNA (b)? correct answers (a) topoisomerase II (b) topoisomerase I

why is uracil only in RNA and thymine only in DNA correct answers uracil can be formed by
cytosine deamination so if uracil were normally in DNA then both spontaneous sytosine
deamination and naturally-occuring uracil would be indistinguishable and G-C to A-T mutations
would build up quickly

why is eukaryotic DNA, such as human DNA, packaged into nucleosomes with histone proteins
but prokarotic DNA, such as bacterial DNA, is packaged into nucleosomes: correct answers
