Correct
Which pathway produces products used to make the subunits of DNA? -
ANSWER -Pentose phosphate pathway
The production of foods such as pickles and sauerkraut use the products of which
of the following? - ANSWER -Heterolactic fermenting bacteria
Which of the following can be synthesized by two different Krebs cycle
intermediates? - ANSWER -Nucelotides
At the end of aerobic cellular respiration, electrons are reduced to form which of
the following? - ANSWER -Water
Electron carriers belong in which group of organic molecules? - ANSWER -
Nucleic acids
Which of the following is the correct description of a coenzyme? - ANSWER -It is
an organic molecule that serves to help an apoenzyme fit with the substrate
Amino acids being used to synthesize large complex proteins are an example of
which of the following? - ANSWER -Anabolic, endergonic reactions
Which of the following is a distinction between the Krebs cycle in eukaryotes and
prokaryotes? - ANSWER -The process occurs in the mitochondria of eukaryotes
Which of the following is a correct comparison between fermentation and
anaerobic respiration? - ANSWER -Both can occur without oxygen present;
however, fermentation uses organic molecules has the final electron acceptor
,Describe the general makeup of organic molecules. - ANSWER -Organic
molecules are composed of carbon and small subunits that link together in an
organized manner
What are the four polymers: - ANSWER -Proteins
Lipids
Carbohydrates Nucleic acids
what is a Monomer - ANSWER -small subunits that make up polymers
Hydroxyl(O-H) - ANSWER -add to the polarity of the molecule, changes the
interactive properties of the molecule - not in fatty acids= no polarity
CH2O - ANSWER -a hydrated molecule because it has H2O also known as a
carbohydrate
COOH - ANSWER -carboxylic acid group
Saturated - ANSWER -the number of hydrogens along the carbon chain
Unsaturated - ANSWER -must have at least one double bond along the carbon
chain, which does not leave binding sites for as many hydrogen atoms; fatty acid
chain containing fewer hydrogens
Glycerol - ANSWER -a monomer of fat
Hydrophilic - ANSWER -another word for polar
Amino acid - ANSWER -monomer of protein
Potential energy: - ANSWER -needed for cellular activities
Functional groups - ANSWER -attach to carbon skeleton and change the
properties of the molecule
, Saccharide - ANSWER -refers to sugars or sweet molecule
Glyceride - ANSWER -refers to glycerol of a fat or fatty acid
mono
di
tri
poly - ANSWER -1
2
3
many
Oligopeptide - ANSWER -refers to shorter peptide chains
- ose: - ANSWER -a type of sugar or polysaccharide
Ester linkage: - ANSWER -a bond that forms between the hydroxyl groups of
glycerol and the carboxylic acid group of a fatty acid
Glycosidic bond: - ANSWER -a bond that forms between hydroxyl groups of
monosaccharides
Peptide bond: - ANSWER -a bond that forms between the amino group of one
amino acid and the carboxylic acid groups of the next amino acid
Sulfhydryl (S-H) - ANSWER -on disulfide bonds
Phosphate (PO3H2) - ANSWER -
Cell membrane contians - ANSWER -phospholipids, transport proteins, and
glycolipid
Cell wall contains - ANSWER -peptidoglycan, chitin, and cellulose
Storage contains: - ANSWER -starch, fat, and glycogen
