what is the best representation of the central dogma of molecular biology? correct answers
the sequence of bases in DNA is used to code for a corresponding sequence of bases in RNA
(transcription) which codes for a particular sequence of amino acids in proteins (translation)
peptide bonds.. correct answers more than one of the following are true
alpha helix and beta pleated sheets are examples of: correct answers secondary structures
what type of bonds holds the 2 sides of the double helix of DNA together? correct answers
hydrogen
which of the following is NOT a part of a nucleotide? correct answers Genes
consider the 4 bases commonly found in the double helix of dna. which of the following
represents a correct representation of complimentary base pairing? correct answers 5' CGA 3'
to 3' GCT 5'
which of the following nitrogenous bases is found in RNA but not DNA? correct answers
Uracil
which of the following best explains why carbs are advertised by manufacturers of candy
bard and sports drinks as a quick energy boost? correct answers carbs have high energy
electrons that can ultimately be used to make ATP
what are the major functions of carbs in cells correct answers energy storage, cell id, structure
which aspect of phospholipids is most important to the formation of bilayers? correct answers
they consist of hydrophobic and hydrophilic regions
, what represents what happened when the black dots (solutes) were pumped out of the cell?
correct answers solutes were pumped out of the cell by active transport
which of the following is not true of osmosis? correct answers It is an energy-demanding or
"active" process.
Enzymes that readily break starch apart cannot break down the glucose molecules found in
cellulose. Why is this logical? correct answers the shape of the molecules is different and
enzyme active sites are highly specific
which of the following is true of exergonic reactions? correct answers they are energy
releasing and occur spontaneously when provided with a certain amount of initial energy
This region, also referred to as the mitochondrial matrix, is where the Krebs cycle takes
place. this cycle is the formation of NADH and FADH2 correct answers the matrix (D)
this region contains the ETC. the ETC is used to produce lots of ATP during aerobic cellular
respiration? correct answers inner membrane (B)
this region is where glycolysis occurs. correct answers cytosol (C)
this region is where glucose is converted to pyruvate and ATP can be produced whether or
not oxygen is present. correct answers cytosol (C)
why do yeast produce alcohol (ethanol)? correct answers More than the above- to regenerate
NAD+ from NADH so glycolysis can continue to produce ATP as long as glucose is
provided. and because yeast use ethanol as a source of energy.
