◉ The shared biochemistry of all life is often considered evidence
for: Answer: Shared common descent of all life on earth.
◉ Water has which property or properties? Answer: Hydrophilic
Forms hydrogen bonds
◉ Ocean acidification is resulting due to Answer: Global release of
CO2 through the use of fossil fuels
◉ Which other element (besides Carbon) is often suggested as
having potential for life Answer: Silicon
◉ Which kind of organic compound is pictured? Answer: Amino acid
◉ What kind of molecule is pictured? Answer: RNA
◉ Which kind of organic compound is pictured? Answer:
phospholipid
,◉ All things being equal which fatty acid will have a lower melting
point? Answer: Short-chain fatty acid
◉ What kind of molecule is pictured? Answer: polypeptide
◉ Saturated or unsaturated fat? Answer: saturated(top)
◉ Which type of molecular interaction is strongest? Answer:
Covalent bond
◉ Water is a... Answer: polar molecule
◉ A low pH is typical of Answer: acids
◉ What element is called the 'backbone of life'? Answer: carbon
◉ DNA or RNA? Answer: DNA
◉ This amino acid is capable of forming disulfide bridges Answer:
Cysteine
◉ Name this compound... Answer: Cholesterol
, ◉ Exothermic or Endothermic? Answer: exothermic
◉ Which level of protein structure? Answer: Quaternary
◉ The name of a conceptual model for enzyme action Answer: Lock
and Key, Induced Fit
◉ Which level of protein structure is shown in the picture below?
Answer: Primary
◉ Which level of protein structure is shown in the picture below for
the two proteins? Answer: tertiary
◉ Would the subsitution (due to a mutation) of alanine
(hydrophobic amino acid) for serine (a polar and hydrophobic
amino acid) have a large or small effect on the structure of a protein?
Answer: Yes, likely a large effect. The substitution of two chemically
very different amino acids could have a large effect on protein
structure.
◉ What type of chemical bond is important for stabilizing alpha-
helix or Beta-sheets between backbone atoms of amino acids in
close proximity to one another? Answer: Hydrogen bonds
