FSU BCH 4053 exam 1 review
Four properties of living systems ANS:1) Living Organisms are complex and highly organized
2) Biological Molecules serve functional purposes
3) Living systems are actively engaged in energy transformations
4) Living systems have a remarkable capacity for self-replication
Trace elements ANS:Other elements that are present in limited systems and amounts
Elements in biomolecules ANS:The most common are C, N, O, and H. In smaller quantities are Ca, P, K, S,
Cl, Na, and Mg
Types of biomolecules studied in biochemistry ANS:Carbohydrates
Lipids
Proteins
Nucleic Acids
Major precursors of biomolecules ANS:H2O, CO2, NH4+, NO3-, and N2.
Structure of alkene ANS:
Structure of alcohol ANS:R-OH
Structure of amine ANS:
structure of aldehyde ANS:
, Structure of ketone ANS:
Structure of carboxylic acid ANS:
Structure of ester ANS:
Structure of peptide/amide ANS:
What do amino acid metabolites become? ANS:Proteins
What do nucleotide metabolites become? ANS:DNA and RNA
What do sugar metabolites become? ANS:Polysaccharides
What holds together supramolecular complexes, membranes, and macromolecules? ANS:These
structures are held together by intermolecular forces rather than covalent bonds. This makes them
more vulnerable to changes in the cellular environment. The most prevalent force being hydrophobic
interactions between the aqueous environment in and outside of the cell with the lipid in the
membrane.
Directional of biomolecules ANS:Most biomolecules have a head and a tail and unlike smaller molecules
are not symmetrical.
Information of biomolecules ANS:they are constructed like sentences with the monomer units (amino
acids, nucleotides, etc.) providing the alphabet.
Function of plasma membrane ANS:A selectively permeable phospholipid bilayer that encloses the cell.
