IB Biology- Molecular Biology Exam
Study Test.

Molecular biology - CORRECT ANSWER living processes in terms of chemicals involved



Carbon - CORRECT ANSWER forms many different compounds due to four available covalent bonds



metabolism - CORRECT ANSWER series of enzyme controlled reactions



anabolism - CORRECT ANSWER synthesis of macromolecules from monomers via condensation which
produces water



catabolism - CORRECT ANSWER breaks down larger molecules into smaller monomers via hydrolysis-
this uses water



vitalism - CORRECT ANSWER the products and components of living organisms, such as urea, can only be
made by such.



Urea - CORRECT ANSWER through artificial synthesis of urea from inorganic chemicals, vitalism was
disproved



glucose - CORRECT ANSWER a monomer in a 6 carbon hexagonal shape



ribose - CORRECT ANSWER a monomer with a pentagonal shape- 4 carbon and a single oxygen



saturated fatty acid - CORRECT ANSWER long carbon chain with many hydrogen off shoots. At one end
double bond with O and OH groups

, generalised amino acid - CORRECT ANSWER N bonded with two H, C bonded with R side chain and H, C
bonded to OH group and double bond with O



hydrogen bonds - CORRECT ANSWER form between water molecules (O attracted to H due to polarity)



cohesive - CORRECT ANSWER water molecules stick to eachother



adhesion - CORRECT ANSWER water molecules stick to other substances



solvent - CORRECT ANSWER water can dissolve similarly polar substances and ions



specific heat capacity - CORRECT ANSWER amount of energy released or absorbed as water changes
state- for water this is high



boiling point - CORRECT ANSWER high for water at 100 due to strong hydrogen bonds



freezing point - CORRECT ANSWER water becomes less dense as gets closer to freezing point



hydrophobic - CORRECT ANSWER aversion to water



hydrophilic - CORRECT ANSWER attracted to water



methane - CORRECT ANSWER non-polar with weak forces with no H bonds, thus lower heat capacity,
lower melting and boiling points



coolant - CORRECT ANSWER water acts as a coolant when expelled from body. absorbs much more heat
energy to evaporate due to high specific heat capacity



solubility in water - CORRECT ANSWER Polar glucose is soluble in water. Amino acids generally are with
the ions of amino acid playing a part. Cholestrol has a non-polar tail and thus is insoluble. Fats too are
non-polar. Oxygen has limited solubility, thus the need for hemoglobin.
