List of important questions for A.P.
Biology
- Write the solution of CO2 and the dissociation of
carbonic acid.
- Describe the chemical test for starch, glucose, halides.
- Draw and label an amino acid.
- List 3 uses of radioisotopes in biology.
- Draw 3 structural isomers of pentose. Could pentose have a
stereoisomer?
- List the 4 levels of protein structure and the bonds involved
in each
- Describe the pH scale and the amount of difference between any
two pH's
- Know the difference between hydrolysis and dehydration (or
condensation) reactions and be able to predict the amount of water
produced in peptide, glycosidic and ester linkages.
- Describe the meaning of each term in the equation for the
Second Law of Thermodynamics.
- List six characteristics of enzymes.
- Discuss how enzyme activity can be measured in general, and
how this activity was measured in the amylase lab
specifically
- Describe how some proteins need to be spatially arranged in a
particular way in cell membranes and how they contribute to
membrane function. List at least four types of protein found in
the plasma membrane.
- Describe the arrangement of phospholipids in membrane
structure and how the hydrophobic interactions of the fatty acid
tails help determine membrane function
- Explain why it is that molecules such as water, oxygen, carbon
dioxide, and steroid hormones pass easily through the plasma
membrane while glucose and many essential ions have difficulty in
doing so.
- Explain what mechanisms can generate a membrane potential or
electrochemical gradient
- Discuss why bacteria and other microorganisms fail to grow on
food that has been preserved by the addition of large amounts of
salt or sugar.
- Describe a simple signal-transduction pathway across a
membrane including the role of first and second messengers.
To be continued.
