  1. What two functional groups combine to form an amino acid?
    an amino group and a carboxyl group
  2. Monosaccharides are multiples of what molecule?
    CH2O
  3. In what organisms would you find cellulose?
    plants
  4. How does cellulose contribute to the human diet?
    in the form of insoluble fiber
  5. Which type of fat will have double bonds in it's fatty acid tail, saturated or unsaturated?
    unsaturated
  6. Do saturated fats have straight, or bent tails?
    straight tails
  7. This type of fat has bent fatty acid tails.
    unsaturated fatty acids
  8. Will saturated fats be liquid, or solid at room temperature?
    solid
  9. Will unsatured fats be liquid, or solid at room temperature?
    liquid
  10. What are the four primary functions of the cell membrane, as discussed in lecture?
    • physical isolation of environments
    • regulation of exchange
    • sensitivity to environment
    • structural support
  11. What is diffusion?
    the movement of solutes from an area of higher concentration to an area of lower concentration
  12. Moving a liquid across a porous membrane leaving behind larger particles is known as:
    filtration
  13. What is osmosis?
    the diffusion of water across a selectively permeable membrane
  14. The main tenet of osmosis is that water will follow:
    solutes
  15. How does osmotic pressure affect osmosis?
    the higher the pressure, the less osmosis can occur
  16. What is a hypertonic solution?
    a solution with a higher concentration of solutes
  17. What is a hypotonic solution?
    a solution with a lower concentration of solutes
  18. A solution with an equal concentration of solutes is said to be a _________ solution.
    isotonic
  19. What will happen to a red blood cell in an isotonic solution.
    nothing, it will exhibit no net movement of water
  20. What will happen to a red blood cell in a hypotonic solution?
    water will move into the cell, causing cell lysis
  21. A red blood cell that is undergoing crenation is most likely in what type of solution?
    hypertonic
  22. What does a symport do?
    it moves two solutes across the cell membrane in the same direction
  23. A channel in the cell membrane that moves two solutes in opposite directions is called a/an:
    antiport
  24. The process that brings "stuff" inside a cell is known as:
    endocytosis
  25. The process that takes "stuff" out of the cell is known as:
    exocytosis
  26. Pinocytosis can be thought of as:
    cell drinking
  27. Phagocytosis is the process of:
    cell eating
  28. What is/are the functions of ribosomes?
    they are the location of protein synthesis
  29. List the structures that comprise the endomembrane system.
    • nuclear envelope
    • endoplasmic reticulum
    • golgi apparatus
  30. What are the three major functions of the smooth endoplasmic reticulum discussed in lecture?
    • fat or lipid synthesis
    • metabolize carbohydrates
    • detoxification processes
  31. What are the two major function of the rough endoplasmic reticulum that were discussed in lecture?
    • protein synthesis
    • make components of the cellular membrane
  32. Which side of the Golgi apparatus faces the endoplasmic reticulum?
    the cis side
  33. The side of the Golgi apparatus that faces the plasma membrane is known as the:
    trans side
  34. What is the function of the Golgi apparatus?
    it is the processing, packaging, and distribution center of the cell
  35. What type of vesicle leaves the ER headed for the Golgi?
    a transport vesicle
  36. The Golgi dispatches materials bound for the plasma membrane in what type of vesicle?
    a secretory vesicle
  37. What is the function of mitochondria?
    site of ATP synthesis
  38. What is the equation that represents cellular respiration?
    C6H12O6 + 6O2 = 6CO2 + 6H2O + ATP
  39. Does oxidation involve the gain or loss of electrons?
    the gain of electrons
  40. Reduction results in a _____ of electrons.
