Big Idea 2 Biological molecules utilize free
energy molecular building blocks to grow, to
reproduce, and to maintain homeostasis

1. How do heterotrophs capture free energy present
   in carbon compounds produced by other organisms?
   Pg 25
2. Living systems depend on properties of water that
   result from its polarity and hydrogen bonding.
   Provide some examples that support this claim. Pg
   28-29

Big Idea 2 Biological molecules utilize free
energy molecular building blocks to grow, to
reproduce, and to maintain homeostasis

• Organisms must exchange matter with the
  environment to grow, reproduce and maintain
  organization.       3. Molecules and atoms from
  the environment are necessary to build new
  molecules. -Support the above statements
  with your understanding of the biogeochemical
  cycling and properties of water. Pg 28

Big Idea 2 Biological molecules utilize free
energy molecular building blocks to grow, to
reproduce, and to maintain homeostasis

• 4. Cell membranes are selectively permeable due
  to their structure.
• a. cell membranes separate the internal
  environment of the cell from external environment
• b. Selective permeability is a direct
  consequence of membrane structure, as described
  by the fluid mosaic model.
• c. Provide examples to support claims a b
  pg 31

Big Idea 2 Biological molecules utilize free
energy molecular building blocks to grow, to
reproduce, and to maintain homeostasis

• 5. Growth and dynamic homeostasis are maintained
  by the constant movement of molecules across
  membranes. Passive transport does not require the
  input of metabolic energy the net movement of
  molecules is from high concentration to low
  concentration. Support this claim with your
  knowledge of passive transport. Pg 32

6
Big Idea 2 Biological molecules utilize free
energy molecular building blocks to grow, to
reproduce, and to maintain homeostasis

• 6. Active transport requires free energy to move
  molecules from regions of low concentration to
  regions of high concentration. Support this claim
  with your knowledge of active transport.

7
Big Idea 2 Biological molecules utilize free
energy molecular building blocks to grow, to
reproduce, and to maintain homeostasis

• 7. The processes of endocytosis and exocytosis
  move large molecules from the external
  environment to the internal environment and vice
  versa, respectively.  Support this claim with
  your knowledge of cell transport.

8
Big Idea 4 Biological systems interact, and
these systems and their interactions possess
complex properties

• 8. The subcomponents of biological molecules and
  their sequence determine the properties of that
  molecule. Structure and function of polymers are
  derived from the way their monomers are
  assembled. Support the statement with evidence.
  Pg 81
• 9. Directionality influences structure and
  function of the polymer. Support this claim with
  evidence

Big Idea 4 Biological systems interact, and
these systems and their interactions possess
complex properties

• 10. The structure and function of subcellular
  components, and their interactions, provide
  essential cellular processes. (Ribosomes, ER,
  Golgi Apparatus/Complex, Mitochondria, Lysosomes,
  Vacuole, and Chloroplast) pg 82
