  1.  Define Homeostasis:
  2. Identify the five components of a feedback loop. List them in the form of a flow chart.
  3. Define Negative feedback loop:
  4. Define Positive feedback loop:

Case #1:

  • What is the stimulus of this control loop?______________
  • What is the control center? _________________________
  • What is the effector? _____________________________
  • Oxytocin is playing the role of (receptor / afferent pathway /efferent pathway) in this control mechanism. (Circle one of the terms in bold.)
  • This is an example of ___ (positive/negative) feedback. How can you tell?

Case #2:

  1. What is the variable monitored by this loop?___________

  3. What is the control center? _________________________
  4. What is the effector? ______________________________
  5. What is the efferent pathway?_______________________
  6. This is an example of ___ (positive / negative) feedback. How could you tell?

  1. What is the stimulus of this control loop?______________
  2.  What is the control center? ________________________
  3. What is the effector? ______________________________
  4. In this feedback mechanism, insulin is acting as the (receptor / afferent pathway / efferent pathway). (Circle one of the terms in bold.)
  5. This is an example of ___ (positive / negative) feedback. How could you tell?

  •  Define the following
  • Metablism                                                          f) Catabolism
  • Anabolism                                          g) Enzymes
  • Macromolecules/Polymers              h) Monomers/Building Blocks
  • Chemical reactions to build and break polymers

i)Dehydration synthesis (DS)- reaction that break down polymers from monomers

ii)Hydrolysis (H)- reaction that breaks down polymers into monomers

  • Know macromolecules/polymers (and their respective monomers)

i)Classify each of the macromolecule into their different subclasses

ii) For each subclass that you listed above provide representative examples.
