12.Which statement(s) about control strategies is/are incorrect? Choose any that apply.

a) An advantage of a feedforward system is that it allows the body to anticipate a change, or prepare for something to happen.

b) A disadvantage of a feedforward system is it doesn’t allow you to respond to an unexpected change.

c) An advantage of a positive feedback system is allows for rapid changes to a regulated variable.

d) A disadvantage of a positive feedback system is that it is not homeostatic. e) A disadvantage of a negative feedback system is it requires some outside event to stop the response.

15. An 18-year-old girl presents with a lack of secondary sexual characteristics, such as age-appropriate pubic hair growth and breast development. Her history reveals she has never started menses. She is diagnosed with a deficiency. The levels of various steroid hormones in her serum are found to be abnormal.

20. Many people die each year from ingesting antifreeze solutions. Antifreeze contains ethylene glycol, which the human body converts to oxalic acid in the presence of the enzyme alcohol dehydrogenase. Oxalic acid exists in crystalline form and these crystals can severely damage kidneys. Ethanol is administered to victims with ethylene glycol poisoning because ethanol binds to the active site of alcohol dehydrogenase, inhibiting the formation of oxalate crystals. How would you classify ethanol in this scenario?

a) allometric inhibitor of ethylene glycol

b) allosteric inhibitor of ethylene glycol

c) cofactor of ethylene glycol

d) competitive inhibitor of ethylene glycol

e) covalent inhibitor of ethylene glycol
