Document Summary

*this is not the best study guide, i made it before i really had the rhythm of the class* Things to know for physio: define homeostasis and describe the elements that comprise a feedback loop. Identify a representative example of a positive vs. a negative feedback loop, and explain why one category is called positive" and the other is called negative. ": positive feedback loop- a mechanism in which a stimulus is amplified a. i. Negative feedback loop- the process in which a stimulus is detected and reversed b. i. Example- when you are hot you sweat to cool down: compare and contrast the structural elements of integral and peripheral membrane proteins that influence their interaction with membranes; include the concepts of lipophilicity" vs. Hydrophilicity" or, alternatively, non-polar vs. polar. " explain why the amphipathic structure of phospholipids and integral membrane proteins is important in establishing stable membrane structure: polar a. i.
