Homeostasis correct answersRegulation of the body's internal environment; must respond to environmental challenges. Law of Mass Balance correct answersLaw that states that the amount of substance in the body is to remain constant, any gain must be offset by an equal loss. Negative feedback loop correct answersSomething is wrong in a body system that is sensed and there is a response that is generated which returns the system to a homeostatic state (stabilizes variable). Positive feedba...

what are membrane functions? correct answers 1) separate cells from the external medium to create an intracellular environment of unique and defined composition 2) allow selective transport of substrates in and out of the cell 3) provide a location for specialized pathways and processes (energy conversion of mitochondria) 4) rapid changes in electric potential across the membranes of neurons as basis of the nervous system 5) localization of receptors to facilitate response to physiological s...

CHEM 210 Module 5 Exam Newest 1. How is the definition of lipid different from protein and carbohydrate?: The lipid definition is based on the functional definition of being soluble in a non-polar solvent. Proteins and carbohydrates are based on the structure. 2. What are three functions of lipids?: Any three of: energy, storage, vitamin, protection, and insulation 3. How does the omega numbering system differ from the simplified nota- tion?: The ...
