As we examine the rate of enzyme function in vitro (that is, in the test tube or cuvette) remember that the conditions for this measurement may differ significantly from the enzyme's native environment in the cell. Identify two ways in which the cell's composition and internal environment may differ from our experimental conditions, and how these might impact the function of the enzyme (hint: think about the name of our enzyme)

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?
