I know it's going to seem like I am fawning over the Deep Sea News blog (and I guess I am a bit), but this post was really too relevant to pass up...
Their newest "Thing to know about the deep sea" post basically discusses everything we covered in the first term of class - biochemistry, cell membranes, phospholipds, saturated and unsaturated fatty acids, transport across membranes, enzyme kinetcis, etc. - all with a deep sea twist. In fact, I bet you guys could figure out some of the details given what you learned back at the beginning of the semester.
In fact, before you click over to their post, think about the following details about the deep sea and how it might affect the biochemistry of cell membranes and enzymes (this is a good way to review the past material too!):
a) In the deep sea pressure on cell membranes may be as much as 1,000x more than on land.
b) The deep sea is very cold (as low as -1 degree C)
How do you think these two things would affect:
1) The fluidity of cell membranes
2) The function of enzymes
And how do you think deep sea critters have handled these effects? Post your ideas here in the comment section before moving on to check out the post.
