We’ve resolved most of the exam upload issues (yay!). We’re still missing uploads from a couple students but we’re working on that. In the meantime, I’ve uploaded everyone else’s score to Canvas.
There was one question that a lot of students got wrong – it’s this one:
Proteoglycans are composed of a ____ core with a bunch of attached ____.
A. Carbohydrate / proteins
B. Glycosaminoglycan / carbohydrates
C. Glycosaminoglycan / proteins
D. Protein / carbohydrates
E. Protein / glycosaminoglycans
The correct answer is E, and about half of the class answered correctly. Most of the rest of the class answered D, and a few answered A or C.
Here’s an explanation of what this question was trying to ask you about:
This question is based on the CT lecture objective that asks you to compare and contrast the structure of glycosaminoglycans, proteoglycans, and glycoproteins. There is a lecture slide that contains drawings and descriptions of both proteoglycans and glycoproteins – and the proteoglycan description states: Proteoglycans consist of a protein core with a bunch of attached glycosaminoglycans. So this question was testing to see if you knew the structure of proteoglycans.
I’ve added a point to everyone’s score to make up for the confusion. The total number of points for this exam will remain at 40, so this added point will be considered an extra credit point.
This is kind of a minor thing, since it’s just one point, but it does mean that when it comes time to calculate your final score, this extra point will carry a little more weight since it’s above and beyond the point total for the course.
Finally: I’ve released your scores to your Examplify portal, which means that you can see which questions you got wrong, and what the correct answers for those questions are. Please let me know if you are having trouble accessing your Examplify portal.
I think that’s it for now. As always, please let me know if you have any questions.
