Chapter 4 Blog: General Features of Cells (Christina)

Page history last edited by Christina Datuin 13 years, 2 months ago

In the first section of this page, you will write a daily summary of that day's class.  For example in  your chapter 2 blog, your first entry should be titled 9/3/10.  You should then write a one or two paragraph summary of that day's lecture, outlining the major points.  In the second section, you are required to add two items (link to a website, video, animation, student-created slide show, student-created PowerPoint presentation) and one journal article pertaining to a topic in this chapter.  A one-paragraph summary must accompany each item describing the main idea and how it applies to the lecture topic.  Please see the PBWorks help guide for assistance embedding video and other items directly in the page.  I will also produce a how-to video on using tables to wrap text around items and other useful tips.  Please see the syllabus for organization and grading details.


A.  Daily Blog


9/22/10: Today, I learned about prokaryotic and eukaryotic cells. I knew a lot of the basic information about the cells prior to the lecture, but we went more into depth about it. We went into depth about the endomembrane system so I learned a lot about it. When I took Biology before, I didn't fully understand the "cargo" concept with the endoplasmic reticulum. But after today's lecture, I understood it completely. I didn't know that parts of it broke off before. This lecture just helped me understand how the cell works a lot better. It helped a lot. I also learned that sulfur is good to use to identify proteins.


9/24/10: Today I learned about phospholipids in plasma membranes.  In the past, my teachers have only gone into depth about the plasma membrane of the whole cell.  But during today's lecture, we went into detail on the Endoplasmic Reticulum plasma membrane.  It is generally the same as the cell plasma membrane, but there are slight differences.  I didn't know that the Endoplasmic Reticulum's plasma membrane looked the same as the cell plasma membrane. I learned more about how it works.  I also learned about which groups are polar and nonpolar. Then I learned about amino acid sequences.  We went into depth on translation and which amino acid sequences are important in it.


9/29/10: Today I learned about protein trafficking. We focused on that for the beginning of class. We talked about what it goes through, like transcription and translation. We also talked about the ER signal sequence. It is represented by a series of amino acids at the N-terminus targeted by SRP. We also did some examples of amino acid. In one of the examples, we identified what types of amino acids are most prevalent in the N-terminus of the endoplasmic reticulum signal sequence. then we learned about the binding cleft. We discussed the importance of the first 40 amino acid sequences are. If they are not present, protein can be translated but will not travel to the endoplasmic reticulum.

This video shows how protein trafficking occurs. It helped me a lot because I like to see how things happen. I am a visual learner at times, so I need to see what I am learning about. This did a great job at doing that.



This picture helped me understand how the "cargo" works in the endoplasmic reticulum. The visual helped me understand this concept as well.



This article is about protein trafficking.

Need more detail in your summary of your journal article.
