Cell Transport Systems

We are going to be starting Chapter 4. It is about the cell membrane and how cells move materials in and out. Discuss some of the different transport systems including diffusion, osmosis, facilitated diffusion, active transport, endocytosis, exocytosis. Also, retakes will be available on the amino acid quiz on Tuesday, and there will be a Unit 1 Exam on Wednesday, so you should start preparing for that. If you would like, you may start a posting that asks questions, and use the blog as a tool to communicate with your classmates on topics that you are having problems with.

Do a little research!

What are the differences between high density and low density lipoproteins? Also, what are some of the other uses for lipids in the human body? How are carbohydrates used by the human body?

Biochemistry

Why is it so important to know about the chemistry of macromolecules when we are going to discuss cellular biology? Also, how are lipids different from carbohydrates in the way they are structurally designed?
