016 - Transport Across Cell Membranes
Paul Andersen describes how cells move materials across the cell membrane. All movement can be classified as passive or active. Passive transport, like diffusion, requires no energy as particles move along their gradient. Active transport requires additional energy as particles move against their gradient. Specific examples, like GLUT and the Na/K pump are included.

***** Most of the professors are researchers and they spend little efforts to teach students. Rather we get stuck with expensive poorly written textbooks and difficult tests that only a machine could pass.

***** Nope the problem is the tests are way to hard, some students pass through 2 methods, A: cheating (which hurts the curve that other students rely on to pass) and B Machine studying which alot of students (myself included) cannot do.

your lessons have saved me multiple times. I love studying biology but my teachers force me to memorize it without trying to understand it. They don't even make an effort to explain it, they just tell me to memorize it. It sucks because it has made me hate studying even though I used to love it. Coming back to your channel and revising this has been very helpful. Thank you a lot!

I decided to watch your videos so I could put down the book, and not only do I have a clearer understanding of many of the topics now, but your videos have really renewed my interest for biology. Thank you.

Mr. Andersen doesn't just talk about the topic but really knows what to point to in order to make us understand why we're being taught these things. A great example was the video on Environmental Matter Exchange. In my textbook, I can only remember learning about the cycles of nitrogen, carbon and water, and learning it from that angle is missing the point.

Hey +Camila Orejuela, osmosis is the pass of water across the cell membrane, diffusion is about other kinds of cells, as glucose,oxygen and carbon dioxide, Osmosis is the act of the water molecules moving to provide balance between inner cell and the outside, as the diffusion can be either random movements of molecules or molecules passing by, in this way that the cell helps in many processes, like transporting molecules through the tissues and stuff. Osmosis is the balance a kinda of pressure on the cell, that's why it's important to maintain the level of water in the body, otherwise there would be so many water that the cell would explode!

@vshubh123 Yes and no. Although water molecules are polar, they can diffuse across a cell membrane because they are so small. However, this process is relatively slow so many cells have developed aquaporins to help speed up osmosis.
