  • 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.

      ***** The professors at my school were English speaking, however the actual teaching was done by TAs, one of the worst experiences in college I have had.

    • @lordmasterization
      @lordmasterization 8 років тому +10

      ***** 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.

    • @lordmasterization
      @lordmasterization 8 років тому +2

      ***** I am in the US, and mu community college courses were much more manageable than the ones at the University. They like to call them "drop out" courses but they are just bad programs staffed by bad professors.

    • @lordmasterization
      @lordmasterization 8 років тому +5

      ***** 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!

    hey, i really, really appreciate you taking the time and effort to make these videos... Earlier today I was getting SO frustrating trying to study and memorize everything for the ap exam tomorrow, that I even thought about just giving up and just accepting whatever score I would get! 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.

  • @orbsandtea
    @orbsandtea 11 років тому

    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.
