Reflection 6.2-6.3

In 6.2-6.3, I learned about the cell membrane and how important of a role it has in the processes of cells

  • Specifically, I focussed on what they are made up of. Membranes are made up of phospholipids, proteins, and carbohydrates. The membrane must be fluid so that things can move in and out of it easily. Therefore, the phospholipids, proteins and carbs must be held together loosely by weak interaction. 
  • What I found a little difficult was the importance of the phospholipid bilayer and its relationship with proteins.
  • How is structure related to function?
    • The weak interactions of the phospholipids and proteins allow the membrane to be fluid. A fluid membrane signifies that vesicles and other material can easily flow in and out of the cell through the cell membrane. 


  1. What exactly do you not understand between phospholipids and relationship with proteins? Try to articulate your confusion. This reflection is a good place to write and try to understand.

  2. I just didn't understand the connection between the two when I was reading. But I now understand that proteins can be embedded in the bilayer or they can be all the way inside or outside the cell. (transverse and integral). These proteins help transport the large molecules, the hydrophylic molecules, and ions.
