Welcome to Cell facility before we start there are things need to know at the board.
Welcome to cell membrane!
Wow so cool!
This is the transport bus that moves the molecules and nutrients around the body and in and out of cells.
Structural proteinsstrengthen cells, tissues, organs, andmore. Nature can buildmaterials that are verystrong
I want to gain weights too soo cool. No pain no gain!
We're now inside of one of the channel proteins. Those bubble-like things you see floating around are molecules. The channel protein allows molecules to enter into the cell. This is an example of facilitated diffusion.
These are phospholipids. They participate in passive transport. In endocytosis, the phospholipids form a vesicle to allow molecules to enter, and vice-versa with exocytosis.
