BIO 105 Lecture Notes - Lecture 13: Contact Inhibition, Facilitated Diffusion, Nondisjunction
Document Summary
Do know what nondisjunction can result in the kinds of abnormalities. High to low is the same as going down the concentration gradient. Endo/exocytosis for large molecules own category of moving things in and out of cell results in changed shape of membrane. Water does not always travel using aqua something . When it needs to be done quickly it can be done. Normal human cells need to be anchored to divide cancer cells do not. They will divide and form a monolayer inhibited by contact. They will not just keep piling up- cancer cells will. They have lost contact inhibition and anchorage dependence. Hypotonic water solution that causes cell to swell very dilute solution. Hypertonic very salty/sugary solution has lots of solutes. Movement of water in and out of cell. The solution is either isotonic, hypotonic, or hypertonic this determines which way the water moves.
