BIO 3153 Lecture Notes - Lecture 15: Electrochemical Gradient, Calcium Atpase, Atp Hydrolysis
Document Summary
Depending on what proteins are expressed, it will have selective permeability. Basically this is the number of mechanisms that maintain a cell in it"s normal state, whether that"s maintaining ph, calcium and potassium levels, co2 and. When these are lost, cell starts to lose it"s equilibrium. There are a lot of factors to maintaining cells in their normal state. Multi-pass membrane proteins were inserted into the membrane back in the. Er, and sorted by the constitutive secretory pathway. These subunits of multi-pass proteins form these complexes (?) Inside of the membrane bilayer is very hydrophobic, and we"ve learned how proteins stabilize within the hydrophobic region (alpha-helices) Hydrophilic pore is conducive to the transport of hydrophilic molecules. O2 for example, diffuses quite readily, it moves quickly across the membrane. Water is another such molecule, and there are others, which can get across the membrane quickly.
