Biology Proteins in Plasma Membrane

AI Thread Summary
Proteins in the plasma membrane can cluster through interactions with the cytoskeleton, specifically actin microfilaments and intermediate filaments. Additionally, membrane proteins can bond with each other, forming clusters via interactions such as disulfide bridges and hydrogen bonds. Another important concept in protein clustering is the formation of lipid rafts or lipid microdomains, which are somewhat controversial but relevant in this context. These mechanisms highlight the complexity of protein organization within the plasma membrane. Understanding these clustering methods is essential for grasping cellular function and membrane dynamics.

Homework Statement



Describe the methods by which proteins are clustered in the plasma membrane.

Homework Equations


There are none really; it's theory.


The Attempt at a Solution


I understand that the proteins bond with the cytoskeleton (actin microfillaments and intermediate fillaments), but I can't seem to think of the second method. I do know that it is not that the proteins in the plasma membrane bond with the extracellular matrix. Perhaps it has something to do with the proteins bonding together? Such as polypeptides forming disulfide bridges, hydrogen bonds, or the like? Any insight would be greatly appreciated.

Yes, interactions between membrane proteins is another way in which you can cluster proteins at the plasma membrane. Another topic to look into (although somewhat controversial in the field) is the concept of lipid rafts or lipid microdomains.
 
Thread 'Confusion regarding a chemical kinetics problem'
TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
