A cell membrane is damaged by inseion of a micro needle, repair shall occur by which of the following process?
Lateral movement of proteins
Enzyme catalysed process
Hydrophobic interactions
An active process involving hydrolysis of ATP
Ans. a. Lateral movement of proteins (Ref Harper 29/e p464, Ganong 24/e p36)Harper says 'Another indicator of the dynamic nature of membranes is that a variety of studies have shown that lipids and ceain proteins exhibit lateral diffusion in the plane of their membranes
