Singer And Nikolson Fluid Mosic Model

Fluid Mosaic Model-

Given by- 

 Singer and Nicolson in year 1970.

Cell Composition-

• Proteins - 60-80%
• Lipids - 20-40 %
• Carbohydrates - 2-10 %

Stracture of fluid mosaic model

  

About this model-

• An improved model of the cell membrane was proposed by "Singer and Nicolson" in year (1970), also called Fluid mosaic model.
• 
  
• Fluid nature of cell membrane is imporant for- "Cell growth", "Cell division" and "Endocytosis" Etc.

Transport of molecule via cell membrane-

1- Active transport-

   (Against Cans. gradient)

    Energy requite.

2- Pastive transport-

   (Along Cans. gradient)

    Not requite energy.
