Plasma membrane is a lipoproteinous and trilaminar membrane. It regulates the exchange of materials between the cystosol and extra-cellular medium. Give the reasons for the following:
(e) Enlist two differences bewteen passive and active transport.

Plasma membrane is a lipoproteinous and trilaminar membrane. It regulates the exchange of materials between the cystosol and extra-cellular medium. Give the reasons for the following: (a) What do you mean by lipoproteinous and trilaminar nature of plasma membrane?

Plasma membrane is a lipoproteinous and trilaminar membrane. It regulates the exchange of materials between the cystosol and extra-cellular medium. Give the reasons for the following: ( C ) Why the plasma membrane is said a selectively permeable membrane?

Plasma membrane is a lipoproteinous and trilaminar membrane. It regulates the exchange of materials between the cystosol and extra-cellular medium. Give the reasons for the following: (b) Phospholipids are called amphipathic molecules. Why?

A colloidal solution is a type of mixture which consists of particles whose size varies between 1 and 1000 nanometres. In colloidal solution the particles are distributed evenly. During this process the particles do not settle down. This is one of the best know thing about colloidal solutions. Properties of colloids and their variation are a well-known area ever since the primitive age. The best example to prove their familiarity with us is that we know from very early times that coagulation of milk results in the formation of curd. Physical properties of colloids 1. The nature of the colloidal solution is heterogeneous i.e. unlike. These solutions dwell with two different phases : • Dispersed medium Dispersed phase. 2. Despite the fact that colloidal dispersions are unlike in description (nature), yet the dispersed fragments are not detectabJe by the human eye. This is due to the microscopic size of the particles in the solution. 3. The colour of the colloidal dispersion is determined by particles in the solution based on their size. The wavelengths of light that is absorbed will be longer ifthe size of the particle is large. 4. As a result of its size, the colloidal fragments can easily be passed through a traditional filter paper. However, these particles can be filtered by using membranes such as animal, cellophane, and ultrafilters. Give the name of membrane used for filteration ?
