PPT-Lecture 2: Molecules and Membranes

The oldest fossils date to 3538 bya How did life originate Reductionism would suggest that the components of lifemoleculeswould have had to form first Lets meet them and then see how they form.

The fetal membranes are normally expelled during the third stage of labor.. The membranes are said to be retained whenever the . third stage of labor is prolonged. They are insoluble in water and highly soluble in one or more of the following solvents: ether, chloroform, benzene and acetone. . Make up about 5% from organic substances which enter in the structure of living cell .. Module 1: Components a nd Architecture o f Cell Membrane Learning objectives: In this module, prime focus is mainly on the plasma membrane, however, majority of the concepts discussed below are also
