Objective: 
This course will enable the students to –
1. Formulate basic concepts of cellular structure and function covering all the components of prokaryotic and eukaryotic cells, especially macromolecules, membranes, and organelles.
2. Investigate an account of the complex regulatory mechanisms that control cell functions therefore it will help students to understand how these cellular components are used to generate and utilize energy in cells.
