Biomembranes and Bioenergetics

CEC via Swayam


The course Biomembranes and Bioenergetics has a multi-disciplinary application and encompasses core fundamental topics that will benefit students in the fields of life sciences, biochemistry, biophysics, molecular biology, bioengineering, biotechnology etc.The main objectives of the course are:1. To familiarize the students with the fundamental concepts of cellular membranes, their structures and the chemical composition that are responsible for the unique functions of biomembranes with emphasis on membrane transport2. To help the students understand the concept of chemical thermodynamics and how they apply within cells3. To make the students understand the various energy transductions that occur within the cell.
