Biophysics Notes PDF

Date: 3rd Feb 2023

In these “Biophysics notes pdf”, we will study the basic facts and ideas of biology from a quantitative perspective. It shows them how ideas and methods of physics enrich our understanding of biological systems at diverse length and time scales. The course also gives them a flavor of the interface between biology, chemistry, physics, and mathematics.

We have provided multiple complete biophysics lecture notes pdf for any university student of BCA, MCA, B.Sc, B.Tech, M.Tech branch to enhance more knowledge about the subject and to score better marks in the exam. Students can easily make use of all these biophysics lecture notes pdf by downloading them.

Topics in our Biophysics notes PDF

The topics we will cover in these Biophysics notes PDF will be taken from the following list:

Overview: The boundary, interior, and exterior environment of living cells. Processes: exchange of matter and energy with environment, metabolism, maintenance, reproduction, evolution. Self-replication as a distinct property of biological systems. Time scales and spatial scales. Allometric scaling laws.

Molecules of life: Metabolites, proteins, and nucleic acids. Their sizes, types, and roles in structures and processes. Transport, energy storage, membrane formation, catalysis, replication, transcription, translation, signaling. Typical populations of molecules of various types present in cells, their rates of production, and turnover. Energy required to make a bacterial cell. Simplified mathematical models of transcription and translation, small genetic circuits, and signaling pathways to be studied analytically and computationally.

Molecular motion in cells: Random walks and applications to biology: Diffusion; models of macromolecules. Entropic forces: Osmotic pressure; polymer elasticity. Chemical forces: Self-assembly of amphiphiles. Molecular motors: Transport along microtubules. Flagellar motion: bacterial chemotaxis.

The complexity of life: At the level of a cell: The numbers of distinct metabolites, genes, and proteins in a cell. Metabolic, regulatory, and signaling networks in cells. Dynamics of metabolic networks; the stoichiometric matrix. The implausibility of life-based on a simplified probability estimate, and the origin of life problem. At the level of a multicellular organism: Numbers and types of cells in multicellular organisms. Cellular differentiation and development. Brain structure: neurons and neural networks. Brain as an information processing system. At the level of an ecosystem and the biosphere: Foodwebs. Feedback cycles and self- sustaining ecosystems.

Evolution: The mechanism of evolution: variation at the molecular level, selection at the level of the organism. Models of evolution. The concept of genotype-phenotype map. Examples.
