Bacterial Cell Physiology Explained | E. coli as a Model Organism

Описание: In this complete lecture on Bacterial Cell Physiology, we explore how bacterial cells function and why Escherichia coli (E. coli) is used as the primary model organism to understand bacterial life processes.

This video provides a structured overview of:

🔬 Core Concepts in Bacterial Cell Physiology
• Nutrient uptake and membrane transport
• ATP generation and proton motive force
• Glycolysis, TCA cycle, and respiration
• Fermentation pathways
• Efflux pumps and antibiotic resistance
• Stress response systems
• Biofilm formation and quorum sensing
• Flagellar motility and chemotaxis
• Binary fission and bacterial growth

🧬 E. coli as a Model Organism
• Gram-negative cell envelope (outer membrane, LPS, periplasm)
• Circular chromosome and oriC
• Plasmids and genetic tools
• Lac operon and gene regulation
• Transcription–translation coupling
• 70S ribosomes
• DNA replication and rapid doubling time

This lecture is designed for:

BS Microbiology students

Biotechnology students

Medical Laboratory Technology students

Competitive exam preparation (NET, GATE, CSIR, etc.)

Anyone seeking strong conceptual clarity in bacterial physiology

By the end of this session, you will understand how bacterial structures enable cellular functions and why E. coli serves as the foundation for molecular microbiology research worldwide.
