Lecture
This lecture covers the evolution of microscopy, cell wall structures of prokaryotes, membrane-associated proteins, and the functions of cell membranes. It explores topics such as passive and active transport, membrane permeability, and the role of integral and peripheral membrane proteins. The lecture delves into the mechanisms of metabolite transport, focusing on ABC carriers and the hydrolysis of ATP. It also discusses motility and chemotaxis in prokaryotic cells, including the different modes of movement and the importance of chemotaxis in directing cell motion towards or away from chemical signals. Additionally, it examines the concept of 'swarming' in bacterial colonies and the differentiation of morphology and growth rate based on colony position.
