Microbial Structuresa. The Macromolecules that make up MicrobesV. Intro to MacromoleculesOutline of Current Lecture VI. Functions of Carbs and ProteinsVII. Prokaryotic Structuresa. Cell membraneb. Cell wallVIII.Gram StainingCurrent LectureVI. Functions of Carbs and Proteinsa. Carbs: supply energy and energy storage. Are used for energy storage and provides structureb. Proteins: used in cellular rebuilding/repair. They provide transport, function as enzymes, environmental sensing, provide structure (collagen)VII. Prokaryotic Structuresa. Cell membrane: provides a semi permeable barrier. Additional functions includetransport, secretion, environmental sensing, energy acquisition. b. Cell Wall: protects against osmolysis in plant cells. Animal cells will burst, but bacteria have a cell wall preventing them from bursting. It also confers shape and rigidity to the cell and with stands turgor pressure. c. Most bacterial cell walls are made of peptidoglycan.i. Glycan chains are composed of alternating N-acteyl glucosamine and N-acetyl muramic acid. A short peptide bridge links the glycan chainsVIII. Gram Staininga. Gram positive or negative refers to outward structureb. Gram positive has a thick cell wall (peptidoglycan) and 1 cell membraneThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.c. Gram negative has an outer and inner cell membrane and small layer of
