BIOLOGY 207 Lecture Notes - Lecture 6: Great Oxygenation Event, Chitin, 18S Ribosomal Rna
Document Summary
Protect us from pathogens simply by taking up space: microbes boost the immune system. Bacteria bind to immune cells and stimulate them to divide and reproduce: microbes protect us from auto-immune diseases. Microbes help train your immune system: microbes keep us slim. Microbes help us digest and ferment foods, and shape our metabolic rates: microbes detoxify and may even ght off stress. Microbes in and on us take in toxins and spare us their dangerous effects: microbes keep babies healthy. Babies born via c-section have very different microbiomes. More likely to develop allergies and asthma than children born vaginally. Microbes are essential for life on this plant: global carbon cycle. Many bacteria, like plants, can use co2 for growth. Bottom of the food chain: global nitrogen cycle. Soil bacteria convert nitrogen into a form plants can use for growth: oxygen. Cyanobacteria were responsible for the great oxidation event 2. 5 bya: clean our environment.
