Document Summary
Take home message: fungi can be parasitic or predatory (e. g. plant parasitic fungi, athlete"s foot, cowboy fungi) Exocytosis available if needed to expel waste. Membranes are negatively charged, in order for them to be fused together by . The molecular biology of phagocytosis in protozoans can be complicated. An example showed that there were 85 different proteins involved in the process in a genus that infects up to 10% of people. Phagocytosis is also important in vertebrates: important in the immune system, phagocytosis takes place to destroy the virus (white blood cells) Important: various proteins and ca++ are involved: calcium positively charged help neutralize negatively charged membranes. So we protect ourselves from microbes using phagocytosis, but some microbes have evolved mechanisms to try to escape phagocytosis. Bacteria called streptococcus pneumonia creates a slippery carbohydrate coat to avoid phagocytosis by white blood cells.
