To discuss:
The composition, location, and function of ribosomes.
Introduction:
Cells are regarded as the simplest unit (structural and functional) of life. Cellular membrane, nucleus, and cytoplasm are the three major components of a cell. Cellular membrane, which surrounds the entire cell, is composed of phospholipids and proteins. The nucleus is bound by a nuclear membrane, and it possesses the genetic material of the cell. Cytoplasm consists of organelles, cytoskeleton (filaments and tubules), and inclusion bodies. Organelles are structures present within a cell and are specialized to perform a particular

She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes. Which of the following Plasmodium species is most likely responsible for her severe symptoms? A. Plasmodium vivax B. Plasmodium ovale C. Plasmodium malariae D. Plasmodium falciparumarrow_forward
