Advanced Pathophysiology Exam 1 Study Guide with Complete Solutions

Advanced Pathophysiology Exam 1 Study Guide with Complete Solutions What are the properties of a eukaryotic cell - Correct Answer • Well define nucleus. • cells are larger and have more extensive intracellular anatomy and organization than do prokaryotes. • cells bind with deoxyribonucleic acid (DNA) and are involved in the super coiling of DNA. • cells have several chromosomes, protein production or synthesis . it consists of three components: outer membrane called plasma membrane, a fluid filling called cytoplasm, and the intra cellular organs or organelles How do cells communicate with each other and the environment outside the cell - Correct Answer Cells communicate by using hundreds of signal molecules. -they display plasma membrane-bound signaling molecules (receptor) that affect the cell itself and other cells in direct physical contact -they affect receptor proteins inside the target cell and the signal molecule has to enter the cell to bind to them -they form protein channels (gap juctions) that directly coordinate the activities of adjacent cells. responsable for cellular respiration and energy production - Correct Answer mitocondria they provide sites for cellular protein synthesis - Correct Answer ribosome is the largest membrane bound organelle and is usually found in the cell center, main function is cell division and control of genetic information - Correct Answer nucleus is a small dense structure composed largely of RNA and combine it with proteins - Correct Answer nucleolus are saclike structures that originate from the golgi complex and contain digestive enzymes - Correct Answer lysosomes
