Exam (elaborations) GMS6440: Fundamentals Exam Review

Filtered wastes from the glomerulus will move in the following order: Bowman's capsule-proximal tubule-distal tubule-loop of henle- collecting duct. (True/False) - False. Bowman's capsule- proximal tubule- loop of henle- distal tubule- collecting duct. Specificity of hormone action in the target cells is determined by receptors. (True/False) - True. The area of nerve axon not wrapped by myelin sheath is called the nodes of Rnavier where action potential is insulated. (True/False) - False. Myelin sheath insulates action potential. Action potential propagates faster by skipping myelinated axon, and jumping from nodes of Ranvier to another node. What chemical component of the plasma membrane prevents ions from readily and freely moving across the membrane? - Lipids (phospholipids) Where is the concentration of [K+] greater? Cytoplasm or extracellular fluid? - Cytoplasm Across a cell's plasma membrane, movement of water is (passive through a channel or an active event)? - Passive through a channel Where is the concentration of [Na+] greater? Cytoplasm or Extracellular fluid? - Extracellular fluid Regarding secondary active transport of glucose, the movement of glucose is from a compartment of high concentration to low concentration. (True/False) - False, it moves into the cell with sodium from low to high c
