Question

21. The fluid in blood vessels and the Interstitial space is referred to as: a. The extracellular fluid compartment b. Plasma c. The Intracellular fluid compartment 22. Why is the resting cell membrane more permeable to K+ than to Na+? a. Because gated K+ channels are always open. b. Because K+ can diffuse through the phospholipid bilayer of the resting cell membrane and Na+ cannot. c. Because the cell membrane contains Leak (ungated) K+ Channels. 23. Lipid soluble molecules, carbon dioxide, oxygen and urea are transported across the phospholipid bilayer of the cell membrane by which of the following? a. Simple diffusion b. Osmosis c. Facilitated diffusion d. Active transport 24. The transport of ions across a cell membrane from an area of high concentration to low concentration requires which of the following? a. ATP b. Water c. Carriers d. lon specific Channels 25. Na+ and Glucose are co-transported across the apical epithelial membrane of the small intestines and kidney tubule by which of the following types of transport? a. Primary active transport using a Na+/Glucose ATPase pump b. Facilitated diffusion c. Secondary active transport using a SGLT symport 26. The facilitated diffusion of glucose through GLUT 4 transporters on skeletal muscle cells occurs a. During periods of hypoglycemia and is mediated by the action of glucagon b. During and shortly after meals (Fed State) when blood glucose levels are elevated and is mediated by the action of insulin c. During periods of hyperglycemia and is mediated by the action of glucagon

Answer 1

Answer: 2 21). Fluid in blood space is referred compartment 27777777 vessels and the interstitial to as extracellular fluid oniin 2.2). Resting cell membrane kt than Nat: Because always open. is more permeable to gated &t channels are -23). Lipid Soluble molecules, carbon dioxide , oxygen. and urea are transported across the phospholipid bilayer of cell membrane by simple diffusion 24) Transport of ions across cell membrane from high concentration to low concentration requires ion specific channels 26). facilitated diffusion of glucose through GLUTA transporters on Skeletal muscle cells occurs during and after meds: when blood glucose levels are elevated and mediated by action of insulin.
