Chapter 23, Problem 12RQ
Osteoclasts make acid (H+) from CO2 and H2O. They secrete the acid at their apical membrane and put bicarbonate into the ECF. Draw an osteoclast and diagram this process, including enzymes and the appropriate transporters on each membrane.

- Marathon runners often practice "carb loading" prior to a race. The purpose of this practice is to increase the stores of energy available for muscles to use. Explain how energy is used by muscle fibers and how this practice of "card loading" benefits the runner's muscles. Be sure to use the terms glucose, glycogen, creatine, phosphate, and ATP in the explanation.arrow_forwardSuppose a person had an unusual mutation in the troponin protein of his skeletal muscles, such that the troponin could not bind to calcium.

- Abnormal level of these compounds present in the blood may reveal bone diseases and condition. Choices: Phosphorous and calcium Bicarbonates and chloride Potassium and sodium Creatinine and bilirubinarrow_forward1) Homeostasis requires feedback loops in order maintain relatively constant internal conditions Below, you will find a situation in which homeostasis is being maintained: The human body must work to maintain a relatively constant concentration of Ca2+ in the blood When the blood [Ca2+] drops below normal levels, cells called osteoclasts will release stored Ca by breaking down bone. In order to begin this process, the osteoclasts must first come into contact with PTH; this is how the osteoclasts know when to start breaking down bone tissue. PTH is a hormone that is produced by the parathyroid glands when these glands detect that the blood [Ca2+] has dropped below normal levels. As the release of Ca2+ brings blood [Ca²+] closer to healthy levels, less PTH is secreted, until finally the blood [Ca²*] is back to healthy levels and no PTH is secreted anymore. a) Identify the sensor, control center, and effector in the situation described above.

- Name two metabolic processes, other than bone health and remodeling that require calcium?arrow_forward24. A rare genetic disorder called receptor deficit rickets results in the absence of a working receptor for the active form of Vitamin D in tissues. This lack of receptor results in the "message" of vitamin D being lost. What impacts on bone formation would you predict from this disorder? (check all that apply) Group of answer choices fewer materials for building bone would be delivered via the nutrient artery upregulation of Ca+2 transporters would be limited Ca+2 absorption would be impacted bone density would be decreased chondrocytes would be prevented from creating an alkaline environment osteoclast activity would be suppressed, limiting remodelingarrow_forwardYou are a medical provider in at a clinic. A patient you are seeing complains of muscle weakness, an inability to move or contract. In order to better understand the issue you conduct a lab exam and discover the patient has the condition of hypermagnesemia—a high concentration of magnesium ions in the body fluids—magnesium ions have a charge of 2+ similar to calcium. What do you think is happening here? What can you deduce is the cause of the muscle weakness?arrow_forward
