To help you synthesize all you’ve learned to this point, use Le Chatelier’s principle to hypothesize why the formation of H2CO3 is occurring in the osteoclast.
Homework Answers
Le Chatelier’s principle states that if a system at equilibrium is exposed to stress the system will shift to relieve that stress. When stress is created due to absorption of calcium from bones, this activates the osteoblast species which starts producing osteoid, the organic component of bone.
The osteoclast releases the hydrogen ions through the action of anionic anhydrase (H2O + CO2 → HCO3− + H+) acidifying and helping dissolution of mineralized bone matrix to Ca2+ ,H3PO4, H2CO3. This minaralized matrix is absorbed by osteoclast.

Select all of the following that are true about disturbing an equilibrium (Le Chatelier's principle). When an equilibrium is disturbed by adding an additional amount of one of the reactants, the system will response by making more products. When an equilibrium reaction is disturbed by adding more of one of the products, it will shift toward the reactants to return to equilibrium. All of the concentrations will change, but it will return to the same original value of Keg....

Learning Goal: Develop problem-solving skills wing chemical equilibria and oplying Le Chatter's principle Solving problems with chemical equilibrium If you know the basic principles of chemical equilibrium, you can analyze and predict reversible reactions. To analyze any reversible reaction, follow these problem-solving steps: 1. Identify the reactants and products for the given chemical reaction. 2. Draw a diagram of the reaction to better understand what is happening 3. Identify how increasing or decreasing a product or reactant stresses the equilibrium...

Do no leave any blanks. If you need fewer than five elementary matrices, fill the remaining spaces with identity matrices You may want to adjust the width of your browser window so that all matrices fit on one line
