Answer:
If the active site is altered, the enzyme can no longer perform its catalytic activity
Explanation:
Changes in temperature or pH alters the structure of the enzyme. Enzymes have catalytic activity that lowers the activation energy required for a reaction to proceed.
Enzyme catalytic activity is facilitated by the active site - a specific region of the enzyme where the reactants bind.
At the active site, the conditions are optimal for the reaction to take place (the active site gets the reactants in the perfect position to make contact and react).
If the structure of the active site is compromised, it won't have catalytic activity anymore and won't be able to catalyze the reaction

f. low
Explanation:
Resorption is the loss of substance from any mineralized tissue, mediated by cellular and humoral systems of their own. The four mineralized tissues of our economy, bone, cement, dentin (mineralized fraction of the dentino-pulp functional complex) and enamel, offer different degrees of resistance to resorption. The bone has the greatest lability and the enamel the least. The fact that the bone tissue is the least resistant to resorption is used to move and reposition teeth by controlled forces (orthodontics); and the fact that the enamel is the most resistant has led to think that it does not suffer from resorption.
Osteoclasts They are the spring cells par excellence; they belong to the lineage of the monocitomacrophages. They are large, multinucleated mobile cells, with a clear area and a rough brush border that live for about two weeks and disappear by apoptosis (cell death programmed by fragmentation in membrane particles that allows their phagocytosis without inflammation). They are responsible for the destruction of the organic and inorganic parts of the mineralized bone fraction. They are active both in the processes of the physiological renewal of the bone and in those of its pathological loss.
