Question Set 3 1. Briefly describe how respiration is regulated. If the cell is busy and working hard, the level of ATP will decrease, therefore respiration will increase. Once there is a high level of ATP respiration will then decrease. Cellular respiration is regulated by allosteric enzymes at both the citric acid cycle and glycosis. 2. What is an allosteric enzyme and how does it work in the above process? They are enzymes constructed from two or more subunits, each subunit having its own active site. The enzyme functions in either an active or an inactive state. It is inhibited by ATP, making it inactive. As ATP accumulates, inhibition of the allosteric enzyme slows down the process of glycosis. The enzyme then becomes active and converts ATP into ADP faster than ATP is being produced. 3. Why is converting the body’s protein to glucose to use as an energy source detrimental to health? Under what conditions would this occur? Because protein is essential to other functions of the body and those functions
