A biological community of interacting organisms and their physical environment.
Answer:
C
Explanation:
pyruvate dehydrogenase is the enzyme which catalysis pyruvate to acetyl Co -A. Thus,it ensures the formation of link reaction/ bridge reaction for linking glycolysis with Citric acid cycle. Therefore, inhibition of this enzyme, prevent link reaction, and there reduction in pyruvate utilization and therefore prevent the commencements of Citric acid cycle, with consequent reduction in glucose oxidation. as there is no reaction of acetyl Co A (from link reaction from pyruvate ) with 4C oxaloacatate in the kreb Cycle to form Citrate in Kreb's cycle. Thus the heart depends on fatty acid supply for energy.
Answer:
In the case of catalase, the optimum pH is approximately pH 7.0. That is, catalase works best at a neutral pH. If the solution is too acidic (low pH value) or too basic (high pH value) the catalase is inactive and no longer functions as an enzyme.
