Cardiac muscle fibers function is to contract the heart.
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.
I believe that the areas are tropical and polar zones.
I think the correct answer from the choices listed above is option C. Cells in multicellular organisms differentiate as they continue to divide and increase in size because cells will now perform special functions and have become different to other cells. Hope this answers the question.
Ribosomes make proteins inside a cell.
