Last Answer : The chemical equation of the chemical equilibrium of the formation of bicarbonate having as reagents carbon dioxide and water is as follows: CO2 + H20 --> H2CO3 --> H+ + HCO3- The reaction is catalyzed by the enzyme carbonic anhydrase present in red blood cells.
Description : The enzyme which catalyzes the unwinding of DNA helix during replication is: (1) Primase (2) Topoisomerase (3) Helicase (4) DNA polymerase
Last Answer : (3) Helicase Explanation: A type of helicase enzyme called DNA helicase catalyzes the unwinding of the DNA helix at the time of replication. It uses the energy released through hydrolysis of ATP ( ... The enzyme is needed to separate the two strands of DNA also during transcription and DNA repair.
Description : In the metabolic pathway, ABCDE, discuss what effect molecule E would likely have on regulating the enzyme that catalyzes the reaction of A to B?
Last Answer : E is the product. If there is enough of molecule E to complete a chemical process, for example, the molecules (reactants) ABCDE will not be needed, and therefore an excess of E means less of ABCDE produced.
