Explanation / Answer
Ans.
I. Apyrase: e. Eliminated unincorporated nucleotides and ATP.
The enzymes hydrolyze ATP and other NTP into ADP (or, NDP) and AMP (or, NMP) subsequently. Here, N = Nitrogenous base in general. Hydrolysis of nucleotides cause their elimination as energy source from the medium.
II. Luciferase: a. Releases light as a result of luciferin oxidation.
III. DNA polymerase: d. Synthesizes DNA 5’-3-
IV: ATP sulfurylase: b. Substrate is PPi which is used to create ATP
Sulfate + ATP ----ATP sulfurylase ----> Adenosine 5’-phsophosulfate (APS).
However, the enzyme also catalyzes the backward reaction to produce ATP from PPi and APS as follow-
APS + PPi ----ATP sulfurylase ----> ATP
V: Taq polymerase: c. Creates approximately 106 multiple identical DNA products which are attached to each bead. This DNA synthesis is carried out in PCR.
Note that DNA polymerase makes only a single copy of each DNA during replication.
