The release of pyrophosphate from the incoming nucleotide, and then hydrolysis of the pyrophosphate to inorganic phosphate provides energy for the addition of nucleotide onto a DNA strand.
Nucleotides are linked together by a condensation event that yields a tiny, stable molecule. But the released molecule is pyrophosphate, not water. A good amount of free energy is released when water is added to pyrophosphate.
The high-energy link between the ejected beta and gamma phosphates stores the energy for each incoming nucleotide's addition. The subsequent hydrolysis that occurs drives the process. A substantially greater quantity of energy is released when two phosphates are separated into individual phosphates.

Answer:
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail.
Explanation:
 a celestial object consisting of a nucleus of ice and dust and, when near the sun, a ‘tail’ of gas and dust particles pointing away from the sun.
Answer:
A. C-1
Explanation:
During the pentose phosphate pathway, glucose 6-phosphate is first converted into 6-phosphoglucono-lactone in the reaction catalyzed by glucose 6-phosphate dehydrogenase. The 6-phosphoglucono-lactone is then converted into 6-phospho-gluconate which in turn undergoes decarboxylation to form D-ribulose 5-phosphate and the C-1 of original glucose 6-phosphate is released in form of CO2.
Therefore, to observe the most rapid production of labeled carbon atom in form of CO2, the C-1 of glucose should be labeled.
