Addition of a nucleotide onto a dna strand is an endergonic reaction. what provides the energy to drive the reaction?

Biology

Kruka [31]2 years ago

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.

Photosynthesis and cellular respiration, look at the picture
Anika [276]

Mike discovered that the  product of cellular respiration are the raw materials  of Photosynthesis while the products of photosynthesis  served as the raw materials for cellular respiration.

He also discovered that respiration is a catabolic process while photosynthesis is an anabolic process.

Another interesting fact seen by Mike is, the respiration releases energy while photosynthesis takes in energy.

Explanation:

  • In the equation of cellular respiration , we can see that glucose and oxygen are utilized in the mitochondrion to produce  carbon dioxide , water and chemical energy in the form of ATP.
  • Glucose breaks down during cellular respiration .
  • Again if we look at the chemical equation for photosynthesis in the chloroplast, we find that Carbon dioxide,which was produced during respiration is utilized along with water in presence of light energy to give out oxygen and Sugar (glucose)

Explain the meaning of the symbols as they are used in this expression.
Dmitrij [34]

Answer:

  • A, B, C and D are: elements or molecules
  • A and B are: reactants
  • C and D are:  products

Explanation:

The expression "A + B <--> C + D" represents a chemical equation. A chemical equation represents the "mixture" of molecules or elements that will react and form other molecules and elements, so we can say that A, B, C and D represent molecules or elements.

But not only that. In a chemical equation, the elements and molecules that are before the symbol "<-->" represent the reagents in the equation. Therefore, A and B are the reagents. The elements or molecules found after the symbol "<-->" are the products of the reaction. Therefore, C and D are the products.
