What is Synthesis reaction in chemistry

It is a reaction in which multiple reactants combine to form a single product.

Explanation:

A synthesis reaction is one in which a single product is formed by the reaction of multiple reactants. They are exothermic reactions because they release energy and heat along with the product formed. In these reactions, the reactants will be more than the products and the product would be more complex than the reactants. They can be represented as A + B > AB Example: Na (Sodium) + Cl (Chloride) > NaCl (Sodium Chloride)

The answer is:

The conversion of 1 mol of pyruvate to 3 mol of CO2 via pyruvate dehydrogenase and the citric acid cycle also yields 4 mol of NADH, 1 mol of FADH2, and 1 mol of ATP (or GTP).

Explanation:

Conversion of 1 mol of pyruvate to 3 mol of CO2 through the enzyme pyruvate dehydrogenase and by the citric acid cycle produces 4 mol of NADH, 1 mol of FADH2 and 1 mol of ATP.

The reaction is:

pyruvate + CoASH + NAD⁺→ acetylCoA + NADH + H⁺ + CO₂ (1 mol of NADH is released)

3 moles of NADH, 1 mole of FADH2 and 1 mole of GTP are produced in the citric acid cycle. In this way, the number of total moles of NADH that is produced is 4, while FADH2 is 1 and GTP is 1.
