How many atp molecules are added to get glycolysis started
romanna [79]

Answer:

2 ATP

Explanation:

2 ATP is required to get the glycolysis started. The glycolysis process is divided into two parts, the first part is called the preparatory phase in which energy is required and the second part is called the payoff phase in which energy is produced.

During the first phase in the first step during the conversion of glucose to glucose six phosphate one ATP is consumed and in the third step during the conversion of fructose 6 phosphate to fructose 1,6 biphosphate one more ATP is consumed and in the second phase, 4 ATP is produced.

Therefore the net gain is 2 ATP because 2 ATP are added to get glycolysis started.
