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.

tephra-rock fragments and particles ejected by a volcanic eruption

epicenter-the central point of something, typically a difficult or unpleasant situation

fault-an extended break in a body of rock, marked by the relative displacement and discontinuity of strata on either side of a particular surface

surface waves- mechanical wave that propagates along the interface between differing media

body waves-A body wave is a seismic wave that moves through the interior of the earth, as opposed to surface waves that travel near the earth's surface. P and S waves are body waves.
