Answer:

During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi --> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O).

Hope this will help u ✨️♥️

Answer:

there are two equations representing the production of ATP during the process of glycolysis, along with sentence explanations:

Equation 1:

Glucose + 2 NAD+ + 2 ADP + 2 P(i) → 2 Pyruvate + 2 NADH + 2 ATP + 2 H2O

In this equation, one molecule of glucose is broken down into two molecules of pyruvate. During this conversion, two molecules of NAD+ (Nicotinamide adenine dinucleotide) are reduced to form two molecules of NADH (Nicotinamide adenine dinucleotide, reduced). Additionally, two molecules of ADP (Adenosine diphosphate) combine with two inorganic phosphate groups (P(i)) to produce two molecules of ATP (Adenosine triphosphate). This reaction occurs in the cytoplasm and represents the first half of glycolysis.

Equation 2:

2 ADP + 2 P(i) → 2 ATP

In this equation, two molecules of ADP (Adenosine diphosphate) react with two inorganic phosphate groups (P(i)) to produce two molecules of ATP (Adenosine triphosphate). This reaction occurs during the second half of glycolysis, where the energy-rich molecules NADH generated in the previous steps are used to convert pyruvate into either lactate or acetyl-CoA, depending on the presence of oxygen.

These equations illustrate how ATP is generated during glycolysis, which is the initial stage of cellular respiration and a vital process for energy production in cells.
