Question

each of the following molecules is processed by glycolysis to pyruvate. how much net atp is generated starting with each molecule

Answer 1

From glucose $2$ ATPs are produced.

ATP:

• One glucose molecule is divided into two pyruvate molecules during glycolysis, requiring two ATP molecules while generating four ATP molecules and two NADH molecules.
• For the cell to utilize as energy, glycolysis results in a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules.
• Glucose breaks down into pyruvate and energy during glycoses
• From glucose 6- phosphate to lactate 3 ATPs are produced.
• $4$ ATPs are generated from which one is utilized when fructose $6$ phosphate is converted to fructose $1, 6-$ bisphosphate. So the net yield is $3$ATP.

From dihydroxyacetone phosphate 2 ATPs are produced.

As the cycle occurs only once either from DHAP or PGAL (glyceraldehyde $3-$ phosphate)

Three irreversible reactions of glycolysis:

Hexokinase

Glucose + ATP$\rightarrow$ Glucose$-6-$phosphate + ADP

Phosphofructokinase-I

Fructose$-6-$phosphate + ATP $\rightarrow$ Fructose$-1, 6-$bisphosphate $+$ ADP

Pyruvate kinase

$\mathrm{PEP}+\mathrm{ADP} \rightarrow$  Pyruvate $+$ ATP
