Question

During the second half of glycolysis, what occurs?

a. ATP is used up.

b. Fructose is split in two.

c. ATP is made.

d. Glucose becomes fructose.

Short answer

ATP is made during the second half of glycolysis . Therefore option c is the correct answer.

Step-by-step solution

Concept Introduction

Glycolysis remains an anaerobic technique for the decay of glucose into pyruvate. This operation occurs in the cytoplasm in both prokaryotes and eukaryotes. Glycolysis implicates two stages. The principal stage is the underlying stage wherein energy is expected while the subsequent stage is the result stage in which energy is discharged.

First Half of Glycolysis

Glucose-6-phosphate structures fructose-6-phosphate by isomerization which is then phosphorylated utilizing ATP and structure fructose-1,6-bisphosphate.

Fructose-1,6bisphosphate formations two three-carbon isomers i.e., glyceraldehyde-3-phosphate and dihydroxyacetone phosphate. Therefore a, b , and d are the incorrect answers.

Second Half of Glycolysis

The second half of glycolysis is even learned as the payoff or energy-releasing stage because, during this step, the two ATP molecules implanted during the first stage are delivered back along with the exhibition of two more ATP molecules and two (lowered nicotinamide adenine dinucleotide) molecules. Therefore option c is the correct answer.
