Choose each statement$$that supports the conclusion that step $3$ of glycolysis, catalyzed by$$phosphofructokinase $($PFK$),$ is the first committed step of$$glycolysis$.$

Group of answer choices

Glucose$-6-$phosphate from step $1$ can be used for glycogen synthesis

Fructose$-6-$phosphate from step $2$ can be reversed back to glucose$-6-$phosphate

Fructose$-1,6-$bisphosphate has no purpose but to be split in step $4$

Fructose$-1-6-$bisphosphate is a versatile molecule with many fates.
