Which is the correct order of events during auxinmediated ce

Which is the correct order of events during auxin-mediated cell elongation?

	Proton pump gene expression expansin activation ATP hydrolysis H⁺ movement into cell wall
	expansin activation proton pump gene expression H⁺ movement into cell wall ATP hydrolysis
	ATP hydrolysis expansin activation proton pump gene expression H⁺ movement into cell wall
	Proton pump gene expression ATP hydrolysis H⁺ movement into cell wall expansin activation

Which is the correct order of events during auxin-mediated cell elongation?

	Proton pump gene expression expansin activation ATP hydrolysis H⁺ movement into cell wall
	expansin activation proton pump gene expression H⁺ movement into cell wall ATP hydrolysis
	ATP hydrolysis expansin activation proton pump gene expression H⁺ movement into cell wall
	Proton pump gene expression ATP hydrolysis H⁺ movement into cell wall expansin activation

The correct order is :Proton pump gene expression ATP hydrolysis H+ movement into cell wall expansin activation

Reason:Auxin first stimulates proton pump gene expression that together with ATP hydrolysis releases hydrogen ions into the cell wall.This reduces the pH of the cell wall and activates expansin enzyme.Expansins then loosens the cellulose of the cell wall allowing the cell to elongate.
