Following changes occur during the maturation process of lysosome, except?

#Unit 2. Cellular Organization

The endosome changes shape and location, as the tubular domains are lost and the vacuolar domains are thoroughly modified.
Rab proteins, phosphoinositide lipids, fusion machinery, and microtubule motor proteins all participate in a molecular makeover of the cytosolic face of the endosome membrane.
A V-type ATPase in the endosome membrane pumps H⁺ from the cytosol into the endosome lumen and acidifies the organelle.
Decreasing acidity that accompanies maturation renders lysosomal hydrolases increasingly more active.
