the protein in the milk is denatured, therefore it cannot return to its original structure. the tertiary and quaternary structure of the original protein changes, bonds are broken and others reformed, these cannot be changed. the process is similar to that of cooking an egg, once it has been cooked it cannot change back to its raw state.
due to the presences of lactobacilli organism and with their metabolic activities the process of milk into curd is irreversible. and the curd is a spoiled product of milk by the presence of lactobacilli sps in the open space or closed space.

because it is irreversible and it has a new substance
This is a chemical change.
no change
yes!
Yes, but it is so hard as not to be worth it.
