Confusion: One EFI/GPT per system, each disk, or each partition?

After reading through a few explanations online, I'm still unclear on something super fundamental. And not grokking fundamental stuff utterly annoys me.

I currently have the following two drives:

Drive 0 -- C: Formatted EFI/GPT (Win10pro)
Drive 1 -- D/E/F: Older, F: formatted NTFS back before EFI existed---simple storage only. No OS's on D/E: yet. Soon Kubuntu & some other Linux on D and E using EXT4, but that may be an unneeded detail.​

The question I have is this: Since the MBR is not part of the boot to Win10pro any longer, if I someday want to boot to D and E using UEFI:

1. Do each partition need to be formatted separately as EFI/GPT?
2. Or is the GUID Partition Table as it sounds (to me): A partition table per disk?
3. Or is the EFI/GPT concept only one per entire system, such that on bootup, lacking an MBR, it can find all the other GPT partitions?

Thanks!

Nevermind, I received an answer elsewhere.

My supposition of #2 was actually correct.

I would have deleted my question, but there doesn't seem to be any option to do so that I can find.
