I am told (but have not verified for myself) that when you flash the BIOS on a system using a firmware TPM, you loose the keys and need to supply your recovery key one first reboot after the update. No big deal, just something to be aware of.
As an actual BitLocker user I have also provided actual experience on this many times in this thread.
And yes, when you update the BIOS, upon first boot you will need to verify you are the authorized user of the encrypted drive by providing the BitLocker key or password. The BIOS will then remember this and you won't be asked for the key/password again until the next update or hardware change.
Speaking of which, be aware that certain hardware changes changes like CPU, RAM, MB, or even major BIOS tweaks can cause BitLocker to throw a challenge where you'd need to provide your key or password. Been there done that as well.
