Head coach Sean Lineen made eight changes from the side which beat Newport Gwent Dragons last Friday night for the trip to the south of France.
Among the starting XV named yesterday, all but two were included in the squad announced by Scotland coach Andy Robinson on Wednesday to train in St Andrews ahead of next month's opening Six Nations games against France at Murrayfield and Wales in Cardiff.
Lineen, whose side cannot qualify for the quarter-finals, said: "The players enjoy going over to France. We ran Biarritz close at Firhill and now have the opportunity to make amends.
"Training has been going well this week. Biarritz are an incredibly hard team to beat. They have some quality players so we need to make sure our discipline is good and we deal with their kicking game."
Four of the eight changes were in the pack as internationals Dougie Hall, Moray Low, Alastair Kellock and John Barclay were selected for what will be their final club match before the Six Nations. They replace Fergus Thomson, Ed Kalman, Dan Turner and Calum Forrester respectively. Kelly Brown reverts to blindside flanker due to the return of Barclay.
In the backs, Graeme Morrison returns at centre, where he partners Max Evans. As a result, Rob Dewey is moved to the right wing where he takes over from DTH van der Merwe, who is ruled out due to a calf injury.
At half-back, Scotland captain Chris Cusiter and Dan Parks are both selected ahead of Colin Gregor and Ruaridh Jackson.
The French have already won the group, but a bonus-point win over Glasgow would confirm home advantage in the quarter-finals, so they have plenty to play for.
Biarritz have failed to make the quarter-final stage since going all the way to the 2006 final in Cardiff and England internationalist Ayoola Erinle is adamant there will be no complacency at Parc des Sports Aguilera.
"Glasgow are flying high in the Magners League and they've got a lot of confidence," said the former Wasps wing and 2004 Heineken Cup winner.
"When we played them at their place in round one it was one of the few away games where we actually stuck to our game plan and were well structured.
"We know that they play with good width and they keep the ball well so we'll have to be on our mettle. Even though we're at home, we won't be taking anything for granted.
"Biarritz are a club who want to perform more consistently in the upper echelons," said Erinle.
"I have experienced that with Leicester and with Wasps and it's something I'd like us to do. So the win on Sunday is paramount and when you start chasing bonus points without securing the win, then you can come unstuck quite easily.
"Our first and over-riding thought will be to win the game. If we can achieve that then we'll look at the bonus point."
