The full-back was fouled for the penalty that allowed West Brom's Craig Dawson to slot home the only goal of the game at Norwich's Carrow Road.
Adam was joined in the starting line-up by Steven Caulker and Danny Rose as we provided three of the back four, alongside centre-back Dawson.
We later had four players on the pitch as Andros Townsend was introduced for Liverpool's Raheem Sterling in the 66th minute.
That was the winger's first cap at Under-21 level and he certainly helped the Three Lions gain imputus in the final quarter of the game.
The key moment arrived a minute before his arrival though.
Adam did well initially down the right, his cross was cleared back to him and as he drove into the penalty area, he was upended by Serbia's Luka Milunovic and Dawson slotted home comfortably from the spot.
Our players were involved in some of the key action as England created chances throughout.
Danny provided an inch-perfect cross for Thomas Ince in the first half, only for the Blackpool winger to head wide from close range.
Steven then made his presence felt in the attacking third, winning a key header to allow Jordan Henderson to fire straight at Serbia goalkeeper Branimir Aleksic.
Andros helped set-up a great chance for Wilfried Zaha, but the Palace man fired wide and later curled in a free-kick that Steven looked to have buried, only for Aleksic to claw his header out.
The lads face the return leg in Serbia on Tuesday night - the winners qualify for the finals in Israel next summer.
