AQA A LEVEL BIOLOGY PAPER yst. [3 marks] . 2 Scientists investigated the action based on the enzyme ATP synthase. They made reaction mixtures each containing: • ATP synthase • buffer (to control pH) • substrates. One based on the substrates required within these reaction mixtures is inorganic phosphate (Pi). Tick ( ) one box to show which other substrate the scientists must add to the reactionmixtures to produce ATP. [1 mark] Adenine Adenosine diphosphate Glucose Ribose
