    During glycolysis glucose is phosphorylated and then turned into two triose phosphates, each with one phosphate molecule attached. So how come later on each triose phosphate creates two ATP molecules even though there was only one phosphate molecule available. Please help! I don't know if I'm just completely missing the obvious or not.

    The phosproylation occurs in two steps.
    Wherby ATP is converted to ADP to make glucose-6-phosphate.
    Again ATP is converted to ADP to make hexose-1,6-bisphosphate.

    During oxidation of the troise sugars. each make 2 ATP molecules from 2 ADP molecules.
    There is therefore a net gain of 2 ATP molecules at the end of glycolysis
