    What do kinases do

    I looked online and it seems obvious; Kinases add a phosphate group to a molecule, thus converting ATP to ADP. But... in glycolysis, Phosphoglyceratekinase produces ATP. I'm confused af.

    Kinase work in multiple directions?

    Here's my example, pertaining to Glycolysis: Phosphofructokinase adds a phosphate group to the intermediary sugar, but Pyruvate Kinase removes a phosphate group from the intermediary sugar. Thus, what do kinases do? Are their substrates ADP or the actual sugar molecules?
