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.

1,3 BPG to 3PG is a reversible reaction depending on the energy state of the cell. Phosphoglycerate Kinase and similarly Pyruvate Kinase are named for the reverse reactions.
Kinases move phosphate groups.
Hexokinase/Glucokinase add a Phopshate to Glucose
Phosphofructokinase add a Phosphate to Fructose-6P
Phosphoglycerate Kinase adds a Phosphate to ADP (making ATP) from 1,3-BPG
Pyruvate Kinase adds a Phosphate to ADP (making ATP) from PEP
Hexokinase/Glucokinase add a Phopshate to Glucose
Phosphofructokinase add a Phosphate to Fructose-6P
Phosphoglycerate Kinase adds a Phosphate to ADP (making ATP) from 1,3-BPG
Pyruvate Kinase adds a Phosphate to ADP (making ATP) from PEP
I see so if I see kinase I shouldn't automatically assume it consumes ATP. Make sense, Thanks!

Some enzymes in the pathways are named for the reverse reaction; don't be confused!
