Energy Coupling and Phosphorylation
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Energy coupling pairs ATP hydrolysis with an endergonic reaction, often by phosphorylation — transferring ATP's terminal phosphate onto another molecule.
Show
The sodium-potassium pump from Bio 0362 is phosphorylated by ATP, and that transfer drives the conformational change moving sodium and potassium.
Watch for
The energy does not leap to the second reaction — phosphorylation physically links the two.
