In the absence of Delta, 

TM subunit of Notch on the surface of a responding cell is non-covalently associated with its extracellular subunit; extracellular domain is folded

Folded extracellular domain cannot

be cleaved by the cell-surface ADAM 10.

ADAM 10 is a matrix metalloprotease, a member

of a class of metal-containing enzymes that cleave the

extracellular segments of target proteins.

ADAM is an abbreviation for a disintegrin and

Metalloprotease (disintegrin is a conserved protein domain that binds integrins and disrupts cell-matrix interactions)

Binding of Notch to Delta 

is followed by endocytosis of Delta by the signaling cell

The force accompanying the movement of Delta into the signaling cell stretches the Notch protein on the responding cell and allowing access by ADAM 10, which cleaves the Notch extracellular domain
