The solution is therefore choice (2). signaling that depends on contact.
A membrane protein called the Delta protein prevents neighboring cells from differentiating into neural cells. This is accomplished by attaching the Delta receptor to the membrane receptor of the next cell, creating a notch. It is hence a notch pathway.
As the Delta must attach to the membrane protein of the neighboring cell in order to communicate, this pathway is contact-reliant. Juxtacrine signaling, also known as contact-dependent signaling, is a type of cell-to-cell communication.
While paracrine signaling occurs next to cells without coming into contact with them, endocrine signaling occurs over great distances. Neurons play a role in neuronal signaling.

Complete Question :-
During nervous system development in Drosophila, the membrane-bound protein Delta acts as an inhibitory signal to prevent neighboring cells from developing into neuronal cells. Delta is involved in signaling endocrine contact-dependent paracrine neuronal Why does the Na/K* pump become phosphorylated? the pump protein is physically blocking the entry of the various ions into the cell and needs energy from the hydrolysis of ATP to carry out this action the entire pump rotates 180 degrees to deliver the ions to the other side of the membrane, this rotation requires the hydrolysis of ATP the pump protein must move laterally within the membrane and this movement requires energy provided by ATP hydrolysis o generating a gradient requires active transport which is an energy dependent process using ATP hydrolysis You are trying to study the ability of the ER to sort proteins. Specifically, you are interested in a protein called INDY which is a transmembrane protein (shown below).
