Verified
During enzyme-linked reception, signal molecules bind to two tyrosine kinase receptors. The receptor proteins move closer together in the plasma membrane and pair, forming a(n) ____.
A) gate
B) dimer
C) pathway
D) polypeptide chain
E) protein kinase cascade
Tyrosine Kinase Receptors
A type of enzyme-linked receptor on cell surfaces that phosphorylates tyrosine residues on target proteins, playing key roles in cell signaling.
Protein Kinase Cascade
A series of protein kinases that sequentially phosphorylate and activate each other, leading to the amplification of a cellular signal.
Dimer
A molecular complex formed by two, usually identical, molecules joined together.

Final Answer :
B
Explanation :
During enzyme-linked reception, when signal molecules bind to tyrosine kinase receptors, the receptor proteins dimerize, meaning they pair up to form a dimer. This is a crucial step in the signal transduction pathway that leads to cellular responses.
