Final answer:
Coiled coil tethers form the Golgi matrix through homodimerization, heterodimerization, homotrimers, and heterotrimers, providing structural versatility and stability.
Step-by-step explanation:
The four ways coiled coil tethers form the Golgi matrix are homodimerization, heterodimerization, homotrimers, and heterotrimers. These tethers help establish and maintain the Golgi apparatus structure by allowing proteins to form complexes of various sizes and compositions. Homodimerization involves the pairing of two identical subunits, while heterodimerization involves the pairing of two different subunits. Homotrimers are made up of three identical subunits, and heterotrimers are made up of three different subunits. The diversity of these combinations contributes to the functional versatility and stability of the Golgi matrix.
