One of the major categories of receptors in the plasma membrane reacts by forming dimers is

Receptor tyrosine kinases (RTKs)

Explanation:

Receptor tyrosine kinases is one of the major categories of receptors in the plasma membrane, it reacts by forming dimmers, phosphate groups are also added, and lastly the relay proteins will be activated.

Receptor tyrosine kinases helps in the following cellular processes;

- Motility

- Growth

- Metabolism

- Differentiation.

Receptor tyrosine kinases.

Explanation:

Receptor Tyrosine Kinases are cell surface receptors that are attracted to or have an high affinity for hormones, certain growth factors and cytokines that are present in the body.

Receptor Tyrosine Kinases are also known transmembrane receptors. They are activated by signalling mechanisms or pathways.

The particular molecule ( i.e. hormone, growth factors or cytokines) that requires the used of a Receptor Tyrosine Kinases sends a signal which then causes the Receptor Tyrosine Kinases to bind to the surface of the molecules causing a series of reactions to take place in the cell.

Receptor Tyrosine Kinases are very essential and important for:

a. Cell growth

b. Cellular differentiation

c. Cellular metabolism

d. Cellular survival

e. The multiplication or increase in the number of cells also known as proliferation

Receptor Tyrosine Kinases reacts by forming dimers.
