5. Membrane receptors are specialized proteins that take part in communication between the cell and the outside world. The membrane protein receptor can be
subdivided into three parts or domains. The portion of the protein in the E zone is
extracellular (outside of the cell). The P zone is the plasma membrane and the
zone is intracellular (inside of the cell)

A glucagon hormone is a molecule that stimulates a reaction inside liver cells.
Based on the diagram, where do you think a glucagon hormone most likely binds
to send its signal to the cell?

The E zone portion of the protein

Explanation:

The glucagon hormone which is a signal molecules that triggers a reaction in the liver cells is most likely to bind to the E zone extracellular portion of the G-protein-coupled receptor. This then changes the conformation of the receptor activating the heteromeric G proteins.

children tend to take more after their grandparents more than their parents. it’s the dna you received that was passed down to you somewhere in your family. maybe one of your grandparents had/has straight hair and you might have gotten it from them.
