Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cell surface receptors may be any of the following except
A
G protein linked
B
Enzymic receptors
C
Single-pass transmembrane proteins for neurotransmitters
D
Chemically-gated ion channels
Explanation: 

Detailed explanation-1: -Cell-surface receptors come in three main types: ion channel receptors, GPCRs, and enzyme-linked receptors. When a ligand binds an ion channel receptor, a channel through the plasma membrane opens that allows specific ions to pass through.

Detailed explanation-2: -G-protein-coupled receptors (GPCRs) are the largest cell surface receptors, composed of 7 transmembrane proteins in the plasma membrane.

Detailed explanation-3: -1-Intracellular receptors (also called as internal receptors) are found within the cytoplasm of the cell and thus they are not a type of cell surface receptor.

Detailed explanation-4: -Transcription Factors. Eicosanoid Receptor. G Protein. Receptor Tyrosine Kinase. Cell Signaling. Extracellular Matrix. Integrin. G Protein Coupled Receptor. More items
