Enzyems are highly selective catalysts.
Receptors are not very highly selective catalysts.
When a receptor protein acts as an enzyme, the receptor protein activates a second messenger that acts as a signal molecule within the cell. Resources: HOLT Biology Textbook - 9th grade edition Chapter 4, Cells and Their Environment.
A ligand is a molecule that binds to a receptor protein, while a receptor protein is a protein that recognizes and binds to specific ligands, triggering a biological response. Simply put, a ligand is like a key that fits into a receptor protein like a lock, initiating a signaling cascade in the cell.
A noncompetitive inhibitor binds to an enzyme at a site other than the active site, while an allosteric inhibitor binds to a different site on the enzyme, causing a change in the enzyme's shape and reducing its activity.
An allosteric inhibitor binds to a site on the enzyme that is different from the active site, causing a change in the enzyme's shape and reducing its activity. A noncompetitive inhibitor binds to either the enzyme or the enzyme-substrate complex, also reducing enzyme activity but without directly competing with the substrate for the active site.
pinocytosis is a non-specific process where the cell engulfs extracellular fluid and particles, while receptor-mediated endocytosis is a selective process that relies on specific receptors binding to ligands for internalization. Receptor-mediated endocytosis is more efficient and targeted compared to pinocytosis.

A nonenzymatic reaction doesn't use an enzyme.

Antibodies lack a transmembrane domain.

co factor helps the factor in reaction and co enzyme helps the enzyme only
enzyme is a kind of protein that catalyzes specific reactions & abzymes are antibodies that target the transition state of an expected reaction.

A Receptor is referring to a sense organ, like a nerve ending. An Effector is referring to a muscle capable of reflecting to a stimulus. By definition, receptor and effector are antonyms.
No. It is a beta-1 receptor blocker, and an inhibitor of angiotensin converting enzyme (ACE).
Both enzymes and receptors have specific sites for the substrates to bind. The receptor causes a response beyond the cell membrane and the enzyme facilitates a chemical change in the substrate. Enzymes can be membrane bound or free floating. Receptors are usually membrane proteins
Rennin : It is an enzyme (protein) secreted by kidneys to regulate the blood pressure. It's a digestive enzyme in gastric juice. Renin :It is a hormone.
