|
|
Lysosomes digested the protein after it was made
|
|
|
Smooth ER enzymes aren’t working properly and the receptor protein isn’t made properly
|
|
|
The receptor is made by ribosomes but isn’t transported to the membrane

|
|
There are no working ribosomes in the cell

Detailed explanation-1: -Membrane receptors are specialized protein molecules attached to or integrated into the cell membrane. Through interaction with specific ligands (e.g., hormones and neurotransmitters), the receptors facilitate communication between the cell and the extracellular environment.
Detailed explanation-2: -When a signal molecule binds to the receptor protein, the receptor protein speeds up chemical reactions inside the cell. The receptor protein is an example of an enzyme. These substances function to speed up chemical reactions within cells and may sometimes be found embedded in the cell membranes.
Detailed explanation-3: -Cellular receptors are proteins either inside a cell or on its surface which receive a signal. In normal physiology, this is a chemical signal where a protein-ligand binds a protein receptor. The ligand is a chemical messenger released by one cell to signal either itself or a different cell.
Detailed explanation-4: -Many genetic diseases, such as cystic fibrosis, Alzheimer’s disease, and some forms of diabetes, result from mutations in membrane proteins.
