When a signal molecule such as a growth hormone binds to a receptor protein in the plasma membrane it stays on the outside of the cell. How might the inside of the cell know that the signal has bound?
Due to a conformational change of the receptor protein....
What are important tissue receptor tumor markers?
estrogen receptor, progesterone receptor, interleukin-2 receptor, and epidermal growth factor receptor.
Growth factor hormones such as insulin bind to which type of receptor?
tyrosine kinase receptor!!
What are the names of the peritoneal membranes?
The main importance of membrane proteins is its specific functions. The amount of proteins in membranes varies from 25 to 75% of the membrane constitution. The amount and types of membrane proteins are highly variable. To give a few examples: In plasma membrane , there are transmembrane proteins associated with lipids, either "single" or "multipass" proteins. Examples of this kind of proteins are the porins (present in different types of bacteria) and membrane receptors that react with antigens triggering signal transduction cascades to the cell interior in order to generate a cellular response (e.g., insulin growth factor recepetor or IGFR, fibroblast growth factor receptor or FGFR, nerve growth factor receptor or NGFR, plateled-derived growth factor receptor or PDGFR, etc.). On the other hand, we have the spectrin, a cytoskeletal protein noncovalently associated with the cytoplasmic side of the erythrocyte cell membrane. Also, we have the glycophorin A in erythrocyte plasma membrane, however with an uncertain function. In mitochondria, the are several kind of membrane-associated proteins, such as cytochromes, crucial for electron transport during "cell respiration". In bacteria, we found the bacteriorhodopsin, with light-absorbing activity.
The receptor for a group of signaling molecules known as growth factors are often?
receptor tyrosine kinases
How does glucose enter blood cells to synthesize ATP?
This is a typical muscle cell, you the insulin receptor at the top of page within the membrane of the cell. That insulin receptor sends a signal over to the Glut 4 glucose channel in the membrane to the left of the insulin receptor in which sugers enter the cell. The insulin hormone also sends many signals all over the inside of the cells cytoplasm, and into the nucleus on the bottom of page where transcription of genes takes place. In this case a growth hormone is made from a gene, and that growth hormone regulates the insulin and thereby the uptake of glucose into the cell. A type of negative feedback inhibition loop system, so the cell doesn't get too much intake of suger. That growth hormone controls this from happening. David Hagert Researcher medical

What is the name of the gene for Achondroplasia?
Achondroplasia is caused by a mutation of the fibroblast growth factor receptor 3 (FGFR3) gene.
