Function of recognition proteins?
they enable cells to communicate with one another. It is possible due to cellular adhesion molecules on the surface of the membrane. They also distinguish foreign cells from self cells.
Are proteins too large to diffuse in cells?
Proteins are keep the cell going. They have many jobs to do one of which give the cell the energy to do what the cell is program to do in the body. So no proteins are not to large to diffuse in cells
What moves cell organelles from one location to another inside a cell?
Motor proteins help move organelles throughout the cell. Proteins always give energy, both in the human body system and within microscopic cells.
Cell-surface proteins allow a cell to what with other cells?
They allow Cells to communicate with other Cells.
Why target cell respond to the hormone while others are uneffected?
Target cells respond to hormones because they have specific receptors for the hormone on their cell membrane or inside the cell. These receptors enable the hormone to bind and initiate a cellular response. Other cells that do not have the specific receptors for that hormone are unaffected because they cannot bind to the hormone or activate the necessary signaling pathways.
What determines what cell a hormone will effect?
The target receptor proteins of cells will cause them to affected by a specific protein. These cells are also called "target" cells. Hormones flow via the bloodstream throughout the entire body, but they only affect their specific "target" cells.
explain why hormones in the bloodstream are able only to affect target cells/organs and not other cells/organs?
Hormones in the bloodstream are able to affect target cells/organs and not other cells/organs because of selective permeability. This means that hormones are only able to pass through the cell membrane of certain cells and organs, and not through the cell membrane of other cells and organs. The cell membrane of the target cells and organs are specialized to allow the hormones to pass through, while the cell membrane of other cells and organs are not specialized and are therefore impermeable to the hormones. This is due to the presence of receptor proteins on the cell membrane of the target cells and organs. These receptor proteins can bind to the hormones and facilitate their entry into the cell. Since these receptor proteins are not present on the cell membrane of other cells and organs, the hormones are unable to bind to them and therefore unable to cross the cell membrane. In addition, hormones can be broken down by enzymes in the bloodstream, which means they can’t reach their target cells and organs if they are exposed to the enzymes. This further ensures that hormones only affect the target cells and organs, and not other cells and organs. In summary, hormones in the bloodstream are able to affect target cells and organs and not other cells and organs because of selective permeability and the presence of receptor proteins on the cell membrane of the target cells and organs. Other cells and organs do not have these specialized receptor proteins and therefore cannot be affected by the hormones.
What do the proteins in cell membrane do?
Many are active and passive transmember proteins for the passage of material into and out of the cell and some are markers on the cell surface that distinguish one bodies cells from another bodies cells.
