The cytoplasmic membrane is a poor target for antibacterial medication because it has a similar structure to eukaryotic cell membranes, leading to potential toxic effects in human cells if targeted. Additionally, bacteria can develop resistance mechanisms that modify their membrane structure to prevent drug entry. This makes it challenging to develop medications that specifically target bacterial membranes without affecting human cells.

What are the two general modes of hormone action?
Lipid-soluble hormones are able to penetrate through the cell membrane and bind to receptors located inside the cell. Such hormones diffuse across the plasma membrane and target those receptor cells found within the cytoplasm. Lipid-soluble hormones target the cytoplasmic receptors which readily diffuse into the nucleus and act on the DNA, inhibiting and stimulating certain proteins. lipid-insoluble are unable to penetrate through the plasma membrane and function with their target cells in a much different and complex manner. Lipid-insoluble hormones must bind with cell-surface receptors which follow a different path involving a second messenger. The hormone's inability to penetrate the membrane requires a second messenger which translates the outer message and functions within the cell.
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.
Why are electrophoretically fractionated proteins transferred to a membrane for detection?
Proteins are transferred to a membrane for detection after electrophoretic separation in order to facilitate detection of specific proteins using antibodies. This technique, known as Western blotting, allows for the visualization and quantification of target proteins by binding specific antibodies to the transferred proteins on the membrane.
During endocytosis what happens to the pocket in the cell membrane when it breaks loose from the membrane?
When the pocket in the cell membrane breaks loose during endocytosis, it forms a budding vesicle that encloses the material being internalized. This vesicle then pinches off from the membrane and moves into the cytoplasm of the cell to deliver the material to its target destination.
How do you isolate a membrane protein in the lab?
Membrane proteins can be isolated in the lab using techniques such as differential centrifugation, membrane fractionation, or immunoprecipitation. These methods involve disrupting the cell membrane to release the proteins, separating the membrane proteins from other cellular components, and purifying the target membrane protein using specific antibodies or tags.
Where can I buy some antibacterial soap?
Companies like Amazon and Target sell antibacterial soap online and in their local stores. They are sold at a very reasonable price and they can be delivered at any desired location. These antibacterial soap are in excellent condition and ready to use.
Only those who have the proper on the cell membrane are activated by the chemical messengers?
Target Cell
How are perforins different from granzymes?
Perforins are proteins that form pores in the target cell membrane, allowing entry of granzymes into the target cell. Granzymes are enzymes that are delivered into the target cell by perforins and trigger apoptosis, or cell death, in the target cell.
How does a hormone identify its target?
Only target cells have receptors inside cytoplazm (for steroid hormones) or on cell membrane (for protein hormones) that make the hormone active.
Are there stylish hypoallergenic brands of bed sheets for children?
Target has bamboo sheets that are really soft. Bamboo is great because it is naturally antibacterial so it should help with allergies.
Which cell contains membrane proteins en- abling a hormone to selectively bind to its plasma membrane?
The cell membrane contains the membrane proteins that enable a hormone to selectively bind to its plasma membrane. These proteins, such as receptor proteins, are responsible for recognizing and binding to specific hormones, allowing the hormone to exert its effects on the cell.
What structure is involved in phagocytosis?
Plasma Membrane !

Where can you buy Lice-X?
Your local pharmacy or drugstore should contain the medication. If not, try your nearest Walmart Supermarket or Target.
A cell that contains proteins enabling a hormone to selectively bind to its plasma membrane is called what?
A receptor cell.
Cytotoxic t cells destroy their target cells by releasing substances that alter?
Cytotoxic T cells release substances like perforin and granzymes, which create pores in the target cell membrane leading to cell death. These substances trigger a cascade of events inside the target cell, ultimately causing its destruction. This is a crucial mechanism for eliminating infected or abnormal cells in the body.
Hormones attach to plasma membrane proteins called?
Hormones attach to plasma membrane proteins called receptors. These receptors can trigger signaling pathways within the cell when activated by the hormone binding.
