The group of proteins that normally circulate in the blood in an inactive form and are activated by contact with nonspecific antigens such as foreign blood cells or bacteria?

These proteins are part of the complement system, which forms a crucial part of the immune response. Once activated, the complement proteins can lead to the destruction of pathogens through processes such as opsonization, inflammation, and cell lysis.


What does the outer membrane do?

It is made of phospholipids just as the cell membrane is. There are some differences in the type of proteins embedded in each membrane. Mitochondria have their own DNA and are thought to be another organism that became taken up by a larger cell. Both have benefitted by the relationship.


Why is the cell membrane vital to the cell?

The cell membrane is vital to the cell because it acts as a barrier, controlling what enters and exits the cell. It also helps maintain cell shape and structure. Additionally, the cell membrane contains receptors that allow cells to communicate with each other and with the external environment.


Explain the role of membrane carbohydrates in cell-cell recognition?

membrane carbohydrates are used for the selection of cells to make tissues, and the rejection of foreign cells (like in your blood). Cells recognize each other by binding to surface molecules, often carbohydrates, on the plasma membrane. Membrane carbohydrates may be covalently bonded to lipids of more commonly proteins (forming glycoproteins). Carbohydrates on the external side of the plasma membrane vary among species, individuals, and even cell types in an individual


What are the differences between electroporation and heat shock methods for introducing foreign DNA into cells?

Electroporation and heat shock are two methods used to introduce foreign DNA into cells. Electroporation involves applying an electric field to create temporary pores in the cell membrane, allowing the DNA to enter the cell. Heat shock, on the other hand, involves briefly exposing the cells to high temperatures, which causes the cell membrane to become more permeable, allowing the DNA to enter. In summary, electroporation uses an electric field to create pores in the cell membrane, while heat shock uses high temperatures to make the membrane more permeable.

How does complement kill foreign microbes?

Complement is a part of the immune system that can kill foreign microbes by either directly lysing them through the formation of a membrane attack complex or by marking them for phagocytosis by immune cells. It can also enhance the inflammatory response against the microbes, aiding in their clearance from the body.

What group of proteins mark foreign invaders and attract phagocytes to destroy them?

B cells release antibodies that attach to foreign invaders and mark them for destruction by phagocytes.


What controls movement into and out of the nucleus?

The cell membrane controls the movement into and out of the nucleus. The cell membrane is a barrier that keeps cellular materials in and foreign objects out.


What is The binding of complement proteins to certain sugars or proteins on a foreign Cell's surface?

Opsonization is the process where complement proteins bind to sugars or proteins on a foreign cell's surface, which marks the cell for destruction by phagocytic cells like macrophages and neutrophils. This process enhances the immune response against the foreign cell, helping to eliminate it from the body.


If complement and SRBC added and hemolysis occur how you will interpretate?

If complement and SRBC are added and hemolysis occurs, it indicates that the complement system is functioning properly. The lysis of the SRBCs suggests that the complement system has been activated in response to the foreign cells, resulting in their destruction. This can be used as an assay to assess the activity of the complement system.


What does a cherry symbolize?

The hymen. Its a membrane in the vagina that breaks when penetrated by a foreign object.
