How do complement proteins cause foreign cell lysis?
Complement proteins cause foreign cell lysis through a process known as the complement cascade, which is initiated when these proteins are activated in response to pathogens. Once activated, they form a membrane attack complex (MAC) that inserts itself into the foreign cell's membrane, creating pores. These pores disrupt the osmotic balance of the cell, leading to an influx of water and ultimately resulting in cell swelling and lysis. This mechanism helps eliminate pathogens from the body effectively.
How zymogens are activated?
Zymogens are activated through proteolytic cleavage by specific enzymes, converting them into their active form. This activation step usually occurs in response to specific signals or conditions in the body. Once activated, the zymogen can perform its intended biological function.
What does it mean for a virus to have a lysogenic reproductive cycle?
The lysogenic cycle replicates the phage genome without destroying the host. Similar to Lytic reproduction, Lysogenic also begins when the phage inserts its DNA or RNA into the host cell through its surface. Once the nucleic acid is inside the cell, it forms a circle, and becomes a part of the genome of the host cell. It does this through genetic recombination, or crossing over. Once it joins the host’s genome, it is called a prophage. Since it is a part of the host cell’s genome, the phage’s genetic information is copied and distributed to the daughter cells of the host cell, which continues dividing naturally. This allows the prophage to be repeatedly copied and passed on without destroying the host cell it depends on for metabolic and reproduction purposes. In order for actual active phages to be produced, the segment of genome from the original phage exits the genome of the host cell and becomes independent. When this occurs, it begins the lytic cycle, destroying the cell, but producing new and functional phages.
Who manages the cct operation once the teams are activated?
The Incident Commander typically manages the Critical Care Transport (CCT) operation once the teams are activated. They are responsible for overseeing the overall operation, including coordination of team members, communication with stakeholders, decision-making, and ensuring the safe and effective transport of patients.
How are chemically gated channels activated?
Chemically-gated ion channels are receptor membrane proteins that are permeable to specific ions. The 'gating' part of it refers to the channel being open only once activated; which in this case will be by a chemical. An example would be the AMPA glutamate receptor, which has a channel pore that is permeable to sodium ions. Only by binding to glutamate (a neurotransmitter) does the channel allow sodium ions to enter the cell.
Can you return a Moshi Monsters Time Card?
No. Once the card has been paid for it is activated. Once the card is activated, it can not be returned.
Do you have to activated and how it you can?
When one really has activated, and even as decided once to use even go, it is then that he really has been can activated.
What causes nematocyst to discharge?
Nematocyst discharge is triggered by an immediate approach or a foreign stimulus. When the cell is discharged, a brand new nematocyst is created as the system in each cell can only be activated once.
What causes a nematocyst to discharge?
Nematocyst discharge is triggered by an immediate approach or a foreign stimulus. When the cell is discharged, a brand new nematocyst is created as the system in each cell can only be activated once.
Is tramadol300mg like heroin and what happends when someone chews 600mg at once?
no.
What the difference between a b cell and a b memory cell?
A plasma B cell is a B cell that has been activated to proliferate and produce antibodies against a specific antigen. A memory B cell is a B cell that lives a long time after an infection to provide long lasting immunity against that specific antigen. They both originate from the same B cell in your secondary lymph system. Once activated the specific B cell will proliferate into plasma B cells and memory B cells.
What causes the activation of a second messenger?
A transmitter activates a receptor on the cells surface. That receptor, once activated then activates the second messanger inside the cell. That way large molecules can provoke an effect within a cell without actually entering it.

Is yeast living nonliving?
Once yeast is activated it is living.
Where do undifferentiated lymphocytes migrate to?
B lymphocytes develop in the bone marrow. They then chill out in the blood until they meet an antigen that they are encoded and they become activated. However they need to be checked by another immune cell before to present auto-antigen. Once activated they then go to the spleen.
What happends to Rosalie and Emmett in twilight- do they have children?
No because once you are in the vampire state your body stops where you changed into.
What is the least expensive Sprint cell phone I can buy?
There are many different choices to pick from. What I have found is that you can get a free cell phone from Sprint with a 2 year contract once your phone is activated they waive the fee and all free phones are on line specials only.
