False. Presynaptic cells release only one type of neurotransmitter while the post synaptic cell can sense multiple types of neurotransmitters.
Presynaptic cells are responsible for releasing neurotransmitters into the synaptic cleft, which is the space between the presynaptic cell and the post synaptic cell. Each presynaptic cell releases only one type of neurotransmitter, but the post synaptic cell has the ability to sense multiple types of neurotransmitters through the presence of various receptors on its surface. These receptors are responsible for binding with the neurotransmitters and transmitting the signal to the post synaptic cell. Therefore, it is false that each presynaptic cell can release different types of neurotransmitter while the post synaptic cell can only sense 1 type.

What are the mechanism(s) of membrane attack complex
formation in the classical and alternative ways of complement
activation?
The classical pathway of complement activation involves the recognition of specific pathogen-associated molecules (PAMPs) by antibodies that are bound to the membrane of a target cell.
The membrane attack complex (MAC) is formed via either of the two ways of complement activation: classical and alternative. The mechanism of MAC formation in the classical and alternative ways of complement activation is mentioned below:
Mechanism of MAC formation in classical complement activation: In classical complement activation, C1 complex is formed in response to the presence of antigen-antibody complexes or modified surfaces. C1 complex consists of C1q, C1r, and C1s proteins. C1q binds to the Fc region of the antibody, while C1r and C1s cleave and activate C4 and C2. C4b and C2a together form C3 convertase.
C3 convertase cleaves C3 into C3a and C3b. C3b binds to the surface of pathogens, and it, along with C4b and C2a, form the C5 convertase. C5 convertase cleaves C5 into C5a and C5b. C5b binds to the surface of pathogens, and it initiates the assembly of the MAC on the membrane. C6, C7, C8, and C9 are recruited to the site of C5b, and they together form the MAC.
Mechanism of MAC formation in alternative complement activation: In alternative complement activation, C3 convertase is formed via the spontaneous hydrolysis of C3.
The C3 convertase consists of C3b and Bb. Properdin (P) binds to the C3 convertase, and it stabilizes the convertase. The C3 convertase cleaves more C3 to C3a and C3b. C3b binds to the surface of pathogens and forms the C5 convertase with C3b, Bb, and C3b. Further, the formation of the MAC occurs similarly as in classical complement activation.

You would expect to find an activated, ligand-bound steroid hormone receptor in the nucleus of the cell, specifically bound to HREs within the DNA to regulate gene expression.
An activated, ligand-bound steroid hormone receptor is a type of nuclear receptor that functions as a transcription factor, regulating gene expression in response to the binding of a hormone. These receptors are typically found in the cytoplasm of cells when they are inactive, bound to chaperone proteins that prevent their entry into the nucleus.
Upon binding to a hormone, the receptor undergoes a conformational change that causes it to dissociate from its chaperones and translocate into the nucleus, where it can bind to specific DNA sequences called hormone response elements (HREs). This binding triggers a cascade of events that ultimately leads to the activation or repression of target genes.

Upon assessment, she has a heart rate of 105 beats per minute and a blood pressure of 96/53 mm Hg. Auscultation of her lungs reveals high pitched wheezing. Her husband said she has reacted to bee stings in the past.
1. Ms. Stinger is experiencing a _________________ hypersensitivity response: (circle one) (.5 pt) Type I Type II Type III Type IV
2. Describe the type of hypersensitivity response Ms. Stinger is experiencing. (In other words, how does this type of hypersensitivity work) (1.5 pts.)

5. Why is she wheezing? (1 pt.)
6. What treatment can she be given to reduce her signs and symptoms and how does it work? (1 pt.) Make sure to answer both parts of the question for full credit.
According to the situation given in question Ms. IRMA Stinger is experiencing a Type I hypersensitivity response. Answer for the following questions are as follows:
1. Ms. Stinger is experiencing a Type I hypersensitivity response.
2. Type I hypersensitivity response is an immediate allergic reaction that occurs when an allergen, in this case the hornet venom, triggers the release of histamine from mast cells. Histamine is a chemical mediator that causes the symptoms of an allergic reaction, such as itching, swelling, and inflammation. In severe cases, like Ms. Stinger's, the reaction can cause anaphylaxis, which is a life-threatening condition that requires immediate medical attention.
3. Ms. Stinger is experiencing tachycardia, or an increased heart rate, because her body is trying to compensate for the drop in blood pressure caused by the allergic reaction. The heart is working harder to pump blood to the organs and tissues in an attempt to maintain adequate blood flow and oxygenation.
4. Ms. Stinger's blood pressure is low because the release of histamine causes the blood vessels to dilate, which reduces the resistance to blood flow and lowers blood pressure. This can lead to a decrease in blood flow to the organs and tissues, which can be life-threatening if not treated promptly.
5. Ms. Stinger is wheezing because the release of histamine causes the smooth muscles in the airways to constrict, which narrows the airways and makes it difficult to breathe. This is known as bronchoconstriction and is a common symptom of an allergic reaction.
6. Ms. Stinger can be given epinephrine, which is a medication that counteracts the effects of histamine. Epinephrine constricts the blood vessels, which increases blood pressure and improves blood flow to the organs and tissues. It also relaxes the smooth muscles in the airways, which helps to relieve the wheezing and difficulty breathing. In addition, she can be given antihistamines, which block the action of histamine and help to reduce the symptoms of the allergic reaction.
