What are the differences between the classical and alternative pathways in the context of immune response activation?
The classical pathway is part of the innate immune response and is activated by specific molecules on pathogens. The alternative pathway is also part of the innate immune response but is activated by different molecules. Both pathways lead to the activation of the complement system, which helps to eliminate pathogens from the body.
What is the function of protein kinase in cellular signaling pathways?
Protein kinase is an enzyme that adds phosphate groups to proteins, which can activate or deactivate them in cellular signaling pathways. This process helps regulate various cellular functions, such as growth, metabolism, and communication between cells.

Are they three clotting pathways?
The coagulation cascade is classically divided into three pathways. The tissue factor (formerly known as the extrinsic) and the contact activation (formerly known as the intrinsic) pathways both activate the final common pathway of factor X, thrombin and fibrin.
What controls cell biochemical pathways?
Cell biochemical pathways are mainly controlled by enzymes, which are proteins that catalyze the chemical reactions involved in these pathways. Enzymes can be regulated through factors such as allosteric regulation, feedback inhibition, and post-translational modifications, which can either activate or inhibit their activity. Additionally, gene expression and signaling pathways can also play a role in controlling cellular biochemical pathways.

What stabilized c4bc2a complex?
C4bC2a is a C3 convertase, which is stabilized by the surface of the acvtivator (activating substance). It only will cleave C3, and can only be activated in one of three pathways: classical, lectin and alternative.
What activates the complement system?
The complement system can be activated through three main pathways: the classical pathway, the lectin pathway, and the alternative pathway. The classical pathway is initiated by the binding of antibodies to antigens, while the lectin pathway is triggered by the binding of lectins to specific carbohydrates on pathogens. The alternative pathway can be spontaneously activated on microbial surfaces in the absence of antibodies. Once activated, these pathways lead to a cascade of reactions that enhance immune responses, promote inflammation, and facilitate the destruction of pathogens.
What is complement activation?
Complement activation is a cascade of proteins in the immune system that helps to opsonize pathogens for phagocytosis, recruit inflammatory cells, and directly lyse target cells. It can be activated through three pathways: classical, lectin, and alternative pathways, and plays a critical role in innate immunity.

What is the role of the phosphoryl group in cellular signaling pathways?
The phosphoryl group in cellular signaling pathways acts as a key signal that can activate or deactivate proteins, regulating various cellular processes such as growth, metabolism, and communication between cells.
