The three pathways that activate the immune system's response are the alternative, classical, and lectin pathways. They work together to recognize and respond to foreign invaders, such as pathogens or damaged cells, in the body.
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.
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.
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.

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.

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.
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.

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.

C4 and CAM are two alternative photosynthesis pathways found in plants. C4 plants have a specialized mechanism to improve CO2 fixation in hot and dry conditions, while CAM plants use a temporal separation of carbon fixation during the night and day to conserve water.
