Answer:
3. Antibody-independent pathways of complement activation rely on complement components that directly bind to microbial surfaces.
Explanation:
There are three pathways of complement activation:
- The classical pathway.
- The alternative pathway.
- The lectin pathway.
The classical pathway is triggered by binding of C1 either to the pathogen surface or to antibody bound to the pathogen.
The alternative pathway is triggered by the spontaneous hydrolysis of soluble C3 to C3(H₂O) and initiates eventual deposition of C3 convertase on microbial surfaces.
The lectin pathway is triggered by the binding of mannose-binding lectin or ficolins to carbohydrate residues in microbial cell walls and capsules.
Quiet metabolism account for about 50% of the average person’s daily energy expenditures
A metabolism is a balancing act that involves two types of simultaneous activities: building up body tissues and energy stores (called anabolism) and breaking down body tissues and energy stores to get additional fuel for body functions (called catabolism)
Some of them are catabolic routes, such as glycolysis (the breaking of glucose), -oxidation (the breakdown of fatty acids), and amino acid catabolism. Others are anabolic pathways, such as those involved in energy storage (such as glycogenosis) and triglyceride synthesis (lipogenesis)
Metabolic pathways include the processes of producing and decomposing glucose molecules. A metabolic pathway is a chain of chemical reactions that feed off of one another.
