Quiet metabolic activities account for about ________ of the average person’s daily energy expenditures
Valentin [98]

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.

Ugo [173]

Answer:

IgE

Explanation:

Immunoglobulins can be described as antibodies that are found in blood and other bodily fluids of humans and other vertebrate animals. And their major function is that they help identify and destroy foreign substances such as microbes such as bacteria and protozoan parasites.

They are known to be produced by produced by plasma cells (white blood cells).

Immunoglobulins are classified into five categories: IgA, IgD, IgE, IgG and IgM. And are distinguished by the type of heavy chain they contain. IgG molecules possess heavy chains known as γ-chains; IgMs have μ-chains; IgAs have α-chains; IgEs have ε-chains; and IgDs have δ-chains.

In this case, IgE is the immunoglobulin that attach to and sensitize mast cells and basophils.
