Which one of the following is not a trace element in the human body?
a. fluorine
b. nitrogen
c. zinc
d. manganese
e. iodine.
The human body contains about 2.6% nitrogen. That is way above the percent in the definition of trace elements See:

Let's say a man cuts off a finger accidentally. Based on your knowledge of cells and their membranes what would you do to save it?
manganese
zinc
what is a trace element?
A trace element is an element that is present in very small amounts in the body. Trace elements are essential for normal body functions, such as growth, development, and metabolism. Examples of trace elements include iron, zinc, copper, selenium, iodine, and manganese.
A trace element is a mineral or element that is needed in very small amounts by the human body for normal physiological functioning. These elements are essential for various biological processes and are often required as cofactors or components of enzymes and proteins. Some examples of trace elements include iron, zinc, copper, iodine, selenium, and manganese.
To determine which of the options is not a trace element in the human body, we can refer to reliable sources such as scientific literature or reputable websites that provide information on human nutrition. One such source is the National Institutes of Health (NIH) website or articles published in peer-reviewed scientific journals.
Based on the options given, we can examine each element individually:
a. Fluorine: Fluorine is considered a trace element in the human body and is primarily found in bones and teeth, where it helps with tooth enamel formation and bone strength.
b. Nitrogen: Nitrogen is an essential element for all living organisms, including humans. However, it is not typically considered a trace element because it makes up a significant proportion of human body composition, primarily in the form of proteins and nucleic acids.
c. Zinc: Zinc is an essential trace element that plays a crucial role in various biological processes, including enzyme function, immune system health, and DNA synthesis.
d. Manganese: Manganese is also an essential trace element involved in several physiological processes, such as bone development, carbohydrate metabolism, and antioxidant defense.
e. Iodine: Iodine is a trace element that plays a vital role in thyroid hormone production, which regulates metabolism and growth.
Based on this information, the correct answer to the question is b. Nitrogen, as it is not considered a trace element in the human body due to its abundance and critical role in various biological processes.
