Micronutrients (trace elements)- required in much smaller amounts and play roles in enzyme function and maintaining protein structure. In the case of the ill health of an organism, AAS can be used to detect whether required trace elements are present in sufficient quantities in the organism and its environment. Which of the following is a trace element that is required by humans and other vertebrates, but not by other organisms such as bacteria or plants?A) calcium B) iodine C) sodium D) phosphorus Which of the following is a trace element that is required by humans and other vertebrates? As a matter of fact, many of these elements are present at concentrations much lower than this. If a trace element deficiency is observed, then it can be rectified by providing the organism with that particular nutrient. Virtually all organisms require the same elements in the same quantities. Iodine is related with plants and bacteria is in the form of antiseptic, to eliminate microorganisms, but is not linked to either metabolism. The common nutrients which are found to be required in all living things include carbon, nitrogen, sulfur, phosphorus, potassium, magnesium, calcium, oxygen, iron and additional trace elements. The dietary elements or essential trace elements are those that are required to perform vital metabolic activities in organisms. By using this site, you consent to the use of cookies. These minerals are called trace minerals. Chromium helps the body keep blood sugar levels normal. Answer: C . In the context of nutrition, a mineral is a chemical element required as an essential nutrient by organisms to perform functions necessary for life. Trace elements are chemicals that are required by organisms in very small quantities for proper physiological and biochemical functioning. Calcium, sodium, potassium, magnesium, and chloride ions, along with phosphorus and sulfur, are listed with macronutrients because they are required in large quantities compared to micronutrients, i.e., vitamins and other minerals, the latter often described as trace or ultratrace minerals. Nutritionally deficits of these elements are considered a public health problem. Trace elements are required by an organism but only in minute quantities. a. pest-... Color blindedness is a sex-linked trait. In plants, calcium is primarily responsible for plant structure and cell wall formation. E) trace element. B12, and must obtain this cobalt-containing vitamin in the diet Copper is a trace element which can be found in almost every cell of the human organism. To be considered an essential element, three criteria must be satisfied: (1) the element must be demonstrated as essential to normal development and physiology in several species, (2) the element must not be replaceable in this role by another element, and (3) the beneficial function of the element must be through a direct physiological role, and not related to correction of a deficiency of some other element or indirect correction of a toxic condition. Such elements function as part of an amplification mechanism A process by which elements that are present in trace amouts can exert large effects on the health of an organism., in which a molecule containing a trace element is an essential part of a larger molecule that acts in turn to regulate the concentrations of other molecules, and so forth. trace element. 3. D) sodium . A) nitrogen B) calcium C) iodine D) sodium E) phosphorus. Ridgway, Roy Caring for your Unborn Child ( 1990 ) This latter is foolish because, as we have seen already , many of the trace elements compete with each other in the intestine . In biochemistry, an essential trace element is a dietary element that is needed in very minute quantities for the proper growth, development, and physiology of the organism. Skill: Knowledge/Comprehension Calcium, sodium, potassium, magnesium, and chloride ions, along with phosphorus and sulfur, are listed with macronutrients because they are required in large quantities compared to micronutrients, i.e., vitamins and other minerals, the latter often described as trace or ultratrace minerals. Many elements are required in trace amounts, usually because they play a catalytic role in enzymes. Answer: C . The physiological effect of any particular dose of a chemical is related to the specific susceptibility of an organism or species, as well as to environmental conditions that influence toxicity. Concept 2.2 An element’s properties depend on the structure of its atoms. Iodine can kill the bacteria. • C, H, and O 2. It is an inorganic mineral. A principle of toxicology is that all chemicals are potentially toxic. B) calcium . Evolution of tolerance to toxic materials Some elements can be toxic, for example, arsenic. and its Licensors The other essential elements are the trace elements, which are present in very small quantities. The other essential elements are the trace elements, which are present in very small quantities. These vary widely across species. Also referred to as microminerals, these trace elements are part of enzymes, hormones and cells in the body. A trace mineral or trace element is an element required in minute quantities by an organism to maintain physiological functioning. calcium, phosphorus, magnesium, sodium, potassium and chloride. E) phosphorus . Question sent to expert. Pest resistance2. n. (Biology) any of various chemical elements, such as iron, manganese, zinc, copper, and iodine, that occur in very small amounts in organisms and are essential for many physiological and biochemical processes. 2) Trace elements are those required by an organism in only minute quantities. trace element. This principle suggests that, although trace elements are essential micronutrients, which benefit organisms that are exposed within certain therapeutic ranges, at larger doses they may cause biological damages. D) sodium . Iodine salt and seafood are the major sources of iodine. Micronutrient requirements differ between organisms; for example, humans and other animals require numerous vitamins and dietary minerals, whereas plants require specific minerals.
