What are the most abundant elements in the body

Biology
1 answer:
V125BC [204]4 years ago
3 0

Answer:

Oxygen

Carbon

Hydrogen

Explanation:

<h3>Oxygen  :</h3>

Oxygen is the most abundant element in the human body. It makes up 65 percent of the total weight of a person. For a person with a weight of 155, about 94 pounds of her total weight would be made of the element oxygen. This is due mainly to the body's water content. Water makes up the majority of the human body, and the two elements that make up water are oxygen and hydrogen. Oxygen is also present in both our inhalations and exhalations. When breath in air from the surrounding atmosphere, some of it is oxygen. When we exhale, we breathe out the molecule carbon dioxide, which is made of the elements carbon and oxygen.

<h3>Carbon  :</h3>

Carbon is the second most abundant element in the human body, and makes up about 18 percent of your total weight. For a person weighing 170, 35 pounds of that weight is from the element carbon. Carbon forms the backbone of DNA, which present in most of the cells present in the human body. Carbon is also present in the sugar molecules your body uses for energy. We consume carbon from the food we eat, and release it back into the environment when we exhale.

<h3>Hydrogen  :</h3>

Hydrogen is the most abundant element in the universe, and is also the smallest element. It makes up about 9 percent of the total weight of the human body. A person who weighs 170 pounds gets about 15 pounds of that weight from hydrogen. Two hydrogen atoms are present in every water molecule. Hydrogen is found in many other biological molecules in the human body. The present of hydrogen atoms on a fatty acid molecule determines if the fat is saturated or not.

<h3>Other Abundant Elements  :</h3>

Beyond these three elements, the next three elements that occur in greatest abundance in the human body are nitrogen, calcium and phosphorous. Together, these elements make up about six percent of the total weight of the human body. Nitrogen is found in the proteins, while calcium and phosphorous have their greatest concentrations in your bones and teeth. Phosphorous is also present in the DNA chain and is an essential component to the membranes enclosing your cells.

How might you model the relationship between a tomato plant and the hornworm caterpillar?
AlexFokin [52]

Answer:

This model can be called a parasitic relationship

Explanation:

A <em>parasitic relationship is a form of relationship/interaction between two organisms in which one organism (called parasite) lives at the expense of the other organism (called host); causing harm or death to the host</em>.

A hornworm caterpillar feeds on the upper part of tomato plant leaves, causing harm to the plant in the process. Hence, <u>the tomato plant is the host while the hornworm caterpillar is the parasite.</u>

How is the circulatory system of the earthworm different from the crayfish? hypothesize as to why these differences exist (hint
dem82 [27]

Answer:

The circulatory system of the crayfish is an open system where the blood is contained in vessels for only part of the system. The heart is located in a pericardial sinus located in the upper part of the thorax (a sinus is a sac or cavity). The heart pumps the blood into the arteries.

During glycolysis, a 6-carbon sugar diphosphate molecule is split into two 3-carbon sugar phosphate molecules. True or false?.
Hatshy [7]

The above statement is true. During glycolysis, a 6-carbon sugar diphosphate that is fructose-1,6-bisphosphate is splitted into two 3 carbon sugar phosphate molecules that are dihydroxyacetone phosphate and glyceraldehyde-3-phosphate.

<h2>What is glycolysis? </h2>

Glycolysis is a 10-step reaction wherein glucose is divided into two pyruvate molecules, each of which has three carbons.

Glycolysis is the initial step in the process of cellular respiration in organisms. However, many anaerobic organisms also contain this route since glycolysis does not require oxygen.

<h2>What are the various steps involved in glycolysis? </h2>

1. The conversion of D-glucose into glucose-6-phosphate is the initial step in the glycolysis process. The enzyme catalyst in this case is hexokinase.

2.This second phase involves the conversion of fructose 6-phosphate  from glucose 6-phosphate.

3. Using magnesium as a cofactor, fructose 6-phosphate is changed into fructose 1,6-bisphosphate.

4. Fructose 1, 6-bisphosphate is split into two identical sugars by the enzyme aldolase. Dihydroxyacetone phosphate (DHAP) and glyceraldehyde 3-phosphate are the names of these two sugars.

5.The molecules glyceraldehyde 3-phosphate and dihydroxyacetone phosphate (DHAP) are quickly interconverted by the enzyme triphosphate isomerase.

The first five steps listed above are regarded as the initial phase.

6.Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) converts glyceraldehyde 3-phosphate into 1,3-bisphosphoglycerate by dehydrating it and adding an inorganic phosphate.

7. To create ATP and 3-phosphoglycerate, a phosphate group from 1,3-bisphosphoglycerate is transferred to ADP.

8. In this step, Phosphorous from 3-phosphoglycerate is transferred from the third carbon to the second carbon to generate 2-phosphoglycerate.

9. An enzyme removes a water molecule from 2-phosphoglycerate to create phosphoenolpyruvic acid (PEP).

10. Phosphoenol pyruvic acid is converted to pyruvate.

What’s the difference between field farm and factory farm
marusya05 [52]

Answer: Industrialized agriculture is highly concentrated and mechanized, relying on chemical inputs like fertilizers, pesticides and non-therapeutic antibiotics. However, sustainable agriculture, which uses methods that protect the environment, public health, human communities and animal welfare, is gaining traction.
