How do you prepare 5mM EDTA of 100ml solution?
5mM = 0.005 moles
100 mL = 0.1 Liters
Molarity = moles of solute/Liters of solution
0.005 M EDTA = X moles/0.1 Liters
= 0.0005 moles EDTA
=_____________ Now, look up the molecular formula for EDTA and find how many grams needed to add to your 100 mL.
What are the parts of an enzymes?
Active sites. Those atoms of the molecule that effect the London bonds to the target molecule.
Structure Those atmos that provide the 'scaffolding' that ensure that the active sites are exactly where they should be.
Which hormones exerts its effect primarily on the reproductive organs?
The hormone primarily affecting the reproductive organs is gonadotropin-releasing hormone (GnRH). GnRH regulates the secretion of other hormones such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn control the functions of the gonads (ovaries and testes) and their production of sex hormones like estrogen and testosterone.
What advantages does oxidative phosphorylation have over anaerobic glycolysis?
Both processes are run inside the human body in order to produce energy. Oxidative phosphorylation produces much more energy at a less of an expense than anaerobic glycolysis. It also has energy coming from multiple sources unlike anaerobic glycolysis which only comes from one source.
Which is the best vegetable for nutrition?
The best vegetable is the one you actually eat! :)
Vegetables contain vitamins, minerals, and even protein. You can find out which vegetables are highest in nutrients by looking at various canned vegetables and comparing ingredients listed on the labels.
But once you find the most nutritious canned vegetable, you should see if you can get that vegetable either fresh or frozen, because canned vegetables usually contain extra salt, and the heat required for processing can kill nutrients as well.
There are other ways to find the best vegetables. You can search "nutrients in vegetables" on Google or other search engines, and click on links that give you charts to compare foods.
You can also call your local hospital's dietary department and see if they have brochures on nutrition for the general public.
What female condition may require hormone replacement therapy?
Hormones effect the whole body. Hormones have an impact on the body's ability to cope with stress, fight disease, and metabolize calories. Though hormones typically bring to mind thought of reproduction and sex, hormonal imbalances in both men and women are implicated in a wide variety of symptoms that could be mistaken for other disease states and illnesses.
In men, hormonal imbalance can have a physical effect as well as effecting the mood. Depression, anxiety, and anger or irritability can all be symptoms of hormone imbalance, particularly if mood problems accompany other symptoms like difficulty urinating or a lower libido. Difficulty losing weight and unexplained weight gain or weight loss, reduced muscular strength, water retention, and bloating may also signify that there is a hormonal imbalance in the body. Headaches, trouble focusing, fatigue, and low blood sugar as well as allergies can all be brought on by hormonal imbalance in males. In males, restoring hormone balance can promote a heightened sense of well-being both physically and emotionally.
Women experience a different set of symptoms related to hormonal imbalance. Though hormonal imbalance has been primarily associated with menopause in women, it is also the cause of a lot of mood problems and symptoms of PMS. Women may experience difficulty sleeping, night sweats and hot flashes. Sex drive in women is also effected by hormonal imbalance. Women may also experience fatigue, foggy thinking, and insomnia. Endometriosis and fibrosis are health issues that are exacerbated and sometimes caused by hormonal imbalance.
Both men and women can benefit from natural hormone replacement therapy to restore balance to the body. Having balanced hormones can increase quality of life and slow the aging process.
Elisa (Enzyme-Linked Immunosorbent Assay) is a common laboratory technique used to detect the presence of antibodies or antigens in a sample. It is widely used in medical diagnostics, food testing, and research settings to identify and quantify specific molecules.
Why Knowledge of Nutrition Important?
Without learning you would be nowhere in later life. Before you are born you are learning and you learn all of your life. You learn to walk, talk, eat, and to do things. People who suffer brain damage have to relearn everything they once knew. Sometimes that doesn't happen or the brain can't repair itself and problems remain. Learning is vital to maintain life.
Learning can keep the body and mind in good condition.
Why do lipid produce more ATP than glucose even though they have same number of carbon?
Lipids don't have the same number of carbon atoms as glucose -- glucose has six while a lipid triglyceride can have a number exceeding 60 carbons. The reason it makes more ATP than glucose is because there are more chemical bonds to be broken as they are relatively large molecules.
Energy is stored in covalent bonds when they are formed, and is released when they are broken. The release of energy can be used to bind a phosphate (Pi) to a molecule of ADP (adenosine diphosphate, with two phosphate groups), creating ATP (adenosine triphosphate, with three phosphates). The greater number of bonds in the molecule, the greater amount of energy released, so more ATP can be synthesized.
What impact has nutrition on society?
To understand what nutrition does to us we must understand what nutrition is.Nutrition is defined as elements that are obtained from animal and plants product that are highly recommended for proper physiological growth of an individual. The main function of Nutrition, therefore is the proper growth of the body.The other important things it does in the body is, provides antigens ( once they are processed by the body) to maintain strong immune power, to obtain energy for day to day work, to be safe from diseases.
dNMP stands for deoxyribonucleoside monophosphate, which is a building block of DNA. It consists of a deoxyribose sugar, a nitrogenous base (adenine, guanine, cytosine, or thymine), and a single phosphate group. These molecules are essential for DNA replication and synthesis.
What are common items that would best represent the primary structure of a protein?
beads of different colors joined together on a piece of string
Name three substances obtained from common salt?
Three substances obtained from common salt are sodium chloride (table salt), bleach (sodium hypochlorite), and baking soda (sodium bicarbonate).
Do O level Food and Nutrition exams have practicals?
Yes, O level Food and Nutrition exams typically include practical assessments where students demonstrate their cooking skills, food preparation techniques, and knowledge of nutrition principles. Students are usually required to complete practical tasks such as preparing and presenting dishes in a controlled environment to showcase their understanding of the subject.
Bananas are a good source of vitamin B6 (pyridoxine), vitamin C, and contain small amounts of other B vitamins like thiamine and riboflavin. They are also a good source of dietary fiber and potassium.
What organic constituents are normally found in the blood?
Organic constituents commonly found in blood include glucose, amino acids, fatty acids, and hormones. These compounds play crucial roles in various physiological processes such as energy production, protein synthesis, and cell signaling.
Is gentiobiose reducing or non-reducing sugar?
yes it is a reducing sugar, it has a free anomeric OH group. thus it can also mutarotate
What vitamin you take from sun?
The main vitamin obtained from sun exposure is vitamin D. Our skin synthesizes vitamin D when exposed to sunlight, specifically UVB rays. This vitamin is essential for maintaining healthy bones, regulating immune function, and supporting overall well-being.
How many Of the 20 amino acids relevant to the human body are considered nonessential?
There are actually 20 amino acids... There are 11 non-essential and 9 essential.. The non essential amino acids can still be used to sythesized in the body from other amino acids or by adding nitrogen to carbon containing structures... : ).. Im in nutrition classes
What is the atom that is most closely associated with living things?
Carbon is the atom most closely associated with living things because it forms the backbone of organic compounds, including carbohydrates, fats, proteins, and nucleic acids, which are essential for life processes. Carbon's ability to form covalent bonds with other elements allows it to create a wide variety of complex molecules that are crucial for the functioning of living organisms.
The buildup of the products of nucleic acid metabolism can lead to?
The buildup of the products of nucleic acid metabolism can lead to issues such as gout, kidney stones, and potential toxicity due to the accumulation of purine metabolites like uric acid. This can disrupt normal cellular functions and lead to conditions associated with impaired nucleic acid metabolism.
What other plants can be used as alternatives for litmus paper?
