Biological Functions: processes and structures by which organisms adjust to short-term or long-term changes in their environment. (Brooker, 4) Biology rarely rests with a single solution. Instead, it tends to ceaselessly reinvent solutions Our bodies consist of a number of biological systems that carry out specific functions necessary for everyday living. The job of the circulatory system is to move blood, nutrients, oxygen, carbon.. BIOLOGICAL FUNCTIONS OF NUCLEOTIDES · Precursors of DNA and RNA. · Activated intermediates in many biosyntheses: e.g UDP-glucose ® glycogen, CDP-diacylglycerol ® phosphoglycerides, S-adenosylmathionine as methyl donor, etc. · Nucleotside triphosphates, especially ATP, as the universal currency of energy in biological systems This influences a range of important biological functions such as the process of endocytosis in which a cell wraps itself around a particle to allow its uptake. 1 The brain is very rich in fat (60%) and has a unique fatty acid composition; docosahexaenoic acid (DHA) is the major brain fatty acid Researchers have found that lipids have a much more diverse and widespread biological role in the body in terms of intracellular signalling or local hormonal regulation etc. Lipids are synthesized..

Sodium (Na) - 0.2% - Sodium is an important electrolyte. Like potassium, it is used for nerve signaling. Sodium is one of the electrolytes that helps regulate the amount of water in the body. Chlorine (Cl) - 0.2% - Chlorine is an important negatively-charged ion (anion) used to maintain fluid balance Regarding this, what is the biological function of lactose? Lactose is a type of sugar, naturally found in milk and dairy products. In the intestine, lactose is transformed by lactase, an enzyme, into glucose and galactose, both simpler sugars, which are used by our body for energy and various functions. Most people have difficulty digesting lactose Functions of carbohydrates in our body 4.1. Carbohydrates as energy source and their storage. Carbohydrates broken down to mainly glucose are the preferred... 4.2. The glycaemic response and glycaemic index. When we eat a carbohydrate-containing food, blood glucose level rises... 4.3. Gut function. NO has many important biological functions. It relaxes the walls of blood vessels, causing vasodilation (widening of the vessels). This allows more blood to flow into the heart and other organs. It also acts as a signaling molecule between nerve cells

The autonomic nervous system (ANS) refers to automatic functions of the body, e. g., heartbeat, blood pressure, intestinal secretions, and glandular secretions. The sense organs are vital to the communication of information to the nervous system. The five major senses are sight, hearing, taste, smell, and touch Vitamin E is the most effective, fat-soluble antioxidant known to occur in the human body. The main function of vitamin E is to maintain the integrity of the body's intracellular membrane by protecting its physical stability and providing a defense line against tissue damage caused by oxidation Changes in our body and environmental factors can cause our circadian rhythms and the natural light-dark cycle to be out of sync. For example: Mutations or changes in certain genes can affect our biological clocks. Jet lag or shift work causes changes in the light-dark cycle. Light from electronic devices at night can confuse our biological clocks All aspects of cell structure and functions are adapted to the physical and chemical properties of water. The following are the important biological significance or importance of water in the living system. (1). Water is a 'universal solvent'. (2). Water can dissolve most of the biologically important molecules. (3)

Biological Fuel Source The primary function of glucose is to serve as a biological fuel source for the body. All cells of the body are capable of using glucose to generate energy. Through a series of complex biochemical reactions, the breakdown of glucose yields high-energy molecules called adenosine triphosphate (ATP) Water Intake. Water leaves the body through several routes - the evaporation of sweat, in the moisture of exhaled breath, in the urine and in the faeces. It is also used to facilitate all the previously mentioned functions in the body. This amounts equals between 1.4-2.8 litres per day

They are energy production, energy storage, building macromolecules, sparing protein, and assisting in lipid metabolism DNA Biological Functions. In all living things, DNA is essential for inheritance, coding for proteins, and providing instructions for life and its processes. DNA dictates how a human or animal. Digestive system - anterior view. The human body is a biological machine made of body systems; groups of organs that work together to produce and sustain life. Sometimes we get lost while studying about cells and molecules and can't see the forest for the trees. It can be helpful to step back and look at the bigger anatomical picture Exogenous NO (NO-delivery drugs) Exogenous NO sources constitute a powerful way to supplement NO when the body cannot generate enough for normal biological functions. Certain endogenous compounds can act as NO-donors or elicit NO-like reactions in vivo.Nitroglycerin and amyl nitrite serve as vasodilators because they are converted to nitric oxide in the body When calcium levels in the body fall too low, the bones have to supply calcium to tissues and fluids so that normal biological functions can continue. As a result, calcium deficiency can cause the bones to weaken, raising the risk of fracture and increasing the risk of osteoporosis

Older cells function less well. Also, in some organs, cells die and are not replaced, so the number of cells decreases. The number of cells in the testes, ovaries, liver, and kidneys decreases markedly as the body ages. When the number of cells becomes too low, an organ cannot function normally. Thus, most organs function less well as people age The major function of hemoglobin is the transportation of oxygen from lungs to all the tissues of the body. The oxygen binding capacity of hemoglobin is 1.34 mL O 2 per gram. Each globin subunit of the hemoglobin molecule can bind with one Fe 2+ ion. The affinity of hemoglobin towards oxygen is gained by the Fe 2+ ion Peptides are biological molecules that are made up of amino acids. A peptide is a chain of covalently bonded amino acids that can consist of anywhere between 2 and about 40 amino acids in length, which can then be bonded together to form proteins in the body
