Chemical and Physical Process of Digestion Essay

Introduction:- Human physiology studies the physical and biochemical processes that support the body 's function while anatomy studies the structures of the human body. Anatomy is divided into two parts which are histology: this is the atomic study of tissues and Cytology is the atomic study of cells. This unit focuses on both the anatomic feature this involves the morphology and forms of the part of the body and physiological features of the human body this involves the function of the part of

micronutrients. 1.1a Macronutrients Energy-supplying chemical substances from food are called macronutrients. They are usually taken (eaten) in large quantities. These are: carbohydrates, lipids, and proteins. 1.1b Micronutrients Just as macronutrients are essentials substances providing energy for the body, micronutrients are required for the prevention and treatment of various diseases and conditions, as well as the optimization of physical and mental functioning of the body. There are two types

Even Samuel Hahnemann, the father of homeopathic treatment, took up cudgels against the allopathic way of treatment where the worst thing, he claimed, was that one kind made another necessary. He was of the firm conviction that that allopathic treated a patient with medicines and formulae which, while curing one chronic illness, brought about another which was dissimilar to the one which had just been treated. He was a firm believer of nature’s cure which never planted another illness in the patient

CLASSES OF FOOD 1. Food is a basic necessity for all living things. 2. Food is important in order to : (a) Provide energy to carry out physical activities. (b) Provide energy for the physiological activities in life such as reproduction, digestion and excretion. (c) Build new cells and ti repair tissues in the body. (d) Protect the body from deseases. (e) Maintain the body temperature.

biodegradability of PHBs make them suitable materials to replace synthetic plastics in many applications. Currently their production is expensive, but these plastics are only in their first stage of commercial development. In the present study the physico-chemical parameters such as Time, Temperature and pH were optimized for increased production of PHB. It was found that maximum production of PHB was observed at 48th hour (328µg/ml) of incubation time, temperature 370C (336µg/ml), pH 7.5 (362 µg/ml). The

In recent years, the biotechnological use of xylans and xylanases has grown remarkably (Aristidou and Pentillä 2000; Subramaniyan and Prema 2002; Beg et al., 2001; Techapun et al., 2003). The end-products of xylan degradation of considerable importance in commercial applications are furfural and xylitol (Parajó et al., 1998). Xylan can be converted to β-D-xylopyranosyl and its oligosaccharides via two types of hydrolysis: acid or enzymatic. Acid hydrolysis is often preferred because it is faster

Adenosine triphosphate, ATP, is considered by biologists to be the energy currency of all life. ATP keeps us alive. It is a high-energy molecule that stores the energy we need to do just about everything. It is present in every cell. Physical mechanisms by the body that require energy mostly use ATP. ATP is remarkable for its ability to enter into many reactions. They both use food to extract energy and the reactions in other physiological processes provide energy to the cells by ATP. Our bodies

FOOD adulteration is the process of adding chemical substances with foods, which should not be contained within food and beverages. Chemical substances or simply adulterants may be internationally added to substances to reduce manufacturing costs, or for some deceptive or malicious purpose. When profit in business is more important than morality, then it is possible to add the poisoning contents to the foods and beverages. A limited number of people die without foods but large population have been

Metabolism is a process in which chemicals and enzymes break down food in the digestive system to make energy. The food is converted into simple sugars, energy and amino acids with the help of the mitochondria. A body can use this energy right away or it can store the energy in tissues such as liver, muscles, and body fats. A metabolic disorder happens when something goes wrong with the metabolic process because of abnormal chemical reactions. The metabolic disorder causes some substances to be produced

In the body, the chemical reaction going on in the body to keep the breathing, the heart beating and brain working all of these are derive the energy from. The three main macronutrients in living system which are fats, carbohydrates (sugar), lipids (fats), protein (amino acid). Moreover also needs some minerals and vitamins, they are usually required daily in large quantities nutrients. Metabolism refers to through various pathways of the physical and chemical processes that in the living
