Introduction Most vertebrates use aerobic metabolism for their energy needs. Although, some animals use anaerobic metabolism, in which food molecules are oxidized incompletely to lactic acid, lactate (Randall et al., 2002). There are particular times when animals cannot use aerobic metabolism for their energy needs. Such times include when oxygen is low in the environment. Also, when animals exercise, their increase in muscle contraction raises ATP demand resulting in the capacity for oxygen delivery

Nutrition is “the study of food and how it affects the human body and influences health.”1 Food affects the body and influences its health by providing it with nutrients. Nutrients which provide energy to the body are proteins, lipids, and carbohydrates. Micronutrients, vitamins and minerals, help to manufacture, repair, and maintain cells. Last but not least is water, which is considered an essential nutrient. When properly supplied; nutrients, micronutrients, and water the essential nutrient

Protein digestion Protein metabolism denotes the various biochemical processes responsible for the synthesis of proteins and amino acids, and the breakdown of proteins (and other large molecules, too) by catabolism.Dietary proteins are first broken down to individual amino acids by various enzymes and hydrochloric acid present in the gastro-intestinal tract.[1] These amino acids are further broken down to α-keto acids which can be recycled in the body for generation of energy, and production of

diet is based on the idea that controlling the level on insulin that will help you regulate the blood pressure, cholesterol, triglycerides, and fat storage in the. The protein power is a high protein, low-carbohydrate diet. This type of diet is mainly based on about 30 to 60 grams of carbohydrates and lots of lean proteins. This diet is very easy to follow and gives great fast result in no time, keeping your body lean. Protein serves primarily to promote growth and maintenance of the body tissue, it

to look at the features and nature of sugar. Sugar is a generalized name for a crystalline carbohydrate that is simple, edible and has a sweet flavor. The main types of sugar are sucrose, lactose, fructose and glucose. Glucose, also referred to as blood sugar is the one that circulates in the blood. Table sugar and fruits contain sucrose and fructose respectively. During the process of digestion, carbohydrates break down into glucose, which is the only form of sugar that the body absorbs. Sugars are

the relationship between eating and walking, and remember that Estrela is breathing. Metabolism is the effort of the body that is the breakdown of substances to form energy. One source of energy is glucose. When glucose is broken down, the body synthesizes glucose and then stores it to use it in the form of ATP (Adenosine triphosphate). Carbohydrates are another source of energy our body uses. Carbohydrates are similar to glucose in the way they are broken down and stored to be synthesized later

You need to make sure with the help of a dietician that how much carbohydrate is sufficient for you. Keep the amount of carbohydrate minimum but sufficient level which can fulfil your body requirements. When you eat more carbohydrates your body releases more as a result of which you urge to eat more. That is why it is imperative to decrease carbohydrate intake and increase protein rich food items. This will not only save you from hunger pangs but it will enable
