Energy Balance

ntroduction

As everybody is aware that power comes from foods such as CHO, alter and protein, as well as, nil is required in most(prenominal) of body functions and to maintain the growth and development. Energy balance tail be classified as positive and negative energy balance. The positive energy balance food such as ethanol is able to yield more energy than it takes darn the negative is in the opposite. Energy balance can be also summarized as:
Energy input = Energy sidetrack
There are 3 components related in the cadence about the energy expenditure, basal metabolic rate, physiologic employment and the thermic effect of food. They are all influencing energy product with affecting factors day to day. Energy imbalance might topic obesity and under-nutrition (National Institutes of Health, 2002) that depends on the amount of energy stores, which are in the public figure of glycogen and triacylglycerides. Hence, healthy diet and normal physical activities are important for energy balance.

3.Pancreas secretes two types of hormones to regulate the blood glucose train. Insulin will be secreted when blood glucose level is high. It converts excess blood glucose to glycogen to humiliate blood glucose level. Glucagon is a hunger hormone and is secreted when blood glucose level is low. It plays a role to increase blood glucose level by converting glycogen to glucose in the liver.

4.Glycogen is a storage form of glucose. Liver synthesize approximate 100g of glucose per day. A glycogen scrap can be made of up to 120,000 glucose. Liver storage is gone in 24 hours. Glycogen content in liver is 742kcal in maximum and there is typically 300kcal stored in a...If you want to get a full essay, order it on our website: Ordercustompaper.com
