Theoretical Background Polymers of carbohydrates are called polysaccharides‚ and make up some of the most important naturally occurring compounds [1]. They have thousands of monosaccharide units linked to each other by oxygen bridges. They include starch‚ glycogen‚ and cellulose‚ all three of which yield only glucose when completely hydrolyzed [2]. A B Figure 1. Starch (amylose) (A) and cellulose (B) Starch occurs naturally in plants‚ which use it to storage glucose

The primary diagnosis of my patient is prematurity‚ she was born at 36 weeks and is considered a late preterm infant. Late preterm infants are at an increased risk for early death and long- term health problems when compared with infants who are born full term (Alden‚ 2012‚ p. 780). Late preterm are also at greater risk for complications such as respiratory distress and are more likely to be hospitalized longer and require intensive care. In addition‚ preterm infants are at risk because their

necessary energy to maintain body functions both at rest and during various forms of physical activity (McArdle‚ p.5). Carbohydrates serve several important functions related to exercise performance. The energy derived from the breakdown of glucose and glycogen is ultimately used to power muscular contraction as well as other forms of biologic work (McArdle‚ p.11). The other type of foodstuff that serves as a main

Nitrogen in the air enters and leaves living systems by way of the nitrogen cycle. Describe the events which take place when atmospheric nitrogen molecules move along a food chain (involving legumes and herbivorous mammals) and eventually return to the atmosphere. In your answer‚ describe the uptake‚ processing and utilization of nitrogen in the bodies of these organisms Atmospheric nitrogen in air enters by diffusion or gaseous exchange and leaves the bodies of most organisms without biotransformation

The amount of myoglobin within skeletal muscle increases‚ which allows more Oxygen to be stored within the muscle‚ and transported to the mitochondria. Muscles are a store of glycogen for energy. Enzymes involved in energy production become more concentrated and efficient

The Alimentary Canal The alimentary canal is a tube that extends from the mouth to the anus‚ about thirty feet in length‚ and lined throughout by mucous membrane. The alimentary canal walls have four basic layers or tunics. These are the mucosa‚ the submucosa‚ the muscularis externa‚ and either a serosa or adventitia. Each of these layers has a predominant tissue type and a specific function in the digestive process. The mucosa is the wet epithelial membrane abutting the alimentary canal lumen
