The Great Metabolic Race Organisms are constantly undergoing various chemical reactions and pathways that enable for them to maintain life. These pathways are part of metabolism‚ involving catabolism (break down of organic nutrients for extraction of useful) and anabolism (energy dependent conversion of small precursor molecules in complex molecules); some of which are energy coupled to provide energy efficiency. This intermediate coupling is due to the “energy currency” within the body‚ known as

INTROduction TO THE HUMAN BODY 1. Define anatomy and physiology While anatomy provides us with a static image of the body architecture‚ physiology reveals the body’s dynamic and animated workings. Physiology often focuses on events at the cellular or molecular level. A. Anatomy – studies the structure of the body parts and their relationship to one another. i. Developmental – concerns structural changes that in the body occur throughout the lifespan. Embryology studies the developmental changes

maintain the blood glucose at optimum level. When there is a rise of glucose in the blood especially after meals‚ insulin works to convert glucose into glycogen by glycogenesis as well as into lipid by lipogenesis. However‚ in people with type 1 diabetes‚ their body are not able to supply sufficient insulin for converting the glucose into glycogen as the storage

Health Center‚ the organic molecules included are carbohydrates‚ proteins‚ and lipids. Carbohydrates in particular are the essential fuel source for the human body’s mechanisms. They are stored in the tissues and cells of the body as glucose and as glycogen‚ the carbohydrate used for muscle movement‚ as well as in the liver‚ until the stored energy is used later (Volesky). The energy mobilized from carbohydrates is stored in the bonds between its monomers. A monomer is the repeating‚ basic unit found

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
