The endocrine system The endocrine system is a collection of ductless glands which are positioned through the whole body. The endocrine glands pass their secretions of hormones directly into the blood stream so that they are always adjacent to blood vessels. Hormones are chemicals in the body produced and secreted in the body that regulate the function of a particular tissue or organ (Bing dictionary). These chemical messengers transfer information from one set of cells to another. Despite many

down into aldosterone‚ cortisol‚ and androgens.iv The cortisol is bound together with a protein and together they are called glucocorticoids.iv This has many important jobs in the body. Some of the jobs of the glucocorticoids are to stimulate gluconeogenesis‚ mobilizes fatty acids and amino acids‚ elevate red blood cells and platelets‚ decrease cellular glucose use‚ and to cause anti-inflammatory effects.iv Without cortisol the liver doesn’t store glycogen as well‚ there is an increase of insulin

Induced Fit Model (Hudon-Miller‚ Enzymes‚ 2013) Why Does Aldolase B Deficiency Lead to HFI? • Understanding what happens to Glucose and Fructose in the liver is the first step. • Glucose enters the liver cell and Glucokinase is in the cytoplasm and adds a Phosphate (Pi) to make G-6-P to keep the glucose in the liver cell‚ which then becomes G-1-P and can be

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

HORMONES Hormones are a class of regulatory biochemicals produced in all multicellular organisms by glands‚ and transported by the circulatory system to a distant target organ to coordinate its physiology and behavior. They serve as a major form of communication between different organs and tissues. Hormones regulate a variety of physiological and behavioral activities‚ including digestion‚ metabolism‚ respiration‚ tissue function‚ sensory perception‚ sleep‚excretion‚ lactation‚ stress‚ growth and

The most common type of deaf-blindness disease in the world is Usher Syndrome. Usher Syndrome is a clinically and genetically heterogeneous disease. It is inherited in an autosomal recessive inheritance pattern. Worldwide‚ the chance of a baby being born with Ushers Syndrome is approximately 1 in every 25‚000 babies. To date‚ there are roughly 50‚000 people with Ushers Syndrome living in the United States. As stated above‚ Ushers Syndrome is an inherited disease characterized by hearing impairment
