Adrenal gland In mammals‚ the adrenal glands (also known as suprarenal glands) are the triangular-shaped endocrine glands that sit on top of the kidneys. They are chiefly responsible for releasing hormones in conjunction with stress through the synthesis of corticosteroids and catecholamines‚ including cortisol and adrenaline (epinephrine)‚ respectively. Anatomy and function Anatomically‚ the adrenal glands are located in the retroperitoneum situated atop the kidneys‚ one on each side. They are

A Critical Review of Peters‚ JW & Williams‚ LD 2012‚ ‘The Origin of Life: Look Up and Look Down’‚ Astrobiology‚ vol. 12‚ no. 11‚ pp. 1087-1092. The origin of life has always been one of the most attractive features in philosophy and science. Moreover‚ it can examine our knowledge of biological‚ geological and chemical principles. This review aims to provide information about consideration of the origin of life. The study reveals that the origin of life can be accomplished in both approaches

removal of glucose from the bloodstream. Introduction: The blood glucose concentration in the blood is interceded by the human body via negative feedback mechanism to maintain homeostasis of the body. Free glucose can be produced from fat‚ gluconeogenesis from proteins and glycogenolysis in liver and glucose is stored as glycogen in the muscle tissues. The human body intends to maintain a stable glucose concentration

Flowering plants grow in a wide variety of habitats and environments. They can go from germination of a seed to a mature plant producing new seeds in as little as a month or as long as 150 years. Plants that complete their life cycle in a single season are called annuals; while biennials take two years; and perennials may take several to many years to go from germinated seed to producing new seeds. Fruits and Seeds The taste of a fruit depends on the combinations present in it. Normally

To live only 10 to 20 percent of a functioning liver is required‚ however‚ if the liver is removed from the body a person will die within 24 hour of the removal.( http://www.drhoffman.com/page.cfm/623) "New" glucose (gluconeogenesis)‚ cholesterol and triglycerides among other substrates are produced in the liver. Metabolism of these important substrates are altered when the liver becomes fatty and enlarged .This tell the reasoning’s for the impaired glucose and cholesterol

Biochemistry GRT1 Task 4: Metabolism Enzyme Induced Fit Model and Activation Energy Role of Enzymes: Enzymes are proteins that act as catalysts during a biochemical process. Catalysts are non-changing enzymes that can increase or decrease activation energy to accelerate or slow down a biochemical reaction without using additional energy. Enzymes break down molecules in our body faster than they would normally break down without enzymes. On the biochemical level‚ enzymes work at precise
