Mitochondria are the cell’s power producers. They convert energy into forms that are usable by the cell. Located in the cytoplasm‚ they are the sites of cellular respiration which ultimately generates fuel for the cell’s activities. Mitochondria are also involved in other cell processes such as cell division and growth‚ as well as cell death. They convert oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy "currency" of the cell that powers the cell’s metabolic activities

Mechanism of melatonin stimulation of growth hormone release via somatostatin inhibition Joseph Angelo Israel Peguit University of the Philippines in the Visayas Cebu College Natural Sciences and Mathematics Division Abstract Secretion of growth hormone is affected by two primary hormones: Growth hormone-releasing hormone and somatostatin. The former is the primary stimulant to promote growth hormone secretion while the latter is the primary inhibitor that prevents growth hormone secretion

OBJECTIVE: 1. To distinguish the bacteria abilities to metabolize various substrates and end products formed. 2. To observe the growth of different bacteria species in term of structures and its morphology based on different chemical substance applied. 3. To observe physiological and immunological properties utilized by different species of bacteria. INTRODUCTION: Bacteria biochemical testing can determine the types and numbers in terms of colony forming units of bacteria present in a

Digestion is the mechanical and chemical breaking down of food into smaller components that can be absorbed into a blood stream‚ for instance. Digestion is a form of catabolism: a break-down of larger food molecules to smaller ones. In mammals‚ food enters the mouth‚ being chewed by teeth‚ with chemical processing beginning with chemicals in the saliva from the salivary glands. This is called mastication. Then it travels

An estimated 1 to 3 million athletes in the United States alone have used anabolic steroids (Silver 2001 & John M 2004). Anabolic-androgenic steroids (AAS) are chemically modified analogs of testosterone. Male sexual characteristics and muscle anabolism is responsible by the endogenous hormone (John 2004). Steroids are a group of hormones which are produced by two sets of glands‚ the adrenal glands and the sex glands. Silver 2001 and John 2004 suggest that the physiologic action of anabolic steroids
