Let’s start. • Nutrition is a study of the interactions occurring between you & food. • Nutrients – about 45 substances that provide energy‚ structure or regulation of body processes. • Essential nutrients- need them‚ but can’t make them or fast enough. • Macronutrients- need in large amounts (carbohydrates‚ fats/lipids‚ proteins – provide energy/calories) • Micronutrients – need in very small amounts (vitamins‚ minerals- no energy/calories) • Phytochemicals- another category in plant food-

that corn indeed causes harmful effects on human health and the environment. In the first place‚ the public egregiously consumes corn in form of high-fructose corn syrup which gives rise to obesity problems. This kind of corn sweeteners largely replaced natural sugar in soft drinks and processed food. In tremendous quantities‚ such diet of high-fructose corn syrup and refined carbohydrates leads to an augment of insulin secretion. It would result in a wearing down of the metabolic system by catabolism

If you exercise regularly or if you are an athlete in training‚ you are trying to make your muscles work better. You want to be stronger if you are a weightlifter‚ you want to be able to throw a blistering fast ball if you are a baseball pitcher or you want to be able to finish strong at the end of a 26-mile race if you are a marathon runner. Adequate nutrition is a key component of sports performance. The greater the demands for increased performance both in training and competition‚ the higher

Organic Chemistry/Biochemistry 1: Compounds Important to Life • Biologists classify compounds into organic compounds and inorganic compounds. Organic Compound: a compound that is derived from living things and contains carbon Inorganic Compound: a compound generally derived nonliving things • Water Water is an inorganic molecule with unique properties that make it one of the most important compounds for living things. In the water molecule (H2O)‚ the hydrogen and oxygen atoms bond

BIOFERTILIZER: The pathophysiology of the Tuberculin reaction is explained thus: M. Tuberculi are engulfed by macrophages after being identified as foreign‚ but due to a self- preserving mechanism peculiar to TB it is able to block the fusion of the phagosome within which it is existing with the lysosome which would destroy it. So it can continue existing and replicating within the immune cell designed to destroy it. After several weeks‚ the immune system somehow [ mechanism as yet unexplained]

THE CONTINUOUS BREWING OF BEER Beer is produced commercially by the controlled fermentation of wort‚ a liquid rich in sugars‚ nitrogenous compounds‚ sulphur compounds and trace elements extracted from malted barley. Fermentation is the process by which glucose is converted to ethanol and carbon dioxide and is expressed chemically as: C6H12O6 + 2PO43- + 2ADP → 2C2H5OH + 2CO2 + 2ATP Behind this simplified chemical reaction is a series of complex biochemical reactions. These reactions (known as the

What are the central ideas of Cells? • What are cells? – Cells are the smallest basic unit of living things. • What do they do? – Cells take in raw materials and making new substances. • Why do they do this? – In cells‚ organelles carry out activities to keep the organism alive. – E.g. synthesising proteins and fats‚ releasing energy from glucose. What are the central ideas of Movement of Substances? • What processes describe how substances move from one region to another? –

filled by the carbon dioxide for each smith fermentation tube was measured. After 30 minutes‚ tube 4 (glucose substrate) showed the fastest formation of carbon dioxide which was the effect of the rate of respiration in yeast‚ followed by tube 5 (fructose substrate) then by tube 3 (sucrose substrate) then tube 2 (lactose substrate) and lastly tube 1 (starch substrate) that had no CO2 formation. Among these substrates glucose is the simplest sugar while starch is the most complex‚ this validates that
