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]

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

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-

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

Covered in chemicals‚ inedible until processed‚ the production of high fructose corn syrup‚ the loss of small family farms‚ it’s damage to the environment‚ and its use as cattle feed are a few of the reasons this new era of corn needs to be changed.
