Apple juice 125412559309000Carrot juice INTRODUCTION Fermentation is a slow decomposition of complex organic compound into simpler compounds by the action of enzymes. Enzymes are complex organic compounds‚ generally proteins. Examples of fermentation are souring of milk curd‚ bread making

gas do we need to breathe in? ___________________________________ • Where is this gas produced? __________________________________________________ Gizmo Warm-up During photosynthesis‚ plants use the energy of light to produce glucose (C6H12O6) from carbon dioxide (CO2)‚ and water (H2O). Glucose is a simple sugar that plants use for energy and as a building block for larger molecules. A by-product of photosynthesis is oxygen. Plants use some of the oxygen they produce‚ but most of it

(fig: 1 ) As chloroplasts contain a green pigment called chlorophyll‚ which absorbs light energy needed to make photosynthesis happen. The equation for this reaction is: 6CO2 + 6H2O+ light energy ---> C6H12O6 + 6O2 Sugars created in photosynthesis can be later converted by the plant to starch for storage‚ or it can be combined with other sugar molecules to form specialized carbohydrates such as cellulose‚ or it can be combined with other nutrients such

ABSTRACT The hypothesis which states that the simpler the nature of substrate‚ the faster the rate of cellular respiration of yeast was tested using the smith fermentation tube method. The experiment used six smith fermentation tubes‚ distilled water and sugar substrates. It composed of six set-ups which used 15ml of 10% yeast suspension‚ 15 ml distilled water and 15 ml of their assigned sugar substrate namely: starch‚ lactose‚ sucrose glucose and fructose respectively. Set-up six was the
