Photosynthesis Abstract: An experiment was carried out to determine how certain factors such as light intensity and availability of carbon dioxide‚ affected the rate of photosynthesis. The rate of photosynthesis was measure by the amount of oxygen produce (cm3/min). A valid conclusion was made and most of the results were in accordance with the prediction‚ although there were some anomalies present. The errors and limitations were evaluated and some improvements were suggested. Introduction: Photosynthesis

exists as a mixture of cyclic hemi-acetals (ring) and open-chain (acyclic) form within aqueous solution. The ring of D-glucose consists of 5 carbons and oxygen which each carbon is linked to a hydroxyl group with exception of the 5th carbon which is linked to a methyl-hydroxyl group. D-Glucose has 4 chiral centers when it is in ring form which the anomeric carbon appears at C1 which lead to the structure of α(axial‚ down) and β(equatorial‚ up) position 2. The ratio of this anomer exists within the aqueous

Enzymes and their importance in plants and animals (25 marks) Enzymes are biological catalysts‚ which accelerate the speed of chemical reactions in the body without being used up or changed in the process. Animals and plants contain enzymes which help break down fats‚ carbohydrates and proteins into smaller molecules the cells can use to get energy and carry out the processes that allow the plant or animal to survive. Without enzymes‚ most physiological processes would not take place. Hundreds of
