similar to the contents of the chloroplast stroma and like the chloroplast‚ the mitochondrion is a semi-autonomous organelles containing the machinery for the production of some of its own proteins. The main function of the mitochondrion is the oxidation of the pyruvate derived from glycolysis and related processes to produce the ATP required to perform cellular work.(Campbell 182-9) Pyruvate‚ or fatty acids from the breakdown of triglycerides or phospholipids‚ pass easily through pores in the outer

properties of bitumen. There are mainly two types of ageing that is short term and long term ageing. There are two basic mechanisms involved in binder ageing; these include an irreversible process like chemical changes of the bitumen‚ consisting of oxidation of bitumen molecules‚ and loss of volatile components which subsequently has an impact on the rheological properties of the binders. The reversible process is the second mechanism termed as physical hardening; this involves the reorganization of

hydroxyl group. The carboxyl functional group may be attached to an alkyl group or an aromatic group. Benzoic acid‚ is a colourless crystalline solid and a simple aromatic carboxylic acid. It is mainly consumed in the production of phenol by oxidation decarboxylation at 300-400. Oxidizing a primary alcohol can produce carboxylic acids. In this experiment‚ an aromatic carboxylic acids namely benzoic acid will be prepared by oxidizing benzyl alcohol‚ which is an aromatic alcohol with the formula

TEACHING ENGLISH VOCABULARY TO ELEMENTARY SCHOOL STUDENTS BY USING CROSSWORD PUZZLE RAHAJENG Abstract Teaching vocabulary is something challenging‚ especially if it is done to elementary school students. It is chalenging because elementary school students usually do not like to learn something in a serious way. They are still children that like to play. A serious way in teaching will just make them bored. It is why teaching vocabulary to elementary school students requires creativity of the
