substrate which has the highest cellulose pellicle yield was using the ratio of CSL medium to coconut water at was 4:1(v/v). To the above medium‚ supplements consisted of sucrose (5%)‚ corn steep liquor (4%)‚ and ammonium acetate (3.75%). In fact‚ 7% sucrose gave the best yield; followed by 5% sucrose but the contribution of adding 7% sucrose is lower than that of 5%. The pH of medium was adjusted to initial pH 4.0‚ and incubated at 30℃ for 10 days; highest yield of cellulose pellicle was obtained. The cellulose

glucose‚ sucrose‚ and starch. It was hypothesized that glucose‚ sucrose‚ then starch would all be used to produce energy during fermentation. Being that glucose is a simple sugar‚ or monosaccharide‚ we predicted that glucose would be fermented most quickly. This hypothesis was made based on the idea that glucose is the cell ’s main source of energy in aerobic cellular respiration. The first step of cellular respiration is glycolysis which breaks down glucose for energy. We predicted that Sucrose would

Respiration is the process by which energy is released energy from glucose in the presence of Oxygen‚ forming carbon dioxide and water as waste products. Glucose releases energy in a series of reactions that take place inside components of the cell. The stages are briefly explained below as were briefly explained in part A‚ the process then goes through‚ glycolosis‚ link reaction and then the Krebs cycle. The volume of CO2 that is produced in the Krebs cycle is important as this is the dependant

concentration gradient. This is done to equalise the solute concentrations on the two sides. Therefore‚ in other words‚ the movement of water is depended on the concentration of dissolved solute in the water (in this case the sucrose) and if there are a higher concentration of sucrose in the visking tubing‚ the water in the beaker will move into the visking tubing to make both solution balanced (isotonic). In order for osmosis to occur naturally‚ a semi-permeable membrane is required as a medium. A visking

While mealy bugs pierce their stylets into sieve tubes and suck the sap‚ the white bugs have specialized in feeding on the sieve tube sap. Thus various studies
