recordID=175) Biodegradable plastics are degradable plastics on which the degradation results from the action of naturally occurring micro-organisms such as bacteria‚ fungi ‚ and algae (info@epi-global.com). These plastics are broken down into water‚ carbon dioxide‚ methane and biomass primarily through enzymatic action on microorganisms(Azios‚ 2007www.csmonitor.com/2007/1219/p16s01 -sten.html). Biodegradable will fully disintegrate in six months or less. It turns into powder and blends with the soil

Free Cellular respiration Adenosine triphosphate Photosynthesis
rate of photosynthesis is decreased by higher oxygen concentrations. Lower temperatures inhibit Rubisco and forces this enzyme to to work competitively. Rubisco works competitively because is actually binds itself to oxygen rather than binding to carbon dioxide because of the mere attraction. Therefore‚ in doing so‚ this activates photorespiration rather than photosynthesis. Photosynthesis in corn is different from photosynthesis in a tomato. Corn is part of CO4. CO4 plants are actually able to capture

Premium Metabolism Carbon dioxide Cellular respiration
means more material to produce carbohydrates‚ thereby‚ leading to the plants growing better. 6. Over the past decades‚ the CO2 concentration in the atmosphere has increased. Predict the effect of increasing carbon dioxide concentrations on photorespiration. The effect of increasing carbon dioxide concentrations on photorespiration would be that photorespiration rates should decrease as photorespiration involves rubisco reacting with O2 instead of CO2. Since CO2 is increasing‚ it would make it more

the cytosol via the phosphorylated intermediate‚ sucrose‐6′‐phosphate. In leaves‚ the rate of sucrose synthesis is tightly co‐ordinated with the rates of photosynthetic carbon dioxide fixation and starch synthesis in the chloroplasts. Sucrose is transported from leaves via the phloem‚ to provide the rest of the plant with carbon and energy for growth and storage product synthesis. Sucrose is also unloaded from the phloem in sink organs. It can be hydrolyzed by cell wall inverses and imported into
