3 Phases of Carbon Cycle Phase 1: Carbon fixation The Calvin cycle incorporates each CO2 molecule by attaching it to a five-carbon sugar named ribulose biophosphate (abbreviated RuBP). The enzyme that catalyzes this step is RuBP carboxylase‚ or rubisco. The product of the reaction is a six carbon intermediate so unstable that it immediately splits in half to form two molecules of 3-phoshpyglycerate (for each CO2) Phase 2: Reduction Each molecule of 3-phsophoglycerate receives an additional

What my project is about: I will be comparing results from water testing I did at two different water bodies to prove that the catchment area has an influence over the water quality in the different water bodies. The first water body I tested was the small dam in the bokkie park situated in between residential areas and in the middle of a piece of land solely used for animals. The second water body I tested was the small dam across the road from the Trinity Church in Boksburg on Rondebult Road‚ which

may seem like a significant increase‚ from a country’s perspective the growth is mediocre. This growth in real GDP ranks Uruguay as 94th world-wide in GDP purchasing power parity. Uruguay’s economy is in an expansionary peak phase of the Business Cycle as evidenced by the fact that GDP (purchasing power parity) was $44.029 billion in 2009 due to the world-wide economic crisis as a result of the United States’ Great Recession.
