Sample data analysis question (from IB QuestionBank)
At the start of glycolysis, glucose is phosphorylated to produce glucose 6-phosphate, which is converted into fructose 6-phosphate. A second phosphorylation reaction is then carried out, in which fructose 6-phosphate is converted into fructose 1,6-bisphosphate. This reaction is catalyzed by the enzyme phosphofructokinase.
Biochemists measured the enzyme activity of phosphofructokinase (the rate at which it catalyzed the reaction) at different concentrations of fructose 6-phosphate. The enzyme activity was measured with a low concentration of ATP and a high concentration of ATP in the reaction mixture. The graph below shows the results.

5.2 The Greenhouse Effect
The light dependent reactions of photosynthesis ‘fix’ CO2 from the atmosphere into organic molecules which are used for respiration in plants and animals. Respiration and combustion return CO2 to the atmosphere, whereas decomposition returns carbon to the atmosphere as methane.
Note: the enhanced greenhouse effect is NOT the same as the hole in the ozone layer. Read ahead to G3 Impacts of Humans on Ecosystems to see the distinction.
