24. Explain why ATP yield in aerobic cell respiration is so much higher than in anaerobic respiration. (Long answer question – think about knock-on effects of reduced O2). 8 marks<br />Link question:<br />Draw and annotate sketch graphs of the effects of the following variables on rate of respiration – temperature, CoA concentration, pH. <br />Sample exam questions: <br />Practice these in your own time. <br />Describe the role of Acetyl CoA in the metabolism of lipids.

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. <br />80962564198500Biochemists 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. <br />(a)(i)Using only the data in the above graph, outline the effect of increasing fructose 6-phosphate concentration on the activity of phosphofructokinase, at a low ATP concentration.<br />...............................................................................................................................<br />...............................................................................................................................<br />...............................................................................................................................<br />(2)<br />(ii)Explain how increases in fructose 6-phosphate concentration affect the activity of the enzyme.<br />...............................................................................................................................<br />........................................................................................................................<br />...............................................................................................................................<br />...............................................................................................................................<br />(2)<br />(b)(i)Outline the effect of increasing the ATP concentration on the activity of phosphofructokinase.<br />...............................................................................................................................<br />...............................................................................................................................<br />...............................................................................................................................<br />...............................................................................................................................<br />(2)<br />(ii)Suggest an advantage to living organisms of the effect of ATP on phosphofructokinase.<br />...............................................................................................................................<br />...............................................................................................................................<br />(1)<br />(Total 7 marks)<br />Works Cited BIBLIOGRAPHY 1.
