Question

For this question, consider the following information regarding ingredients in fruitjelly. Jellies are produced with fruits from plants that do not have PEPCase (e.g., strawberry, raspberry, etc.). Sweeteners are produced from plants with PEPCase (e.g., corn and sugarcane). Many European countries have jelly purity laws that do not allow sweeteners in jelly. Countries in North America have no restrictions on sweeteners in jelly. Thus, North American jellies often contain sweeteners produced from plants with PEPCase. 7a. Which continent produces jelly from plants that are likely to exhibit high rates of photorespiration? (Europe or North America; 1 point) 7b. Which continent produces jelly from plants that contain relatively high concentrations of malate? (Europe or North America; 1 point) 7c. Which continent produces jelly from plants that contain relatively high concentrations of phosphoenol pyruvate? (Europe or North America; 1 point)

Explanation / Answer

7a. Europe. As PEPcase converts phosphoenol pyruvate into oxaloaxetate and this involves in Calvin cycle ..and photo respiration is not in C4 plants which have max utilization of PEPcase.. PEPcase is found less when photorespiration is more i.e they are C3 plants .

7b.North America. As oxaloacetate undergoes Calvin cycle forming malate ..for malate to be formed from oxaloacetate it needs more PEPcase.

7c. Europe. As phosphoenol pyruvate is converted into oxaloacetate by PEPcase ..and here the quantity of phosphoenol pyruvate is high suggesting that there is less PEPcase as in Jellies of Europe.
