They do not participate in the Calvin cycle b. They use PEP carboxylase to initially for CO2 C. They are adapted to cold, wet climates d. They conserve water more efficiently 73. Explain the difference between 74. How is cell cycle regulation a 75. Diagram an enzymatic reaction in oxidation and reduction "coupled reaction" action. Label the enzyme, substrate, active site, and product. 76. Diagram and label an ATP molecule Explain where energy is stored and how it works 77. How are NAD+ and FAD similar? 78. Photosynthetic organisms, such as plants, algae, and certain bacteria capture the energy in sunlight and transform it into sugar molecules Other organisms eat this sugar to harvest the energy. Explain where the energy is stored in these sugar molecules, and how animals harvest it. 79. Draw a free energy diagram. Label the products, reactants, activation energy, AG and if it is endergonic or exergonic. 80. Diagram a graph that demonstrates enzymes optimal at pH of 7 &10

Explanation / Answer

72) They use PEP carboxylase initially for CO2

PEP is an important enzyme in the C4 cycle. It adds CO2 to PEP in the mesophyll cells and forms a 4 carbon compoud which then moves into the bundle sheath cells via the plasmodesmata. In these cells the CO2 is released again and the calvin cycle starts.
