Question

Indicate whether each of the following statements is true, false, or does not provide enough information for you to make a decision. Sort each statement into the appropriate bin. ResetHelp Sucrose is synthesized in the chloroplast stroma and exported from photosynthetic cells to provide energy and reduced carbon for nonphotosynthetic plant cells.The enzyme rubisco is unusual in that, depending on conditions, it exhibits two different enzymatic activities.Ninety percent of the solar energy collected by a photosystem complex is absorbed when photons strike a special pair of chlorophyll molecules at the reaction center of the complex.The energy requirement expressed as ATPATP consumed per molecule of carbon dioxide fixed is higher for a C3C3 plant than for a C4C4 plant.The ultimate electron donor for the photosynthetic generation of NADPHNADPH is always water.

Answer 1

1) Sucrose is synthesized in the chloroplast stroma and exported from photosynthetic cells to provide energy and reduced carbon for non photosynthetic plant cells. - FALSE

2) The enzyme rubisco is unusual in that, depending on conditions, it exhibits two different enzymatic activities. - TRUE

3) Ninety percent of the solar energy collected by a photosystem complex is absorbed when photons strike a special pair of chlorophyll molecules at the reaction center of the complex. - FALSE

4) The energy requirement expressed as ATP consumed per molecule of carbon dioxide fixed is higher for a C3 plant than for a C4 plant. - FALSE

5) The ultimate electron donor for the photosynthetic generation of NADPH is always water. - FALSE
