H3C6H5O7‚ the H’s are separated. If you simplify the equation by adding up the H’s‚ then your answer will be C6H8O7. Light reactions take place on the thykaloid membranes of the chloroplast. Light reaction requires light and water‚ and produces ATP and Oxygen. Dark reactions take place in the stroma (fluid that fills the chloroplast. It uses the ATP produced in light reactions to make glucose. • What is the role of the electron transport system? Include the reactants and the

expel oxygen. The mesophyll is bounded by the upper and lower surface of the leaf blade‚ which is covered by epidermal tissue. A vascular network runs through the mesophyll‚ providing the cell walls with water and removing the food products of photosynthesis to other parts of the plants. The leaf blade is connected to the stem through a narrowed portion called the petiole‚ or stalk‚ which consists mostly of vascular tissue. Appendages called stipules are often present at the base of the petiole.

- Cellular Respiration Assignment - 1. What two molecules are formed when a phosphate is removed from ATP? There are three phosphate groups in ATP molecule (Adenosine Triphosphate)‚ when removing one phosphate molecule‚ ADP molecule is formed (Adenosine Diphosphate). 2. What is the function of ATP? Describe the molecule. The function of ATP is storing energy within a cell. ATP is adenosine triphosphate‚ C10H16N5O13P3‚ a high energy complex‚ giving the necessary power to push metabolistic

however‚ the stored malate moves from the vacuole to a chloroplast and releases its CO2. The CO2 is then fixed in the Calvin cycle by the chloroplast‚ and the CAM pathway reduces photorespiration by generating high CO2 concentrations inside chloroplasts. This strategy saves both water and energy. 9. Explain how C4 photosynthesis is based on a spatial arrangement of structures‚ whereas CAM photosynthesis is temporally based. C4 photosynthesis is based on a spatial arrangement of structures because

materials both plants and animals take in to grow and prosper. Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae. Plants need only light energy‚ CO2‚ and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts‚ specifically using chlorophyll‚ the green pigment involved in photosynthesis. Photosynthesis takes place primarily in plant leaves‚ and little to none occurs
