Draw and describe the basic structure of ATP, where its energy is located, and why it is needed by cells. |
A nitrogenous base (in this case, Adenine) attached to a 5 Carbon sugar (Ribose), which is attached to 3 phosphate groups in a row. energy is in the posphor bond. Think ATP <-> ADP and back, the breaking of that bond releases energy ,making it costs energy. ATP as you know stands for Adenosine TriPhosphate.The main role of ATP in a cell is that it acts as a transporter to carry chemical energy within the cell.ATP is also used as signalling molecule.

Know that photosynthesis cells convert solar energy to chemical energy (that then gets locked inside food molecules like glucose). |
Ok I learned it. |

|
Write the reduced equation for photosynthesis |
CO2 + H2O + energy > C6H2O6 + O2 |

List the products of the light-dependent versus the light-independent reactions. |
In summary, the light-dependent reactions uses solar power to generate ATP and NADPH2, which provide chemical and reducing power, respectively, to the sugar-making reactions of the Calvin cycle. An incidental by-product of the light-dependent reactions is oxygen. Light-independent reactions take place in plant chloroplasts. In this process sugars are made from carbon dioxide. The process, known as the Calvin cycle, uses products of the light-dependent reactions (ATPand NADPH) and various enzymes. |

Describe the organelle where the parts of photosynthesis occurs. |
Chloroplasts Like the mitochondrion, a chloroplast is a double-membrane-bound organelle, and it has its own DNA and ribosomes in the stroma.Chloroplasts contain grana, which are stacks of single membrane structures called thylakoids on which the reactions of photosynthesis occur. |

|
What factors affect photosynthesis? |
The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature. |
