Which of the following is NOT one of the 3 parts that makes up ATP?
Adenine base
3 Phosphate Groups
5-Carbon Sugar (Ribose)

How is energy used in the cells?
The bond between the 2nd and 3rd phosphate is broken, converting ATP into ADP.
The bond between the 1st and 2nd phosphate is broken, converting ATP into AMP.
The bond between the 2nd and 3rd phosphate is remade, converting ADP into ATP.
The bond between the 1st and 2nd phosphate is remade, converting AMP into ATP.
True of False: Once ATP has been converted into ADP it can never be remade.
True
False
True or False: 6CO2 (Carbon Dioxide) + 6H2O (Water) + Sunlight ==> C6H12O6 (Sugar/Glucose) + 6O2 (Oxygen)
True

What is the main job of Photosystem II?
The light absorbed is used to break up water molecules into hydrogen ions (H+).
High-energy electrons move from Photosystem II into Photosystem I.
Enzymes in the membrane use the electrons to form NADPH.
The inside of the thylakoid membranes fills ups with hydrogen ions and are then moved across the thylakoid membrane.

What is the first step of the Calvin Cycle?
Energy from ATP and NADPH are used to convert the twelve 3-carbon molecules into higher energy forms.
The ten 3-carbon molecules are converted into six 5-carbon molecules.
Six carbon dioxide molecules are combined with six 5-carbon molecules to produce twelve 3-carbon molecules.
Two 3-carbon molecules are removed from the cycle to produce sugars, lipids, amino acids, and other compounds.
What is the second step of the Calvin Cycle?
Energy from ATP and NADPH are used to convert the twelve 3-carbon molecules into higher energy forms.
The ten 3-carbon molecules are converted into six 5-carbon molecules.
Six carbon dioxide molecules are combined with six 5-carbon molecules to produce twelve 3-carbon molecules.
Two 3-carbon molecules are removed from the cycle to produce sugars, lipids, amino acids, and other compounds.

The ten 3-carbon molecules are converted into six 5-carbon molecules.
Six carbon dioxide molecules are combined with six 5-carbon molecules to produce twelve 3-carbon molecules.
Two 3-carbon molecules are removed from the cycle to produce sugars, lipids, amino acids, and other compounds.
What is the fourth and final step of the Calvin Cycle?
Energy from ATP and NADPH are used to convert the twelve 3-carbon molecules into higher energy forms.
The ten 3-carbon molecules are converted into six 5-carbon molecules.
