Photosynthesis Process Flashcards
In light-dependent reactions, what is the input, and what is the output?
Input: H₂O, Light Energy, NADP+, ADP + P
Output: O₂, ATP, NADPH
In the Calvin Cycle, what is the input, and what is the output?
Input: CO₂, ATP, NADPH
Output: Glucose, NADP+, ADP + P
Where do the NADP+ and the ADP + P come from in the light-dependent reactions?
They come from the Calvin Cycle.
Where do the ATP and NADPH come from in the Calvin Cycle?
The Light-Dependent Reactions
In the Calvin Cycle, where does the energy come from in the ATP molecule?
The bonds between phosphate ions;
When the bonds are broken, energy is released.
What is NADP+?
It holds two high energy electrons from the Calvin cycle along with a Hydrogen ion.
What is one way the sun’s energy can be trapped in chemical form?
The conversion of NADP+ to NADPH is one way.
What is ATP synthase?
A protein in the membrane of every thylakoid cell that allows H+ ions to pass through.
What is the first step of the Calvin Cycle?
Six CO₂ molecules enter from the atmosphere. They combine with six 5-carbon molecules and make twelve 3 carbon molecules.
What is the second step of the Calvin Cycle?
The 12 3-carbon molecules are converted into higher-energy forms. The energy for this conversion comes from the ATP and high-energy electrons from the NADPH.
What is the third step of the Calvin Cycle?
Two of the 12 3-carbon molecules are removed to produce sugars, lipids, amino acids, and other compounds. `
What is the fourth step of the Calvin Cycle?
The remaining 10 3-carbon molecules are converted back into six 5 carbon molecules. These combine with 6 new 5-carbon molecules to restart the cycle.
