Nature Of Light
what are lights properties
Light has the properties of both a wave motion and particles (photons or quanta)
What is the formula for photosynthesis?
6CO2 + 6H2O → C6H12O6 + 6O2
Where does the light dependent reaction occur?
What is: The light dependant reaction occurs inside the thylakoid membrane?
Where does the calvin cycle occur?
What is: The calvin cycle occurs in the space inside the chloroplast called the stroma.
what chemical is brought in through CAM
CAM brings air in and traps it inside of leaves.
what is needed for plants to photosynthesize
In order to photosynthesize, plants must convert the energy in light to a form in which it can be used to synthesize carbohydrate.
What are the reactants of the calvin cycle?
6 Carbon dioxide molecules
What is the first step in the light dependent reaction?
What is: The first step in the light dependent reaction is the breakdown of water into Oxygen and Hydrogen. Electrons from the water move into photosystem 2. The electrons in photosystem 2 are then excited by sunlight and moved out on a group of protein complexes called electron transport chains.
What is the first step in the calvin cycle.
The first step is a 5-carbon molecule called RuBP binds with a carbon from CO2 in the atmosphere to create a 6-carbon molecule. This six carbon molecule splits and makes 12, 3-carbon molecules called PGA.
what does the stroma do to prevent mass loss of water
The stomata closes during the day to limit the amount of water being lost and storing carbon dioxide is used in the calvin cycle.
where does the energy for photosynthesis come from
The energy for photosynthesis is derived from sunlight
What is the product of the calvin cycle?
The glucose molecule
What is the second step in the light dependent reaction?
The second step in the light dependent reaction is the movement of electrons on the electron transport chain to photosystem one. The energy from the elections is used to pump hydrogen into the space inside the thylakoid. These lower energy electrons then arrive in photosystem 1.
What is the second step in the calvin cycle?
The second step in the calvin cycle is the 12 PGA molecules are energized by 12 NADPH and 12 ATP molecules from the light dependent reactions. The PGA becomes PGAL molecules.
whta is needed in the first compound
The first compound always need a bit of some extra ATP.
what are photosynthetic pigments responsible for
Photosynthetic pigments are the molecules responsible for absorbing solar energy and transferring the energy to the reaction center.
What are the reactants for light dependent reactions?
6 water molecules
What is the third step in the light dependent reaction?
The third step in the light dependent reaction is the electrons get energized again in photosystem 1. From here they are picked up by the electron carrier NADP+. These electrons plus one hydrogen ion creates NADPH, one product of this reaction which is used in the calvin cycle
What is the third step in the calvin cycle?
The third step of the calvin cycle is 2 PGAL molecules leave the cycle and assemble as glucose, the main product of the calvin cycle.
what are CAM and c4 used to help plants
In photosynthesis CAM and c4 are used to help plants adapt to hotter environments by storing carbon dioxide.
what is the mathematical relationship between wavelengths and energy
The amount of energy contained in a photon is inversely proportional to the wavelength, short wavelengths having higher energy than long wavelengths.
What are the products of light dependent reactions?
The oxygen molecule is the product.
What is the final step in the light dependent reaction?
The final step in the light dependent reaction is the buildup of hydrogen ions in the thylakoid space pass through an enzyme called ATP synthase. This process assembles ATP, the second product from this reaction which is used in the calvin cycle.
What is the final step in the calvin cycle?
The final step is the 6 remaining 10 PGAL molecules are rearranged into 6 5-carbon molecules or RuBP. From here the cycle will keep repeating.
what make c4 different from c3
What makes this different from c3 is the fact that C3 plants do not have special features to combat photorespiration, while C4 plants minimize photorespiration by performing carbon dioxide fixation and Calvin cycle in separate cells
