What is the first most immediate thing that happens when light strikes a chlorophyll molecule?
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
The first step in photosynthesis is the?
The energy from the sun, raises an energy level in the chlorophyll molecule, causing electrons to leave the molecule and travel along the electron transport chain (ETC) in a series of oxidation and reductions. In doing so it releases energy converting ADP+Pi into ATP. Photolysis (splitting of water) occurs, and the electrons produced, replace those lost. This is the Light Dependant stage as it relies on light energy
What molecule is responsible for capturing light energy in a plant?
Light is first captured by the enzyme P680 in photosystem II. Two electrons are absorbed from the incoming light energy and these move P680 to the excited state commonly written as P680*. For more information, look up "Z Scheme" this should clear up more about the entire process of light absorption and transformation into chemical energy in photosynthesis.
How many oxygen atoms are needed to start photosynthesis reaction?
In the first step of photosynthesis, which is light-dependent, two water molecules are needed to start the reaction. Each water molecule contains two oxygen atoms, so a total of four oxygen atoms are needed.
What is the first stable product of photosynthesis?
The equation for photosynthesis is below. 6CO2 + 6H2O + light energy >>> C6H12O6 + 6O2 So to answer your question, the main product in photosynthesis is a carbohydrate.
What reactant for the reaction that is powered by the sun hitting photosynthesis ll?
First of all it's not photosynthesis II, its photosystem II. well basically, the hydrogen atom within the water molecule loses its electrons and the electrons basically travels through all the photosytems via electron transport chains, towards the NADP Reductase where NADP+ is attached with the electrons from the hydrogen atoms of the water molecule to form NADPH
Water provides the needed for the first part of photosynthesis?
electrons
What molecule must first be present to begin photosynthesis?
I assume you are asking about carbon dioxide.
How many electrons are in N?
Nitrogen exists in the atmosphere as N2, a diatomic molecule. There are two ( 2 ) atoms in an N2 molecule. Each atom has 7 neutrons, 7 protons, and 7 electrons; 2 electrons in the first shell and 5 electrons in the outer shell.
What is the first most immediate thing that happens when light strikes chlorophyl molecule?
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
Is a product of the first stage of photosynthesis.?
A pair of [free] electrons: {Ever heard of the electron-transport-chain}.
What is the first most immediate thing that happens when light strikes a chlorophyll molecule?
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
What is the first step in creating a Lewis structure for a molecule?
You need to know how many valence electrons the molecule has. Then determine the number of bonding pairs, and place them in their order. Remember that all molecules strive to reach the octet rule! which means they all wants to have a full eight electrons for their outer energy level. good luck!
What stage is sunlight needed in photosynthesis?
The first stage of photosynthesis is wherein water is necessary. Water is photochemically split into oxygen, electrons and hydrogen ions together with light reaction.
The first step in photosynthesis is the?
The energy from the sun, raises an energy level in the chlorophyll molecule, causing electrons to leave the molecule and travel along the electron transport chain (ETC) in a series of oxidation and reductions. In doing so it releases energy converting ADP+Pi into ATP. Photolysis (splitting of water) occurs, and the electrons produced, replace those lost. This is the Light Dependant stage as it relies on light energy
Are electrons are energized twice during photosynthesis?
Yes because there are two photosystems (clusters of chlorophyll) which is where the sunlight is absorbed from, the electrons are energized at both times because sunlight contains photons which are the molecules that energize the electrons in the first place
What is the first process in the light dependent reactions of photosynthesis?
Excitation of electrons in photosystem II.
