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 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 photoactivation of chlorophyll?
The initial stage of [[photosynthesis in [[chlorophyll Molecules where the presence of [[light Energy raises the energy. It is the first event int he first phase of photosynthesis which is light-dependent reactions.it happens at the thykaloid. Chlorophyll molecules capture light energy and becomes energized electrons(e-).
What occurs during the first stage of photosynthesis?
The first stage of photosynthesis is the light dependent reactions. During this stage, photons excite the electrons that move through Photosystem I, Photosystem II, and the Electron Transport Chain to produce ATP and NADPH. The ATP and NADPH produced in this first step are then used later during the Calvin Cycle.
How are light reactants of photosynthesis important to the production of glucose?
It is the first step. First step of the photosynthesis.
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 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.
How do you determine if a molecule is over all polar or non polar by finding if it a asymmetrical or symmetrical?
First, you should determine the geometry of the molecule. How many atoms or lone pairs are associated with the central atom? Is the molecular geometry linear, trigonal planar, tetrahedral, etc. Secondly, you need to determine the electronegativity of the atoms bonded together in the molecule. Polarity is all about electronegativity and how tightly bound electrons are to particular atoms in a molecule. Lone pair electrons on the central atom are obviously quite electronegative and should be accounted for as such. Halogens and other extremely electronegative atoms will provide a strong negative charge due to their affinity for electrons. If the molecule is symmetrical it is to be expected to be non-polar, and if it is asymmetrical it would be expected to be polar, but this is not always the case. For instance, a water molecule is symmetrical, but it is polar due to the pull of the lone pair electrons of the oxygen atom.
What is the first process in the light dependent reactions of photosynthesis?
Excitation of electrons in photosystem II.
The first bond in a covalent molecule is always the sigma bond?
A sigma bond is the bond in which two atoms share the electrons.
