Where do the electrons used in the light dependent process come from?
A photon of light strikes chlorophyll and an excited electron is energized to a higher level and enters the transport chain. Now, here is the ultimate reason plants use water. ( aside from turgidity and other processes ) The plant " cracks " water to get electrons to replace the electrons excited from the pigment of chlorophyll. The oxygen then becomes so much waste.
Where do electrons come from and how it gains energy during the light reaction?
They come from Photosystem ll. Photosystem ll gets them by ripping the electrons off of water by a process called photolysis. Electrons gain energy first in Photosystem ll, then later in photosystem l, through the absorption of energy from light.
When light is absorbed by chlorophyll molecules the excited electrons leave the molecule What is the source of electrons that makes chlorophyll stable again?
Additional electrons used to stabilize the photosystems come from photolysis, the splitting of water using photons of light. This process yields 2 electrons per molecule of water.
How does an atom's electrons affect its radioactivity?
They don't. Electrons come and electrons go, and the nucleus doesn't much care.Radioactivity is the process of the nucleusfalling apart.
Sodium is irradiated for 2 seconds with infrared light and no electrons are ejected The same metal is irradiated for 2 seconds with ultraviolet light and thousands of electrons are emitted?
Its because the electrons need a minimum amount of energy to come out of the material. This energy is called the threshold energy.

In photosynthesis the source of electrons is?
The electrons come from water. In the light dependent stage water is split into hydrogen ions (H+), electrons and oxygen. The electrons are passed on to chlorophyll, the H+ ions combine with NADP to form NADPH and the oxygen is released.

What does energy come from to make nadaph in light reactions?
From electrons in photosystem I that are excited to a higher energy state by photons of light. Then NADP + is reduced to become NADPH
What do you think could travel faster than light a cheetah a bullet sound the space shuttle or highly energetic electrons?
Nothing can travel faster than light, but highly energetic electrons come the closest. The others aren't even close.
Why must there be two connections to a batter and to a light bulb?
The electrons must go from the battery to the light-bulb, then come back again to the battery through the other connection. If there is only one connection, there will soon (within microseconds or so) be an accumulation of electrons that will repel any additional electrons - the current will stop flowing.
Where does oxygen gas come from in photosynthesis?
The splitting of water by the process of photolysis in photosystem II. There the electrons and protons are used in the process of photosynthesis but oxygen gas is a byproduct that diffuses out of the stomata into the atmosphere.
Why the current is reduced as electrons move through a conductor?
I assume you are referring to electrical resistance. Basically, some electrons in a current will collide with atoms or other electrons, and lose energy in the process. This energy, of course, has to come from somewhere - so the current loses energy.
How do you get the air conditioning dash button light replaced on a Holden Vectra 2.2L 2001?
Remove the retaining ring to the light. The light will come out. Push the light in and turn at the same time. Reverse the process to install the new light.
