When light energy reaches a certain chlorophyll a molecule an electron is transferred to an Answer?
When light energy reaches a chlorophyll a molecule, it excites an electron, transferring it to a higher energy level. This energized electron is then transferred to a primary electron acceptor, initiating the process of photosynthesis. This transfer is crucial for converting light energy into chemical energy, which is used to synthesize glucose.
What element is most likely to form a negative 3 anion?
Nitride N^3- Phosphide P^3- Phosphate PO4^3-
What is the difference between excited hydrogen atom and any other atom?
Hydrogen atom = 1 proton 1 electron Hydrogen's 1 electron occupies the lowest energy level, 1s orbital. The atom is therefore in its "ground state". When a photon of correct frequency "collides" with a electron in hydrogen's 1s orbital the energy contained in the photon is transferred to the electron. The electron then gets added energy, so it is at a higher energy state. When it reaches this higher energy state the electron jumps to the next energy level and there it starts its new orbit. Hydrogen atom is now "excited" For any other atoms it is the same thing because all atoms can undergo excitation. The only difference between hydrogen's 1 electron and other atom's many electrons is WHICH ELECTRON will be "excited"
Which process stops when a ribosome reaches a stop codon?
When a ribsome reaches a stop codon, the translation process stops and a protein is released.
When the sun reaches the end of the of its life cycle the expanded part will be released into space forming a?
yes
When a pair of electrons reaches the second electron carrier enough energy has been released to pump a proton from the stroma to what location?
The proton is pumped from the stroma across the thylakoid membrane, into the thylakoid lumen. This movement of protons creates a proton gradient that is used to generate ATP through chemiosmosis during photosynthesis.
When does an electron reach a state of zero energy?
An electron reaches a state of zero energy when it is at rest or in its ground state.

NADH and FADH2 in the electron transport chain do not directly donate electrons to oxygenWhy?
The temperature in cells is not high enough. Each of the redox reactions in the electron transport chain are catalyzed by an enzyme. NADH dehydrogenase transfers electrons from NADH to ubiquinone, and cytochrome c oxidase transfers electrons from cytochrome c to oxygen. So there is no enzyme to pass the electrons directly from NADH to oxygen.
When does an electron reach zero energy?
An electron reaches zero energy when it is at rest or in a state of lowest energy level, typically in an atom's ground state.

How many electrons does a sodium ion have in its outer orbital as a sodium atom?
The outer orbital, or valence shell, around the nucleus of an atom possess what are commonly called valence shell electrons. They represent the electrons available to share with another atom for the formation of covalent bonds between atoms. For Na, or sodium, in its standard atomic state there is only 1 valence shell electron. This number increases as you go to the right across the periodic table until the number of valence shell electrons reaches 8. This is noted by the Column number (i.e. I, II, III, etc.). Carbon has four, Nitrogen has five, Oxygen has 6, and Fluorine has 7. Xenon, Argon and the other 8th column elements are called the noble gases and they all have 8 valence electrons.
What will halt the collapsing Sun's core once its fuel has been exhausted?
The collapsing Sun's core will halt when the core reaches a state of equilibrium where the inward force of gravity is balanced by the outward force of electron degeneracy pressure. This results in the formation of a white dwarf, the core remnant of the Sun after it exhausts its nuclear fuel.
Does a iPod get internet connect anywhere?
Anywhere there is a wifi signal you have the password for. 3G models can get internet anywhere their carrier's cell signal reaches.

What happens when electrons change levels?
Energy is either absorbed or released. If the electron goes from a high energy orbital to a lower energy one, a photon is emitted. When a photon is absorbed, the electron goes from low energy to high.
How does a free electron at rest move in an electric field?
A free electron at rest in an electric field will experience a force due to the field and will accelerate in the direction of the electric field. The electron will gain kinetic energy and start moving in the direction of the force until it reaches a velocity where the force due to the field is balanced by other forces acting on the electron.
