The energy in light raises some of the electrons in chlorophyll to higher energy levels. These high-energy electrons are used in photosynthesis. Electron carriers are used to transport the electrons from chlorophyll to other molecules during photosynthesis.

Does a medium need molecules?
Mediums are made of molecules. Actually, we're all made of molecules whether we are mediums or not. We require molecules to breath, to drink, to eat, and to exist. Psychic ability has no bearing on one's need for molecules.
16 electrons need how many shells?
Three
What three things do you need for an electrical current?
protons,neutrons and electrons
What do you need to build a neutral atom?
The atom needs to have the same number of electrons as it has protons.
In order for the electrons to move they need a closed losed loop called?
A "circuit".
Why do passenger molecules need to be helped by the carrier protein?
Some molecules can't go through the cell membrane.
Why do the passenger molecules need to be helped by the carrier molecules?
Carrier proteins aid in facilitated diffusion by binding a particular substance, then altering their shape to bring that substance into or out of the cell. Those molecules can not go through the lipid layer on their own as they can not dissolve in lipids. (This is sometimes called lipophobia). This relationship is somewhat like an enzyme and substrate combination.
Why are the noble gases not likely to form compounds?
The noble gases already have their full set of valence electrons. They don't need to share or transfer any of their electrons with other molecules.
What kind of molecules are moved in active transport?
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
Why Need for carrier frequency stability?
Explain the need for carrier frequency stability in radio transmitters?
Molecules of three or more elements may be nonpolar if the geometric shape is?
Symmetrical. The bonds will need to be nonpolar for this to work since the electrons will need to be shared equally between the two atoms.
What air do you breathe to keep electrons moving along from the first to the last chemical carrier?
The air that one breathes to keep electrons moving along from the first to the last chemical carrier is oxygen. Oxygen is necessary for all life forms to exist and enable existence. For instance, humans need the trees and plant life because they take in or breathe the carbon dioxide that humans expel, and then expel the oxygen that humans need to breathe in order to maintain life.
Why are noble gases found in their pure uncombined form in nature?
The noble gases are always found pure because they already have their full set of valence electrons. They don't need to share or transfer any of their electrons with the other molecules.
How does atoms combine to form molecules?
They can combine in lots of ways. Some reactive elements will combine on their own but others need heating to combine. Noble gases (krypton, argon, xenon, helium, neon and radon) do not react (combine) with other atoms.
Why do oxygen molecules easily diffuse across a cell membrane while protein molecules do not?
Cell membrane is semipermeable and oxygen molecules have size required for easy passqge while Glucose molecules do not have that size required for easy passage.
Why does sulfur have a higher melting point than phosphorus 3 mark question?
They both have Van der Waal forces which need to be overcome, but needs minimal energy Phosphorus molecules exist as P4 molecules whereas Sulphur exists as S8. As sulphur molecules have more electrons they have stronger Van der Waal forces and need higher energy to break the bonds Mohai
What is the primary function of aerobic cellular respiration?
The oxygen is needed to break the sugar down.C6H12O6 + O2 => CO2 + H2O + EnergyMore specifically, in the electron transport chain, electrons are being transferred from one carrier to another. Oxygen is the final electron acceptor and is then released as water molecules. The only reason we need to breathe is so that we can have the oxygen molecules there to be the final electron acceptors.
