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.
Facilitated diffusion does not require energy because it relies on the use of carrier proteins to transport molecules across a cell membrane down their concentration gradient. These carrier proteins facilitate the movement of specific molecules such as glucose or ions without the need for ATP or energy input.
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.
10 electrons would need 2 shells to accommodate them. The first shell can hold up to 2 electrons, while the second shell can hold up to 8 electrons.
16 electrons would fill up the first four shells in an atom: 2 electrons in the first shell, 8 electrons in the second shell, 4 electrons in the third shell, and 2 electrons in the fourth shell.
To make the atom equal you get another atom that has the amount you need to make 8 on the Bohr model, for instance Mg (Magnesium) and O (oxygen) Mg has two electrons on the outer shell/ring and oxygen has 6 electrons, to make it equal you would either add two Mg to O or you could add six O to Mg, then it would be written like Mg ^2+ + O^2- --> MgO
Carrier molecules in the plasma membrane are actually used for both active and passive transport of molecules. In active transport, carrier proteins use energy to move molecules against their concentration gradient, while in passive transport, carrier proteins facilitate the movement of molecules down their concentration gradient without the need for energy input.
Some molecules can't go through the cell membrane.
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.
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.
Large molecules such as proteins and polysaccharides are usually too large to be transported by carrier proteins. These molecules are often transported through other mechanisms like endocytosis or exocytosis.
Explain the need for carrier frequency stability in radio transmitters?
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.
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.
They are used in both, in passive the molecules move in , then change the shape then leave and the entering and leaving are both by diffusion. in active transport molecules move in by diffusion, change the shape of the carrier protein, then because theyre moving into the cell where the molecule is in higher concentration energy is required to push the molecules out of the carrier proteins, this energy comes from ATP which is supplied to the carrier proteins.
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.
