What is passage of electrons along a series of carrier molecules from a higher to a lower energy level?
This is the electron transport chain.
What is energy-carrying molecule called?
carrier molecule1. A molecule that plays a role in transporting electrons through the electron transport chain. Carrier molecules are usually proteins bound to a nonprotein group; they can undergo oxidation and reduction relatively easily, thus allowing electrons to flow through the system. There are four types of carrier: flavoproteins (e.g. FAD), cytochromes, iron-sulphur proteins (e.g. ferredoxin), and ubiquinone.2. A lipid-soluble molecule that can bind to lipid-insoluble molecules and transport them across membranes. Carrier molecules have specific sites that interact with the molecules they transport. Several different molecules may compete for transport by the same carrier. See transport protein.
What uses energy from the high-energy electrons to transport hydrogen across the thylakoid membrane?
Electron transport chain
Carrier proteins do not require energy to transport amino acids into a cell?
diffusion
Transport chain series of proteins embedded in a membrane along which energized electrons are transported as electrons are passed from molecule energy is released?

What allows the passage of electrons along the series of carrier molecules from higher to a lower energy level?
The electron transport chain.
Which organelle makes energy stored in highenergy compounds available for the cell?
Mitochondrian
Why do high-energy electrons need carrier molecules?
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.
What is the carrier for energy and high energy electrons during glycolysis?
nadh!
What is the energy of the high energy electrons used for every time high energy electrons move down the electron transport chain?
To transport H+ ions out of the matrix.
What is the energy of the high energy electrons used for every time 2 high energy electrons move down the transport chain?
To transport H+ ions out of the matrix.

Which form of transport across the cell membrane does not require energy but a carrier protein?
Facilitated transport.
Why schottky is called hot carrier diode?
Because the energy of electrons transfer from semiconductor to metal side have more energy than the fermi energy of electrons in metal side. That's why these are called hot carrier diodes
What uses energy from the high-energy electrons to transport hydrogen across the thylakoid membrane?
Electron transport chain
Where does the electron transport chain get high energy electrons that are passed down the chains?
High-energy electrons from NADH and FADH2 are passed along the electron transport chain
