What does FADH2 do in ETC?
FADH2 is an electron carrier similar to NADH, but only the second protein in the ETC accepts FADH2 electrons. So FADH2 is used in the ETC, but it produces less ATP due to it only entering the second protein in the ETC.
Is NADH an electron acceptor?
Not exactly. It is true that NAD is formed during electron transport chain, however, it's not a direct product. NADH is an electron carrier that dumps its electron to the electron transport chain, which oxidizes it into NAD. NAD then goes back to become reduced by glycolysis or citric acid cycle.
After electrons leave photosystem II they go into an electron transport chain of three protein complexes Where do they go after that electron transport chain?
They go into photosystem I.
What are a series of carrier proteins?
Active transport involves carrier proteins. Carrier proteins bind themselves to particles and transport them to highly concentrated areas within a cell.Facilitated diffusion and active transport require carrier proteins.
How is the function of NAD plus similar to that of NADP plus?
Both NAD+ and NADP+ are coenzymes involved in redox reactions in cells. They both act as electron carriers, accepting and donating electrons during metabolic processes. NAD+ is primarily involved in catabolic reactions, while NADP+ is involved in anabolic reactions.
What compound is NADH converted to when it transfers high energy electrons to the first electron carrier?
NADH is converted to NAD+ when it transfers high-energy electrons to the first electron carrier of the electron transport chain.
In the electron transport chain what keeps the electrons moving along from the first to the last chemical carrier?
NITROGEN
What are the electron carrier molecules of aerobic respiration?
The electron carrier molecules of aerobic respiration are NADH and FADH2. These molecules transport electrons from the citric acid cycle and glycolysis to the electron transport chain in the mitochondria, where ATP is produced through oxidative phosphorylation.
What causes the electrons to become excited and move into the electron transport chain?
Electrons become excited in the electron transport chain due to the energy input from electron carrier molecules like NADH and FADH2. These electron carriers donate the electrons to the proteins in the chain, creating a flow of electrons that drives the production of ATP.
What allows the passage of electrons along the series of carrier molecules from higher to a lower energy level?
The electron transport chain.
Is FADH2 an electron acceptor?
No, FADH2 is in the "accepted" state. FADH+ is the form of the molecule that is able to accept electrons.
An example of an electron carrier molecule?
One example of an electron carrier molecule is NAD+ (nicotinamide adenine dinucleotide). NAD+ is involved in redox reactions, acting as a carrier of electrons during cellular respiration to help generate ATP. It accepts electrons from substrates and becomes reduced to NADH, which can then donate the electrons to the electron transport chain for ATP production.
What does FADH2 do in ETC?
FADH2 is an electron carrier similar to NADH, but only the second protein in the ETC accepts FADH2 electrons. So FADH2 is used in the ETC, but it produces less ATP due to it only entering the second protein in the ETC.
What electron carrier function in the Krebs cycle?
NAD+ and FAD are electron carriers that function in the Krebs cycle to accept and transport electrons from various reactions within the cycle. They play a crucial role in transferring these electrons to the electron transport chain for ATP production.
What compound is the source of electrons for linear electron flow?
In linear electron flow in the light reactions of photosynthesis, water is the source of electrons. The process involves the splitting of water molecules to release electrons, which are then used to reduce the electron carrier molecules in the electron transport chain.
In an electron transport chain what is the name of the main purpose you breathe to keep electrons moving along from the first to the last chemical carrier?
Oxygen
Nadh delivers electrons to an electron what?
NADH delivers electrons to the electron transport chain in the mitochondria during cellular respiration. This transfer of electrons helps to generate a proton gradient across the inner mitochondrial membrane, which drives the production of ATP through oxidative phosphorylation.
