Most energy that enters electron transport enters as?
FADH2 and NADH
What creates energy for the cell to use?
Cellular Respiration is the process in the cell that creates energy (ATP). Cellular Respiration is broken up into three stages; Glycolysis, the Krebs Cycle, and the Electron Transport Chain. Glycolysis takes place in the cytoplasm of the cell and is responsible for the net formation of 2 ATP molecules. The process then enters the matrix of the mitochondria where the Krebs Cycle takes place. The Krebs Cycle is responsible for the formation of 4 ATP molecules. Finally, the Electron Transport Chain is responsible for the formation of 30 ATP molecules. Therefore, for each cycle of cellular respiration, 36 molecules of ATP are produced in the cell.
Large molecules are surrounded by the cell membrane and enter the cell?
A large molecule that can not enter the cell through myosis enters the cell through by endocytosis. Endocytosis is an example of active transport.
What molecules both enters AND exits the Kreb's cycle?
Pyruvic acid enters and carbon dioxide exits.
What signaling molecules enters the cell to initiate its action?
thyroxine

Why 3 ATP are produced from one NADH but only 2 ATP from one FADH 2?
So for a real answer... The electron transport chain basically pumps out protons across the mitochondrial membrane from the matrix into the inter-membrane space, building a proton gradient. When these protons try to flow back in, they run through the ATPase and generate ATP. We can visualize this process as a chain, where electrons move through components of the chain and eject protons as they go from structure to structure. We generally think of the beginning of this chain as the place where NADH is oxidized and gives up its electrons. However, FADH2 enters from an area which can be thought of as further down the chain. So if we think of the electron transport chain as having three steps, with each step generating one ATP, then NADH starts at step one, but FADH enters the chain later at step two. So FADH will only eject enough protons for two ATP, while NADH ejects enough for three. That's a simple way of looking at it, at least.
The stages of aerobic respiration are?
First stage is Glycolysis pyruvate is then turned into Acetyl CoA and enters the Krebs Cycle Second stage is Krebs Cycle Third stage is Electron transport chain
Why does fadh2 produce fewer ATP molecules than nadh?
NADH produces 3 ATPs because it donates the proton at a "higher" location in the electron transport chain than does FADH2, which is why FADH2 produce only 2 ATPs. NADH and FADH2 donates electrons and protons into the electron transport chain.
Which type of organelle energy from glucose that has entered the cell?
In animal cells, the mitochondria are the site of energy generation. Although glucose that enters the cell is first broken down to 2 molecules of pyruvic acid, this substance enters the TCA cycle, whose products act as electron carriers in the electron transfer pathway which ultimately results the in generation of energy by the mitochondria

An electron transport chain connects photosystem1 and photosystem2?
They return to Photosystem I
What molecules both enters AND exits the Kreb's cycle?
Pyruvic acid enters and carbon dioxide exits.
How many ATP are generated in aerobic phase of respiration?
It depends wether or not NADH from glycolisis enters or not. If yes, then 38. If not, then 36 come from the electron transport chains and other ATP.
Would an asteroid fragment generate a magnetic field when entering the earth's atmosphere?
Yes, it generate a magnetic field when it enters into the earth atmosphere.
