Does FADH2 produce more ATP than NADH?
Does FADH2 produce more ATP than NADH?
FADH2 Yield Less ATP Than NADH because complex II of the electron transport chain does not pump out protons during oxidative phosphorylation.
Does NADH produce the most ATP?
Electron transport chain This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP.
Does ATP or NADH have more energy?
(NAD has low energy, NADH has higher energy). NADH has many fewer uses in the cell than ATP. It is normally converted into ATP in the mitochondrial electron transport chain if oxygen is present. If no oxygen is present, then NADH builds up and the cell can run completely out of NAD.
How do NADH and FADH2 make ATP?
The electron transport chain contains a number of electron carriers. These carriers take the electrons from NADH and FADH2, pass them down the chain of complexes and electron carriers, and ultimately produce ATP. ATP synthase uses the energy from this gradient to synthesize ATP.
How many ATP can NADH and FADH2 yield?
One molecule of NADH can yield three ATP and one molecule of FADH2 can yield two ATP. These numbers are not exact because an approximate number of H+ ions is required to move across the inner mitochondrial membrane for the synthesis of each molecule of ATP.
Why does NADH produce more ATP than FADH2 quizlet?
FADH2 produces fewer ATP molecules than NADH when it passes its electrons down the electron transport chain because FADH2 only activates 2 proton pumps, while NADH activates 3 proton pumps.
Why is NADH higher energy than FADH2?
FADH2 produces less ATP then NADH because the electrons for FADH2 are dropped off at the second protein of the electron transport chain. FADH2 produces less ATP then NADH because NADH has more energetic electrons. FADH2 produces less ATP then NADH because FADH2 produces a larger proton gradient.
Why does FADH2 year old less ATP then NADH?
Why does FADH2 yield less ATP than NADH? FADH2 electrons enter the electron transport chain at a lower energy level. This would mean lower energy yields.
