why does fadh2 yield less atp than nadh

FADH2 makes less ATP because it enters the electron transport chain at a later stage than does NADH

. The electron transport chain is made of carrier molecules assembled into 3 protein complexes, and the passage of an electron through each complex generates enough energy to make roughly 1 ATP per complex. Click to see full answer.

Why doesn't FADH2 produce 3 ATP?

More specfically, FADH2 doesn't create 3 ATP because its redox potential is only slightly lower than the complex in the ETC where the electrons from FADH2 enters (Complex II). Remember that the complexes in the ETC go from more negative to more positive Redox potential as you move further down the line.

What happens to the FADH2 and NADH that are generated in secondary metabolism?

The FADH 2 and NADH that are generated in secondary metabolism are transported to the inner mitochondrial membrane where they give up their H ions to the almighty course of ATP synthesis in the following steps:

What is the difference between NADH and FADH?

For the MCAT, we only need to understand that NADH drops off the electrons in the first complex, while the FADH drops off electrons in the Q complex, which skips complex I and misses out on making the same ATP as an NADH would. You must log in or register to reply here.

How many ATP does NADH produce per electron transport chain?

The electron transport chain is made of carrier molecules assembled into 3 protein complexes, and the passage of an electron through each complex generates enough energy to make roughly 1 ATP per complex. NADH enters the cycle at the first complex, so NADH produces 3 ATP.

What is the difference between ATP and ATP?

2-ATP is a common intermediate between catabolic and anabolic pathways. 3-ATP is used for the long-term storage of energy and so is often found in storage granules. 4-anaerobic organisms are capable of generating ATP via respiration. 5-ATP can be generated by the flow of protons across protein channels.

What does a cell not require?

c) a cell does not require ATP. d) cells can use the energy from the proton gradient for function other than producing ATP, such as heat generation. cell can use the energy from the proton gradient for functions other than producing ATP, such as heat generation.

Does cyanide reduce cytochrome A3?

d)Cyanide permanently reduces cytochrome a3, preventing other components to change into the oxidized state. This causes the proton gradient to break down, stopping ATP synthesis. Cyanide permanently reduces cytochrome a3, preventing other components to change into the oxidized state.
