FADH2 produces less ATP then NADH bereason the electrons for FADH2 are dropped off at the second protein of the electron deliver chain.

You are watching: Why does nadh produce more atp than fadh2

Correct answer:

FADH2 produces less ATP then NADH bereason the electrons for FADH2 are dropped off at the second protein of the electron transfer chain.


FADH2 is straight attached onto the second protein of the electron transport chain and therefore the electrons of FADH2 (electron carrier) are dropped off at the second protein not the first. As an outcome, the electrons from FADH2 carry out not pump as a lot electrons across the membrane as NADH. This outcomes in a reduced proton gradient created from FADH2 then NADH and also therefore much less ATP production from FADH2. 


Remember that NADH and also FADH2 are electron carriers and do not directly create any power. The motion of the electrons with the electron transfer chain also does not produce energy directly, however does produce a proton gradient that is later offered to create power. The movement of proloads down its proton gradient with ATP synthase does, however, generate energy. It actually generates approximately 30 ATP molecules per one glucose. 


In both cellular respiration and also photosynthesis, chemiosmosis occurs. Chemiosmosis is the procedure in which the development of a proton gradient leads to the transfer of proton dvery own its concentration gradient to create ATP. This occurs in the electron deliver chain in both mitochondrias and chloroplast. In the photosynthesis it occurs once the electron is transported from photosystem II to photodevice I. 

When a cell"s DNA has actually end up being damaged beyond repair, the cell undergoes which of the following processes?


Apoptosis is programmed cell death, and also it typically occurs once the DNA of the cell is damaged beyond repair.

Photosynthesis and glycolysis are normal metabolic procedures of the cell, and also would certainly not result from irreversible damages. Endocytosis and also exocytosis are additionally normal cell procedures or taking up substances right into the cell (endocytosis) or expelling them (exocytosis) in the develop of vesicles.

Throughout what phase of the cell cycle would you suppose to have the lowest amount of cellular expansion and synthesis taking place? 


The M phase is additionally recognized as mitosis, and also is the moment where the cell is all set to divide. At this time, the cell has synthesized sufficient proteins and has effectively replicated its DNA, so development and synthesis are not priorities.

Remember that G1, S, and G2 are all departments of interphase. In interphase, the cell is preparing to divide by synthesizing proteins and also replicating DNA, so these three phases place a heavy emphasis on growth and protein synthesis.


During G1, the cell undergoes development as it rises in size and produces organelles. This is followed by DNA replication is S phase, further expansion in G2, and also mitosis in M phase.


Interphase in the cell cycle encompasses the G1, S, and also G2 phases, as it shows the duration of growth and also DNA replication that a cell must go via to prepare for mitosis. Cell division, which occurs in the time of the M phase, is the just percentage of the cell cycle that is not had in interphase.

Central nervous system nerve cells spend most of their lives in which of the following phases of the cell cycle?


Due to the fact that they execute not divide, central nervous device nerve cells carry out not have to endure development (G1 and G2 phases), DNA replication (S phase), or mitosis (M phase). As a result, they spfinish the majority of of their resides arrested in G0, a resting phase.

The checkpoint at the end of which phase is taken into consideration the many crucial facet of cell cycle regulation, as any potential troubles with it can lead to cancer?


Cancer can often be the result of a problem through the checksuggest at the finish of the G2 phase, as this is the last stop for regulation before the cell undergoes division.

If this checkpoint is not functioning efficiently, cells can undergo quick and also unregulated division, causing cancer. p53, a cancer suppressor gene, plays a crucial role in this checksuggest, and also is commonly found to be mutated in cancer patients.

The S phase is when the cell replicates its DNA, causing chromatid pairs that will certainly break-up apart throughout mitosis. The G phases are greatly dedicated to protein synthesis and also cell expansion. The M phase is the act of mitosis.
