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

You are watching: Why does fadh2 yield less atp than nadh


Correct answer:

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


Explanation:

FADH2 is directly attached onto the second protein of the electron transfer chain and also therefore the electrons of FADH2 (electron carrier) are dropped off at the second protein not the first. As an outcome, the electrons from FADH2 perform not pump as much electrons across the membrane as NADH. This outcomes in a lower proton gradient produced from FADH2 then NADH and therefore less ATP production from FADH2. 


Explanation:

Remember that NADH and also FADH2 are electron carriers and execute not straight produce any power. The movement of the electrons through the electron transfer chain likewise does not produce power directly, however does develop a proton gradient that is later on offered to produce power. The activity of protons down its proton gradient through ATP synthase does, yet, geneprice energy. It actually generates approximately 30 ATP molecules per one glucose. 


Explanation:

In both cellular respiration and photosynthesis, chemiosmosis occurs. Chemiosmosis is the process in which the development of a proton gradient leads to the carry of proton down its concentration gradient to produce ATP. This occurs in the electron deliver chain in both mitochondrias and also chloroplast. In the photosynthesis it occurs when the electron is transported from photosystem II to photodevice I. 


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


Explanation:

Apoptosis is programmed cell death, and it usually 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 damage. Endocytosis and exocytosis are additionally normal cell procedures or taking up substances into the cell (endocytosis) or expelling them (exocytosis) in the develop of vesicles.


Throughout what stage of the cell cycle would certainly you mean to have actually the lowest amount of cellular expansion and synthesis taking place? 


Explanation:

The M phase is additionally recognized as mitosis, and also is the moment where the cell is ready to divide. Right now, the cell has actually synthesized enough proteins and also has actually properly replicated its DNA, so development and synthesis are not priorities.

Remember that G1, S, and G2 are all divisions of interphase. In interphase, the cell is preparing to divide by manufacturing proteins and also replicating DNA, so these three phases area a hefty focus on development and protein synthesis.


Explanation:

During G1, the cell undergoes growth as it increases in dimension and produces organelles. This is adhered to by DNA replication is S phase, further development in G2, and mitosis in M phase.


Explanation:

Interphase in the cell cycle encompasses the G1, S, and also G2 phases, as it shows the duration of expansion and DNA replication that a cell should go with to prepare for mitosis. Cell division, which occurs during the M phase, is the just percentage of the cell cycle that is not included in interphase.


Central nervous system nerve cells spfinish most of their stays in which of the complying with phases of the cell cycle?


Explanation:

Because they do not divide, main nervous mechanism nerve cells do not have to endure expansion (G1 and also G2 phases), DNA replication (S phase), or mitosis (M phase). As an outcome, they spfinish a lot of of their resides arrested in G0, a relaxing phase.


The checkallude at the finish of which phase is considered the most essential element of cell cycle regulation, as any type of potential troubles via it deserve to lead to cancer?


Explanation:

Cancer have the right to regularly be the outcome of a trouble with the checkpoint at the finish of the G2 phase, as this is the last stop for regulation before the cell undergoes department.

If this checkallude is not functioning properly, cells can undergo fast and unregulated department, leading to cancer. p53, a cancer suppressor gene, plays a key duty in this checkallude, and is typically uncovered to be mutated in cancer patients.


Explanation:

The S phase is as soon as the cell replicates its DNA, resulting in chromatid pairs that will separation acomponent throughout mitosis. The G phases are greatly dedicated to protein synthesis and cell growth. The M phase is the act of mitosis.
