Incorrect Statement Regarding ETC
Explanation:
Electron Transport Chain (ETC) is a metabolic pathway that involves a series of redox reactions that release energy and synthesize ATP. It is the final stage in the process of cellular respiration.
During ETC, electrons from NADH and FADH2 are transported along a chain of electron carriers, which are organized into four protein complexes (I-IV) and a mobile electron carrier called coenzyme Q. The electrons are finally accepted by oxygen, which combines with protons to form water.
The energy released during the transfer of electrons is used to pump protons from the mitochondrial matrix to the intermembrane space, creating a proton gradient. This gradient is used by complex V, also known as ATP synthase, to synthesize ATP from ADP and inorganic phosphate.
The statement that is incorrect is option D, which states that one molecule of NADH H gives rise to 2 ATP molecules, and one FADH2 gives rise to 3 ATP molecules. The actual values are:
- One molecule of NADH H gives rise to 2.5 ATP molecules.
- One molecule of FADH2 gives rise to 1.5 ATP molecules.
This is because NADH donates its electrons at complex I, whereas FADH2 donates its electrons at complex II. Complex I pumps more protons than complex II, hence more ATP is synthesized when NADH is the electron donor.
Overall, the ETC is a crucial process in cellular respiration, as it generates most of the ATP needed for cellular activities.
