Question

If 5 molecule of water are produced in ETS of mitochondria then find the number of ATP produced and NADH2 are oxidised :-​

Answer 1

Answer:

Concept:

If 5 molecules of water are produced in ETS of mitochondria then find the number of ATP produced and NADH2 oxidized are 30 ATP and 10 NADH2

Explanation:

The energy from carriers in the matrix is taken up by the electron transport system (ETS), which then stores it in a form that can be used to phosphorylate ADP. Flavin adenine dinucleotide (FAD) and nicotine adenine dinucleotide (NAD) are two energy carriers that have been shown to provide energy to the ETS (FAD).

The cycles of respiration lead to the production of NADH 2 and FADH2. These chemicals are generated during the Krebs cycle and glycolysis. Through the action of the electron transport system, these molecules are oxidized. In this system, electrons are given from one donor to an acceptor. These byproducts are oxidized, and the protons are then utilized to build an ATP-producing gradient. The electrons are first transferred to complex I by NADH2, and then they are transferred to complex II. More protons are pumped by ATP synthase as a result of this. Therefore, the generation of three ATPs will increase as protons increase.

Each NADH molecule in respiring mitochondria transfers two electrons to the electron transport chain, which reduces one oxygen atom (half of an O2 molecule) to generate one water molecule.

Therefore, when 10 electrons travel from mitochondrial NADH molecules through the elements of the electron transport system to molecular oxygen, 5 molecules of water are created.
