Question

In the process of aerobic respiration, the role of oxygen is
A. To couple with C to form $CO_2$ in chemiosmosis
B. To form ATP
C. To contribute $H+$ To the Krebs cycle
D. To make PGAL
D. To accept electrons from the electrons transport chain (ETC)

Answer 1

Hint: In the Electron shipping chain, the electron is transferred in the collection of coenzymes and cytochrome, which sort of within reason are widespread. Oxygen after accepting electron reacts with protons to form metabolic water, demonstrating that oxygen typically is the very last acceptor of electron on this collection, showing how in the Electron delivery chain, electron for the most component is transferred in the collection of co-enzymes and cytochrome, which is quite big.

Complete answer:
Cardio respiration in particular is the aerobic catabolism of vitamins to carbon dioxide, water, and electricity, and entails an electron transport gadget wherein molecular oxygen sincerely is the very last electron acceptor, or so that they thought. glucose ($C_6H_{12}O_6$) is oxidized to for all intents and functions produce carbon dioxide ($CO_2$) and oxygen ($O_2$) usually is reduced to for all intents and functions produce water ($H_2O$), showing how cardio respiration truly is the cardio catabolism of nutrients to carbon dioxide, water, and strength, and involves an electron shipping device in which molecular oxygen specifically is the very last electron acceptor, which truly is reasonably significant. This reaction is strongly driven reactions and "releases" power as ATP molecules, demonstrating that aerobic breathing especially is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and entails an electron delivery gadget wherein molecular oxygen commonly is the very last electron acceptor in a diffused way. Obligate aerobes sort of are organisms that require molecular oxygen due to the fact they essentially produce ATP simplest by way of cardio breathing, displaying how most eukaryotes and prokaryotes use aerobic respiratory to truly gain power from glucose, usually opposite to famous perception. Facultative anaerobes, on the other hand, literally can cardio respiratory but can switch to fermentation, an anaerobic ATP-producing procedure, if oxygen virtually is unavailable, or so that they thought.

Hence, the correct answer is option E. Oxygen accepts electrons from the electrons transport chain (ETC) in the process of aerobic respiration.

Note:
Aerobic respiration broadly speaking is the process by which organisms use oxygen to flip gas, for all intents and purposes along with fat and sugars, into normally chemical electricity, which essentially is quite sizable. The made of breathing specifically is a molecule known as adenosine triphosphate (ATP), which virtually makes use of the power stored in its phosphate bonds to energy pretty chemical reactions, basically besides showing how the product of respiration especially is a molecule called adenosine triphosphate (ATP), which without a doubt makes use of the energy stored in its phosphate bonds to power mainly chemical reactions in an essentially foremost manner.
