Why is cellular respiration called a aerobic procecc?

Answer 1

Because it requires oxygen from the air. Oxygen is combined with carbohydrates to produce carbon dioxide and water:

C6H12O6 (aq) + 6O2 (g) → 6CO2 (g) + 6H2O

Aerobic comes from the greel "aero" meaning air, and "bios" meaning life. It refers to things which live in the presence of oxygen found in air which is 21% oxygen. Aerobic respiration means the kind of respiration typically performed by aerobic organisms. Anaerobic respiration is that respiration done in an environment devoid of "air" (meaning the oxygen part of air).

Answer 2

The single most important biochemical especially to us is " Cellular respiration ". Because this is how we derive energy from what we eat and used in some metabolic reactions and muscle contraction, nerve impulses.

or in simple "Cellular respiration" is process from which the organisms can derive energy from the metabolic reactions.

cellular respiration is starts from glucose. During cellular respiration one mole of glucose and six moles of molecular oxygen going to produce six carbon dioxide, six water molecules, and energy and 38 ATP's ( energy currency for biological system )

Under cellular respiration :

1) Glycolysis/ anaerobic cellular respiration ( breaking up glucose; gluc= sweet, ose = sugar ): It occurs completely under the absence of oxygen. so it this is called " anaerobic cellular respiration ".

where in Glycolysis the glucose molecule need 2ATP's and generates 2ATP's so it generates a net of 2 ATP's.

the byproducts of glycolysis that re-engineeredand enters in to aerobic( requires oxygen ) cellular respiration process called ;

2) Krebs cycle( aerobic cellular respiration ) : Krebs cycle generates another 2 net ATP's. This 2ATP's produces NADH.

3) Electron transport chain/ ETC ( aerobic cellular respiration ) : ETC generates 34 ATP's by using the NADH which are produced from the ATP in Krebs cycle.

this cycle requires oxygen so aerobic respiration.

that's about cellular respiration and aerobic process ( 2nd and 3rd ).

Here some important thing is some of the byproducts of the glucose ; instead of going in to Krebs and ETC cycle enters into a process called Fermentation and produces alcohol and lactic acid.

( Yeast= alcohol, called alcohol fermentation)

( Humans= lactic acid) .

Answer 3

Some clearance- Cellular respiration is an aerobic process only if it is a eukaryotic cell. In prokaryotic cell, it is always anaerobic process as the prokaryotic cells lack mitochondrion, the essential organelle required for aerobic respiration.

Now, to your answer: The eukaryotic cell receives oxygen form some source- if it is an animal cell, the oxygen is made available by respiratory system. If it is a plant cell, the oxygen is taken in through stomata. Anyway, free molecular oxygen is available to the cell. It enters the mitochondrion and occupies the last place in electron transfer system (ETS). It acts as a dust bin to receive all the de-energized electrons(from ETS) which have lost all of their energy in ATP synthesis. If oxygen were not available, the de-energized electrons will not be remmoved from ETS and there would be blockage of electron flow and ETS would be stagnated. Oxygen ensures free flow of electrons thorough the ETS. Hence the answer.

Answer 4

Cellular respiration is called an aerobic process because it utilizes oxygen. Virtually all respiration involves oxygen exchange -- that is what aerobic means. Processes that do NOT use oxygen, or occur in the absence of oxygen, are called anareobic, where "an" is the Latin/English prefix that literally means "without".

Answer 5

Cellular respiration is called an aerobic process because it requires the presence of oxygen to efficiently break down glucose and generate energy in the form of ATP. Without oxygen, cells shift to anaerobic respiration, which produces less ATP and can lead to the buildup of lactic acid.

Answer 6

Aerobic respiration involves oxygen.Oxygen is the last electron acceptor.

Answer 7

Aerobic cellular respiration has oxygen as the last electron acceptor in the electron transport chain.
