Why do most complex organisms undergo aerobic respiration rather than anaerobic respiration?

During anaerobic respiration, such as fermentation, pyruvic acid and NADH form the products of alchohol and carbon dioxide and NAD+. In aerobic respiration there are many more steps in the Krebs cycle to make the products of carbon dioxide, NADH, ATP, and FADH2 from pyruvic acid.Therefore aerobic respiration is much more complex than aerobic respiration.

∙ 11y agoets start by defining respiration first.
Cellular respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products
it is required by the cell to yield Energy, which is very obvious need of the cell. besides this, respiration produces many intermediates that directly or indirectly participate in the anabolic pathways of the cell (anabolism is the process of building complex molecules from simple forms). respiration or catabolic pathways also set a flux in the cell, which can be used by the cell to transfer molecules under the gradient produced.
there could be more to add to it

How could evolution of aerobic respiration have permitted evolution of more complex organisms?
An oxygen-based metabolism provides more energy than an anaerobic metabolism, allowing for a larger volume-to-surface ratio of organisms. So organisms could grow larger, allowing their tissues to specialize in various ways, which means increasing complexity.
How is oxygen is obtained by complex organisms and then used during cellular respiration?
well, simply put it this way. by cellular respiration fermentation and photosynthesis are dying in a hole. LOLOLOLOLOLOL
What is the equation using cellular respiration?
6C6H12O6 + 6O2 --> 6CO2 + 6H2O + 34ATP The equation shown above is the chemical equation of aerobic cellular respiration. It takes in a complex sugar, glucose, and breaks it down in order to harvest its stored up energy.
How do organisms respire?
They dont
Is it true that Photosynthesis and respiration processes show plant cells to be very simple in design?
that is very false, they are very complex organisms I hope this helped ^^
Is alcoholic fermentation aerobic?
Yes. In more complex organism, in which aerobic respiration is the main process to make ATP, when your body does have enough oxygen it goes though anaerobic respiration. In simpler organisms, which don't require much ATP, anaerobic would be the main process.

What is the difference between aerobic respiration?
Aerobic respiration requires oxygen, whereas anaerobic respiration occurs in the absence of oxygen. Aerobic respiration is completed in three steps viz, Glycolysis, Kreb's Cycle and Electron transport chain; whereas anaerobic respiration is completed in Glycolysis. Aerobic respiration involves carbon dioxide as the major excretory by-product, whereas in anaerobic respiration, along with carbon dioxide, ethyl alcohol (in case of plants) and lactic acid (in case of animals) is liberated.
What is oxidative respiration?
Oxidative respiration is an anabolic process where complex molecules are built up. This is how our bodies produce energy through aerobic metabolism that uses oxygen and has a byproduct of water.

What occurred to other species when oxygen levels rose on earth?
When oxygen levels rose on Earth, it resulted in the diversification and expansion of oxygen-dependent organisms, including the development of more complex life forms. This increase in oxygen levels formed the basis for the evolution of aerobic respiration and allowed for the colonization of new ecological niches. However, these changes may have also put pressure on anaerobic organisms, leading to their decline in certain environments.

Explain why fermentation takes place within human muscle cells?
In the absence of the gas oxygen, certain living things are capable of breaking down carbohydrates (starches and sugars) to form alcohol and carbon dioxide gas. This process is known as anaerobic respiration or fermentation, and it has been used for centuries in the production of certain foods and beverages.
What is the breakdown of pyruvic acid in the presence of oxygen called?
The breakdown of pyruvic acid in the presence of oxygen is called aerobic respiration. At the beginning of aerobic respiration, acidic acid bonds to a molecule called coenzyme A to form Acetyl CoA.
What is the maening of respiration?
it converts energy in food into a more usable form
