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.
What else can I help you with?
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 did these first organisms respire and feed?
The first organisms likely obtained energy through anaerobic respiration, utilizing simple molecules like glucose. They may have absorbed nutrients directly from their surroundings through processes like diffusion or osmosis. Over time, these early organisms evolved more complex mechanisms for respiration and feeding as they diversified and adapted to different environments.
What is the site of reaction for respiration?
The site of respiration in cells is primarily the mitochondria, where the process of aerobic respiration takes place. This process involves the breakdown of glucose to produce energy in the form of ATP through a series of complex biochemical reactions.
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 was the evolutionary advantage of the proto-eukaryotes that engulfed aerobic bacteria but did not digest them?
it is a part of the origin of eukaryotes by a process called endosymbiosis. The engulfed prokaryotic cells later became mitochondria and chloroplast in today's living organisms Campbell and Reece; Biology, 7th edition
Do mealworms perform aerobic or anaerobic respiration?
Mealworms primarily perform anaerobic respiration, breaking down their food in the absence of oxygen to produce energy. This is because they have a simple respiratory system and do not require as much oxygen as complex organisms.
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.
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.
The appearance of what element on earth allowed life to flourish?
The appearance of oxygen in Earth's atmosphere allowed life to flourish by enabling aerobic respiration, a process that produces more energy for living organisms compared to anaerobic respiration. Oxygen also played a crucial role in the development of complex multicellular organisms.
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 was the effect of oxygen on earth?
The presence of oxygen on Earth allowed for the development of aerobic respiration, which is more efficient at producing energy than anaerobic respiration. This led to the evolution of more complex organisms and paved the way for the diversity of life we see today. Additionally, oxygen in the atmosphere served as a protective layer, absorbing harmful ultraviolet radiation from the sun.
How did oxygen affect the evolution of live?
The presence of oxygen in Earth's atmosphere allowed for the evolution of aerobic respiration, which is a more efficient way to generate energy than anaerobic respiration. This led to the development of more complex organisms with higher energy demands. Additionally, oxygen played a role in the formation of the ozone layer, which protected life from harmful ultraviolet radiation.
The differences between prokaryotic and eukaryotic aerobic respiration?
In prokaryotic cells, aerobic respiration occurs in the cytoplasm and cell membrane, while in eukaryotic cells, it occurs in the mitochondria. Eukaryotic cells produce significantly more ATP through aerobic respiration compared to prokaryotic cells. Additionally, eukaryotic cells have specialized organelles and complex processes that enhance aerobic respiration efficiency.
How did these first organisms respire and feed?
The first organisms likely obtained energy through anaerobic respiration, utilizing simple molecules like glucose. They may have absorbed nutrients directly from their surroundings through processes like diffusion or osmosis. Over time, these early organisms evolved more complex mechanisms for respiration and feeding as they diversified and adapted to different environments.
Which was the characteristic of life after the oxygen revolution?
After the oxygen revolution, life on Earth became more diverse and complex. Organisms evolved to utilize oxygen for respiration, enabling them to extract more energy from their food and leading to the development of multicellular organisms. This eventually paved the way for the emergence of complex life forms like plants and animals.
What was the impact that the addition of oxygen to the atmosphere had on the organisms that lived on earth?
To the organisms that produced the oxygen as a waste gas of a anaerobic metabolism, the impact was bad and severely impacted them to the point of extinction. They are now the extremeophiles. To the developing anaerobes of the seas this addition of great amounts of oxygen was the impetus to their adaptive radiation all through the oceans of the earth. No until plants emerged did gas exchange change somewhat again.
What is the site of reaction for respiration?
The site of respiration in cells is primarily the mitochondria, where the process of aerobic respiration takes place. This process involves the breakdown of glucose to produce energy in the form of ATP through a series of complex biochemical reactions.
