Yes. From our lectures, it was discussed that the first true cells were protozoans that lives anaerobically. Oxygen is literally a poison to them.

Did aerobic repsiration evolve before anaerobic respiration?
Aerobic means with oxygen Anaerobic means without. So, anaerobic would have to come first.
Would a marathon runner be aerobic or anaerobic?
Technically everyone is both. The first 5 minutes or so are considered anaerobic and then after that the body switches to aerobic metabolism for the remainder of the race.
Is the first step aerobic respiration the first step in anaerobic respiration?
Yes
How are glycolysis and cellar respiration related?
It is the first step. It is common to aerobic and anaerobic respiration
Are the heterotrophs the first living organisms?
The first organisms would have needed to make their own food out of what was available. This characteristic would make them autotrophic.

Which came first anaerobic or aerobic?
Anaerobic came first, because there was no oxygen in the Earth's original atmosphere.

Is a Cyanobacteria a aerobic or a anaerobic?
Cyanobacteria do not require oxygen. They are believed to have produced the first oxygen supply in the Earth's atmosphere, through the process of photosynthesis.
Which types of organisms developed first due to the early environmental condition on earth?
spongesThey were prokaryotic and anaerobic organisms developed first due to the early environmental condition on earth.
What is anaerobic and anaerobic respiration?
Aerobic cellular respiration occurs in the presence of oxygen and anaerobic cellular respiration occurs in the absence of oxygen. Without the presence of oxygen, cellular respiration cannot go past Glycolysis (the first step of cellular respiration) and will be forced to find an alternative route which is, fermentation. Hope this helped.
When does your body need to use anaerobic respiration?
for the first 90 seconds of activity or when you can no longer supply oxygen for aerobic respiration.
Why did anaerobic respiration developed first?
Because aerobic respiration wouldn't have worked very well when there was no oxygen to speak of in the atmosphere.
What were the first three types of organisms?
different species of one-celled anaerobic bacteria
