Answer: The correct answer is Kreb cycle.
Cellular respiration is defined as the oxidation of food into CO₂ ( cabon dioxide) and H₂O ( water) in order to produce energy in the form of ATP ( adenosine triphosphate).
It occurs in three stages that is Glycolysis, Kreb cycle, and Electron transport chain.
Kreb cycle occurs in the matrix of the mitochondria. It includes the oxidation of a two carbon compound that is Acetyl- CoA in order to generate a pool of chemical energy in the form of ATP, NADH, FADH₂.
On the contrary, glycolysis and fermentation occur in the cytoplasm.
Thus, mitochondria is host to Kreb Cycle of the cellular respiration.
The correct answer is: B) As land plants became more complex, animal life did as well.
This is because land could not be colonized by other organisms such as animals until land plants became established-there was nothing for animals to feed on.
So, plants were one of the earliest organisms to leave the water and colonize land.
