Why is pyruvate imported from the cytoplasm into the mitochondrial matrix?
grin007 [14]

Answer:

So that oxidation of pyruvate can take place in mitochondria.

Explanation:

Pyruvates is produced in the glycolysis process which occurs in the cytoplasm. So pyruvate is produced in the cytoplasm of the cell. Pyruvate is produced by partial oxidation of glucose and to be fully oxidized it has to enter in the mitochondria.

So after entering the mitochondria the pyruvate first converts into acetyl CoA than this acetyl CoA enters in the citric acid cycle and fully oxidized into CO2. This oxidation generated NADP and FADH2 which provide reducing power during oxidative phosphorylation.

Which is the best example of organisms that have been naturally selected?
KengaRu [80]
<span>Natural selection is when species learn to adapt to their environment. They could (1) differential reproduction, that is, not all organisms are able to reproduce to their fullest capacity because nature cannot simply sustain it and (2) acquire genes, that is heredity. Certain characteristics of organisms tend to survive if it continues to strive. If it survives, this trait is passed down to the next generations forgetting the other traits but only the one who could survive the environment. Therefore it is true that <span>natural selection is when ‘organisms inherit advantageous traits, and tend to reproduce more successfully than other organisms’. One best example is the extinction of other animals and some with the same species retains.</span></span>
