Answer: b. Acetyl Co-A
Explanation:
Acetyl CoA produced through pyruvate, amino acids, and fatty acids are oxidized in the Krebs cycle in CO2, obtaining as products NADH, FADH2 and GTP (ATP). Parallel to this oxidation, the Krebs cycle produces compounds used as precursors for biosynthesis. As it is a cycle, an oxaloacetate molecule could, in principle, oxidize an amount indefinite of acetyl CoA. Acetyl-CoA is formed from the oxidative decarboxylation of pyruvate, sequentially performed by pyruvate dehydrogenase -PDH (complex multi enzymatic of 3 enzymes), in the mitochondrial matrix.
Answer:
The earliest known life-forms are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 Gya (billion years ago), relatively soon after the oceans formed 4.41 Gya, and not long after the formation of the Earth 4.54 Gya.
Explanation:
Answer:
A.Testable hypotheses
it makes the most sense out of the rest
Answer:
telomere hypothesis
Explanation:
Telomere hypothesis -
Telomere -
It is the area where there are repetitive nucleotide sequence at the very end of the chromosome that does not allow the ends from fusing with the other chromosomes and even from deteriorating .
<u>according to the hypothesis , the cells have shorter DNA sequence which divide throughout the life .</u>
<u>hence , the correct term for the given statement is - telomere hypothesis . </u>
I think the answer is A
C6H12O6 + 02
