7. The H. sapiens genome is -3 billion base pairs while the A. thaliana genome is -135 million base pairs, however both have -30,000 genes. What accounts for the size difference between the 2 organisms? A. Humans have multiple copies of each gene, while plants only have one B. Plants lack non-coding regions C. Non-coding regions are far more expansive in humans than in plants D. A. thaliana has multiple, redundant copies of all its genes 8. What happens to pyruvate between exiting glycolysis and entering the Krebs cycle? It is transported unchanged - or - it is converted to Acetyl-CoA 9. What drives glycolysis and the Krebs cycle? A. Hydrogen ion disequilibrium within the intermembrane space B. An excess of NAD C. A deficit of ATP D. All of the Above E. A and B F. B and C

Explanation / Answer

ans 7...c...non coding regions are far more expansive in humans than in plants

the non coding sequence are far more in number in humans than plants which accounts for this much difference in number of base pair

ans 2..it is converted to acytyl coenzyme A

end product of glycolysis is pyruvate but it doesn't entr the krebs cycle as such.it is first converted to acytyl coenzyme A by enzyme pyruvate dehydrogenase

ans3...C...A deficit of ATP

glycolysis and krebs cycle produces ATP.whenever there is deficiency of ATP, glycolysis and krebs cycle get accelerated.thus ATP deficit drives this.
