The correct option is B.
The field of science is very dynamic and it thrives on discovery of new evidences. When new evidence are found for a particular phenomenon, the existing phenomenon has to be adjusted to fit the new discovery. Air pollution was once named to be responsible for global cooling because enough evidence was not available then to prove otherwise but now overwhelming evidences show that pollution is responsible for global warming.<span />

vekshin1

Answer: Exons

Explanation:

In eukaryotic cell the primary transcript are very long the contains coding region (exons) and non coding region (introns)

The parts of the gene sequence that are expressed (coding region) in the protein are called exons, because they are expressed, while the parts of the gene sequence that are not expressed in the protein are called introns, because they come in between the exons.

Intron is a portion of a gene that does not code for amino acids. These Intron sequence are cleaved out and exons are spliced (I. E combine together) to form the mature mRNA molecule.

Exons are the mRNA parts that are kept and used to make protein.

What would happen to the concentrations of Pyruvate, NADH and intermembrane H+ if the ETC stopped working?
STatiana [176]

Answer:

"Proton decreases" would be the right approach.

Explanation:

  • The Kreb cycle or system plays a key role throughout a matrix of mitochondria. 3 NADH, 2 FADH2 as well as 1 ATP are synthesized.
  • Whenever the Kreb process has been halted, the acetyl CoA throughout the Kreb cycle has not been used. Pyruvate doesn't at all, disintegrate via acetyl CoA. Therefore in cells, pyruvate accumulates.
  • Unless the Kreb loop is halted, therefore the concentration of NADH and FADH2 declines.

Thus, they aren't used for the transportation chain of electrons. This is also why protons have not been discovered to be injected towards intermembrane space.
