During pyruvate processing, two carbons from pyruvate combine with ____.

Biology
1 answer:
Oduvanchick [21]3 years ago
5 0

<span>The correct answer is b: Coenzyme A.</span>

During the process of pyruvate oxidation, acetyl CoA molecule is produced. Pyruvate oxidation is the link between glycolysis and Krebs cycle and it converts pyruvate (three-carbon molecule) into acetyl-CoA ( two-carbon molecule attached to Coenzyme A). NADH is produced and one CO2 released. AcetylCoA is the substrate for the next stage of cellular respiration, citric acid cycle.

lozanna [386]

Answer:

No it would not be useful for cell.

Explanation:

RNA polymerase uses only one strand of DNA which is called the template strand for the synthesis of mRNA. The other strand which is not used to make mRNA is called the coding strand.

If an RNA polymerase is designed which transcribe both the strand than two different strands of mRNA will be generated that will have different nucleotide sequences and will code for different proteins. So one strands will generate a protein which have different amino acids sequence that will complicate the overall process for the cell.

Another problem is if two RNA strands are formed then they can form a double helix and the ribosome might not be able to bind on them and translation might stop. Therefore it would not be useful for cell.

1. Why is the nitrogen cycle important?
Temka [501]

Answer:

Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow.

During the cell cycle, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell
Yuliya22 [10]

Uncontrolled production of cyclins will most likely result in uncontrolled division of the cell.

CELL DIVISION:

  • Cell division is a biological process that every cell undergoes to replicate themselves. It is the process by which cells are multiplied in living organisms.

  • According to this question, proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell replication. However, at the end of the cycle, the cyclins are degraded to prevent further signaling for the cell to divide.

  • In a case whereby there is an uncontrolled production of cyclins, this will most likely result in uncontrolled division of the cell because cyclins stimulate cellular division.
