Answer:
There is a need to transform the accumulation of acetyl-CoA into the ketone bodies, as one knows that acetyl-CoA is both labile and possess an enormous amount of energy. Hence, acetyl-CoA due to its unstable characteristic is not ideal for circulation within the tissues, and at the same time, the compound acetyl-CoA does not possess the tendency to pass through the cell membrane.
Due to these reasons, the conversion of acetyl-CoA into the ketone bodies is done, the ketone bodies also act as an alternative source of energy. The ketone bodies work as water-soluble correspondents of fatty acids. The production of ketone bodies generally takes place within the liver cells' mitochondrial matrix. The three forms of ketone bodies are beta-hydroxybutyrate, acetoacetate, and acetone.
The production of ketone bodies by the liver cells helps the cells of the brain at the time of starvation, as the brain cannot use fatty acids as an energy source, as the fatty acids cannot pass through the blood-brain barrier.
The third phosphodiester bond of ATP is broken mostly. The rest of the molecule is called Adenosine Diphosphate or ADP.
<h3><u>Explanation:</u></h3>
For knowing the answer, we need to know the structure of ATP first. ATP or the Adenosine Triphosphate is also called the energy currency of living cell. It has two components -
A. Adenosine which is actually an Adenine nitrogen base attached with a ribose sugar molecule.
B. Phosphate molecules.
The structure of Adenosine Triphosphate is a ribose sugar which is attached with one adenine molecule with which one phosphate ion is attached and the rest of the phosphate ions are attached with the phosphate one after the other.
Ribose - Adenine - Phosphate - Phosphate ~ Phosphate.
The last phosphodiester bond between the two phosphates is the most energetic bond containing maximum of the energy. This bond is broken during the metabolic processes to supply energy to the processes.
Cellular respiration is the consumption of oxygen by a cell within a living organism.<span> In plant seeds, the cellular respiration does not occur until the seed has absorbed moisture and released stored starches that can then be metabolized into energy for the purpose of growth</span>
Answer:
approximately 150 amino acids
Explanation:
Proteins are produced from genes via a process called gene expression. In this process, the gene-containing DNA is first transcribed into mRNA molecule, which is subsequently translated into an amino acid sequence that makes up the protein molecule.
However, during the translation process, the mRNA molecule is read in a group of three nucleotides called CODON i.e. a codon is made up of three nucleotide/nitrogenous bases. Each codon codes for a particular amino acid.
Since one codon of a mRNA that is three (3) nucleotides long codes for one amino acid, hence, strand of mRNA that is 450 nitrogenous bases long will produce a protein containing approximately (450/3) = 150 amino acids.
Answer:
1st blank: four nitrogenous bases each. (cytosine, adenine, and guanine)
2nd blank: DNA had thymine
3rd blank: RNA has uracil
