2a) Which of the following statements about pyruvate oxidation IS TRUE?
Darina [25.2K]

The true statements are:

  • Substrate level phosphorylation ocvurs during Pyruvate oxidation
  • 32 ATP molecules can be made by cellular respiration but only 2 ATP molecules when oxygen is lacking
  • Electrons move from protein to protein due to increasing electronegativity in the electron transport chain
  • ADP is phosphorylated in the matrix of the mitochondria during oxidative phosphorylation
  • ATP inhibits pyruvate dehydrogenase by feedback inhibition

<h3>What is glucose oxidation?</h3>

Glucose oxidation refers to the process in the cells in which glucose molecules are oxidized to form ATP and carbon dioxide in the presence of oxygen.

The first stage of glucose oxidation is the conversion to pyruvate.

Pyruvate is oxidized to acetylCoA.

AcetylCoA enters the citric acid cycle to produce reducing equivalents, NADH for the electron transport chain.

  • The true statements about pyruvate oxidation is that there is substrate level phosphorylation during the process
  • When there is sufficient oxygen, 36 ATP molecules can be made (theoretically) by cellular respiration. However, when oxygen is lacking, only 2 ATP molecules are made.
  • In the electron transport chain of cellular respiration, electrons move from protein to protein due to increasing electronegativity
  • During oxidative phosphorylation, ADP is phosphorylated in the matrix of the mitochondria
  • Aerobic respiration can be regulated by feedback inhibition of pyruvate dehydrogenase by ATP.

<h2><u>A</u><u>nswer:</u></h2>

<u>Translation:</u> process of protein formation is called translation .

In the process of translation, a cell reads information from a molecule called a messenger RNA  and uses this information to build a protein.  Translation involves “decoding” a messenger RNA  and using its information to build a polypeptide, or chain of amino acids .

Translation involve three major steps

• Initiation ("beginning"): in this stage, the ribosome gets together with the mRNA and the first tRNA so translation can begin.

• Elongation ("middle"): in this stage, amino acids are brought to the ribosome by tRNAs and linked together to form a poly peptide chain.

•Termination ("end"): in the last stage of translation, the finished polypeptide is released to go and do its job in the cell.

<u>Organelles involve in translation:</u>

Ribosomes: main process of translation occour at ribosomes.

Rough endoplasmic reticulum: ribosomes are located on rough endoplasmicreticulum .it bound proteins in the vesicles.Vesicles containing proteins are budded off into cytoplasm and move toward golgi apparatus for further modification .

Golgi apparatus: synthesisezed proteins are not functional . In golgi apperatus they are further modefied and processed and stored for a short time and then released toward destination.
