Correct answer: B). Idiopathic

An idiopathic disease is any disease or disorder, which is caused due to an unknown cause or mechanism.

It means a disease of its own kind.

Example: Acute idiopathic polyneuritis, idiopathic pulmonary fibrosis etc.

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.

Scientists can determine the age of a layer of rock by...?
Alexxandr [17]

Answer:

B) Identifying the minerals within it

Explanation:

Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date the age of rock layers.
