Answer:
14 CO₂ will be released in the second turn of the cycle
Explanation:
<u>Complete question goes like this</u>, "<em>The CO2 produced in one round of the citric acid cycle does not originate in the acetyl carbons that entered that round. If acetyl-CoA is labeled with 14C at the carbonyl carbon, how many rounds of the cycle are required before 14CO2 is released?</em>"
<u>The answer to this is</u>;
- The labeled Acetyl of Acetyl-CoA becomes the terminal carbon (C4) of succinyl-CoA (which becomes succinate that is a symmetrical four carbon diprotic dicarboxylic acid from alpha-ketoglutarate).
- Succinate converts into fumarate. Fumarate converts into malate, and malate converts into oxaloacetate. Because succinate is symmetrical, the oxaloacetate can have the label at C1 or C4.
- When these condense with acetyl-CoA to begin the second round of the cycle, both of these carbons are discharged as CO2 during the isocitrate dehydrogenase and alpha-ketoglutarate dehydrogenase reactions (formation of alpha-ketoglutarate and succinyl-CoA respectively).
Hence, 14 CO₂ will be released in the second turn of the cycle.
The name that is given to cell division in prokaryotes is C) Binary Fission.
The number of mitochondria per cell varies widely; for example, in humans, erythrocytes (red blood cells) do not contain any mitochondria, whereas liver cells and muscle cells may contain hundreds or even thousands. The only eukaryotic organism known to lack mitochondria is the oxymonad Monocercomonoides species.
The United States Constitution is the world's longest continually operating written charter of governance. It was prepared in 1787, adopted in 1788, and entered into force in 1789.
The first three words of it, "We The People," indicate that the American government's goal is to serve its people.
<h3>What form of government evolved in the aftermath of the American Revolution?</h3>
The powers of the national government were specified in the Articles of Confederation following the United States' declaration of independence from Great Britain.
In order for the Constitution to be ratified by all 13 states, the participants in the Constitutional Amendment had to reach a number of agreements.
Thomas Jefferson authored the Declaration of Independence in 17 days. On July 2, 1776, Congress resolved to secede from the United Kingdom. On July 4, 1776, Congress approved the Declaration of Independence, which became known as Independence Day.
