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.
It makes the proteins ................
The thick band of fibers that connects the two hemispheres of the brain is called the corpus callosum.
<h3>
What is the function of the corpus callosum?</h3>
- The greatest connective network in the brain is the corpus callosum, which is Latin for "tough body."
- The corpus callosum is a significant mass of more than 200 million myelinated nerve fibers that connects the two hemispheres of the brain and enables the communication between the right and left sides of the brain.
- This cerebral highway serves as a conduit for the continual exchange of sensory, motor, and cognitive information.
<h3>
What is the structure of the corpus callosum?</h3>
- The roof of the lateral ventricles is made up of part of the corpus callosum.
- Four distinct neural pathways that connect various regions of the hemispheres make up the corpus callosum. The rostrum, genu, trunk or body, and splenium are the neural pathways.
- The isthmus is a thin area that lies between the trunk and the spleen.
- The tapetum, a group of fibers from the trunk and spleen, forms the roof of each lateral ventricle.
