A central nervous system is consist of brain and spinal cord. The brain is made of the cerebrum, cerebellum, and brain stem.

The parts of the central nervous system involved in given behaviors are as follows:

Listening to music: The cerebrum in the brain is responsible for the behaviour of listening music as it functions for auditory stimuli (temporal lobe).
Realization of being thirsty: limbic system in brain is responsible for the regulation of thirst.

Feel that soda is no longer cold: Hypothalamus in brain controls the sense of temperature felt by the body.

Decide to invite a friend over: The cerebrum functions for thinking and decision making.

If acetyl-CoA is labeled with 14C at its methyl group, how many rounds of the cycle are required before 14CO2 is released?

Elis [28]

Answer:

14 CO₂ will be released in the second turn of the cycle

Explanation:

Complete question goes like this, "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?"

The answer to this is;

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.

Why does evolution have to with change over time?

Naddik [55]

Evolution is the change in an animal over time. Evolution causes this one animal to branch out into many different species of animals.
How evolution starts- There is a mutation in the genes of one animal. If the mutation helps the animal, than the animal breeds and passes on this mutation. This is natural selection. Natural selection is the starting point of evolution because all of the helpful mutations get passed down to change the species over time for the animals' benefit.
I really hope this helps you
