If a substance is not able to be separated by physical means but is able to be separated by chemical means, it is a compound.
Answer:
The correct option is option D which is 10 – 1 molecule of Oxaloacetate (OAA) is regenerated for every molecule of Acetyl-Coenzyme (AcCoA) used.
Explanation:
As the complete question is not given, the complete question is as below
Imagine that I start off with 10 molecules of oxaloacetate in a mitochondria. After running the TCA to generate 20 molecules of CO2, how many molecules of oxaloacetate will be left in the mitochondria (assuming oxaloacetate is being used only for TCA in these mitochondria)?
A) 30 – each molecule of CO2 generated corresponds to an increase of one OAA
B) 20 – every two molecules of CO2 generated corresponds to an increase of one OAA
C) 0 – two molecules of CO2 generated corresponds to one AcCoA used in the TCA; each AcCoA requires one molecule of OAA
D) 10 – one molecule of OAA is regenerated for every molecule of AcCoA used
Each cycle of TCA result in consumption of 1 Acetyl-Coenzyme (AcCoA) and 1 Oxaloacetate (OAA) molecule to give rise to 3 molecules of NADH and 2 molecules of CO2 per cycle. But at the end of each cycle, OAA molecule is regenerated. So the number of oxaloacetate(OAA) molecules remains unchanged.
Thus the correct option is option D which is 10 – 1 molecule of Oxaloacetate (OAA) is regenerated for every molecule of Acetyl-Coenzyme (AcCoA) used.
Siamese cats most of the time mate with Aegean cats, and the reason why is because Aegean cats are also domesticated and most of the times can easily be found.
Cells with cell chemicals and genetic material having no defined organelles and are all enclosed within a cell wall are called prokaryotes. Organisms in this group are small in size and are mainly bacteria. Ribosomes in these small cells are also small and ‘free floating’. DNA in prokaryotic cells is in the form of a circular strand and not as a chromosome.
Have an awesome day! :)
The ability to identify the specific location of skin touch in two different areas is communicated through sensory pathway .
<h3>What is sensory pathway?</h3>
The cerebral cortex or the cerebellum are the two destinations of the brain, and sensory pathways are the channels by which sensations or impulses travel from sense organs or receptors to the response centers there. While cerebellar impulses are important in coordination functions, cerebral cortex impulses enter through the thalamus and travel to the conscious portion of the brain.
Ascending and descending tracts make up the majority of the sensory pathways.
