Question
To remove a potential toxin from the body requires the use of an energy consumptive process. At the cellular level this process relies on the following steps: a) absorption from the bloodstream of toxin; b) intracellular acquisition of toxin by an active transport mechanism; c) dephosphorylation of the toxin by an enzyme controlled system; d) intracellular removal of harmless end products by exocytosis. Please answer completely the following questions by referencing the narrative above. . Which lettered activity did not require energy and why? (5 points) . Name all the organelles and the functions required of them for c and d to take place.( If the cell had mitochondrial deficits, which lettered activity would be compromised?Explanation / Answer
The last step of intracellular removal of by products does not require energy because it is done by the vesicle fusion to the cell membrane. Microtubules are protein wich mskes a track for the transport of vescivle to the cell membrane.
2. These both reaction occurs in the vescicle which contains enzymes.
Vescicle have lot of enzymes for various activities sometime lysosome cell orgenel act on the toxin and hydrolyze it. After the break down it moves to the normal vescicle which csrries the content and transport out of the cell membrane.
3. in the mitrochondrial affected cell ATP production is highly affected. Mitochondria is called as Power house of the cell because ATP production occurs in it. So this reaction was affected.
Mitochondria is a site of aerobic respiration krebs cycle and ETS
