Effects of pH, heat shock and nutrients starvation on metabolic reactions

Solutions

Expert Solution

temprature;-

upto a part rate of enzymatic reaction increase with increasing temperature, because substrate collide with active site mole frequently whwn molecules move rapidly .above that temperature speed of enzymatic reaction drops sharply.

in human the optimal temperature is 35-40℃

example of this kind of reaction like thermophilic becateria which can easily perform great in higher temperature.

diagramtically:-

2. PH;-

just as an enzymes has optimal temperature it also has a PH At which is most active.

optimal pH range is 6-8 which is near to neutral.

but there are exception like pepsin whicj perform in low acidic environment is PH 2.

diagramatically:-

nutrient starvation:-

the ability to maintain a metabolic capacity when a nutrients and/ or energy source was abruptly removed from.cells was critically dependent on starvation condition.

nitrogen starvation was much more determinal in this respect than carbon starvation.
