SENESCENCE  Every autumn plants changes their colour, after that the loss of leaves can be seen  from deciduous trees. The reason behind this is , because of change in  day length and cooling temperature which triggers developmental process that lead to leaf senescence and death. Senescence and necrosis are two different processes,  although both of them  lead to death of the cells. Necrosis is death brought out by physical...

GLYCOLYSIS

Glycolysis Glycolysis  derives its name  from the Greek words "glycos"- sugar and "lysis" - splitting. In this process , Glucose  is converted into two molecules of Pyruvate or pyruvic acid, an organic acid. Apart from preparing substrate for Citric acid cycle, the other function of this is to yield chemical energy in the form of ATP and NADH.
