Animal Cell Culture and Regulation What is the effect of excess accumulation of metabolite products (lactate and ammonium) on cells? They act as growth inhibitors They act as growth promoters Have no effect on cells Lactate helps in the growth while ammonium inhibits the growth They act as growth inhibitors They act as growth promoters Have no effect on cells Lactate helps in the growth while ammonium inhibits the growth ANSWER DOWNLOAD EXAMIANS APP

Animal Cell Culture and Regulation During the growth of animal cells in culture, it is noticed that the cells do not look very healthy. After an investigation, this is found that there is a lot of lactic acid in the culture fluid. What is probably wrong with this culture? Ethyl alcohol is being produced in excess The cells do not have enough oxygen Glycolysis is being inhibited The cells have too much oxygen Ethyl alcohol is being produced in excess The cells do not have enough oxygen Glycolysis is being inhibited The cells have too much oxygen ANSWER DOWNLOAD EXAMIANS APP
Animal Cell Culture and Regulation Sometimes cell lines can be cultured for such a long time that they apparently develop the potential to be subcultured indefinitely in vitro. Such cells lines are called propagated cell lines primary cell lines established cell lines secondary cell lines propagated cell lines primary cell lines established cell lines secondary cell lines ANSWER DOWNLOAD EXAMIANS APP
