Description
Abstract
The development of some enzymes and enzyme systems necessary for energy metabolism in the hearts of developing chicken embryos was studied from day 7 through day 12. There was a 36% decrease in the protein present per g of wet tissue weight during this time period. A 242% increase in ETS activity per g of tissue and a 436% increase per mg of protein present was found. LDH activity was found to decrease 64% relative to mass and 44% relative to protein content. The overall glucose utilization decreased 83% when related to the mass of the hearts and 89% when related to the protein content. Thus, there was an increase in the dependence on the enzyme systems which require oxygen and are more efficient. There was also a decrease in the activity of the enzyme systems which do not require oxygen.
