DDIE Describe how it is possible for a signaling molecule like adrenaline to be
released into the bloodstream to all the cells in the body and have 3 totally
different effects in different locations. In some cells it triggers an increase
in glycolysis. In others it triggers a decrease in glycolysis. Finally, there are
some cells in which the adrenaline causes no response at all. Explain how
this might be possible in terms of cellular communication and signal

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

weathering is the answer.

hybridization actually occurs frequently in nature. evolution is derived from the process of hybridization that creates things with different traits. this leads to the species changing and evolution occurring. hope this : )
