Cells must efficiently transfer energy from their energy trapping system to the systems actually carrying
out work and also use various metabolic processes to replace the energy used in doing work. This is
called the_____ - Answer energy cycle
In order for the cell to be able to input energy into necessary endergonic reactions, energy generating
processes such as photosynthesis, fermentation, and respiration are used to produce_____ - Answer
ATP
Disruption of an enzymes structure with loss of activity caused by extremes of pH, temperature, or other
factors is called____ - Answer Denaturation
