Chapter 11 – Energy Stress
Introduction
Normal cellular processes and functions are largely dependent on energy in the form of ATP. However, cells sometimes have too much ATP (energy excess) or too little ATP (energy limitation), which can result in energy stress. Energy stress can be induced by changes in a cell’s activity or environment. For example, frozen environments can be deprived of organic molecules or slow down enzyme function, reducing ATP production (Figure 11.1). This chapter on cell energy stress will outline the challenges associated with energy stress, the mechanisms used to detect energy stress and the strategies and mechanisms used to tolerate energy stress.
