Problem: Researchers have shown that ATP production can vary widely depending on cell conditions and how efficiently mitochondria work (Shen et al., 2024). Real cells are never perfect, some energy is lost as heat, and some is used to move materials in and out of the mitochondria. These extra steps reduce the amount of ATP produced. Different cell types and stresses, such as infection or illness, can also change how efficiently ATP is made. - Comment. Need Assignment Help?
