    Normal function is sugar to ATP, then the mitochondria use ATP. In humans it’s only broken ATP that uses sugar directly

      Your first sentence is wrong (the mitochondria’s primary function is to generate ATP, which then gets transported to elsewhere where its stored energy is used). And your second sentence is confusing. With “broken ATP” you mean ADP? Or broken ATP synthesis? The point of this alternative oxidase pathway is producing some ATP, but inefficiently. And it produces also heat, because of its inefficiency (not all the energy stored in the sugars can be turned into chemically stored energy so it also produces heat energy. Think traditional light bulb). This heat is then used in the inflorescences of some aroids.

        Yeah it’s outside my expertise so I’m bad at the detail.

        Normal process is the nice efficient anaerobic process that produces ATP from glucose

        Cancers use an all aerobic process which is less efficient but faster at producing ATP
