Practice question

UCP1 (C) is the right choice. This sits at the heart of Thermoregulation: the wording points straight to what is happening in the tissue or organ system. A useful study habit is to ask what the structure or process is for: UCP1 is the option that correctly names the structure, process, or principle asked for in Thermoregulation. That reasoning supports UCP1. One solid sentence about why this works is enough for recall — you do not need a long essay for every MCQ. When you practise, cover the choices first, write UCP1 from memory, then reveal the letter — that habit builds real recall for Thermoregulation.
