Fat and ATP are different molecules that can both be described as molecules that store energy. Compare the functions of these molecules in terms of energy storage. (4 points) а ATP molecules are made when where there is an excess amount of energy, while fat molecules are used immediately. b ATP molecules are used for long-term storage, while fat is used for immediate energy. С Fat molecules are stable and can be stored for a long time, while ATP is not. d Fat molecules are unstable and can be stored short-term, while ATP molecules are stable and stored long term.
