What is the high energy molecule formed at the end of cellular respiration called?
A.
ADP
B.
ATP
C.
NAD

Explanation:

ADP (Adenosine diphosphate) is a starting material in respiration. Through the process of respiration a 3rd phosphate is added to the compound to make it ATP (Adenosine Triphosphate). This extra phosphate in the end product is what allows the cell to use the compound for energy.

NAD and NADH are used in the electron transport chain but not going to be the energy molecule

Answer A is WRONG, CORRECT answer is B. ATP

Explanation:

The high energy molecule formed at the end of cellular respiration is B. ATP.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
