12 . ATP is the molecule that is used to provide energy necessary to power cellular functions , and as a result , it is often called the “ energy currency ” in the cell . How might this “ energy currency ” be saved ; meaning , what organic molecule can be produced and later used to provide ATP ? And what organic molecule might be considered the paycheck ; the molecule that is “ cashed ” in order to get ATP quickly ? Explain both your answers .
13 . With the massive amount of plant life , ample rainfall and favorable temperatures , you might think that tropical rainforests would be large net producers of oxygen , and yet surprisingly , they are not ! With your knowledge of photosynthesis and cellular respiration , can you explain why this might be true ? Think about what happens when a leaf drops or fruit from a tree is eaten .
