The ADP-ATP cycle is critical to producing cell energy. What do you know about this cycle?

ADP-ATP cycle is energy producing cycle in which energy is produced by converting Adenine tri phosphate (ATP) into Adenine di phosphate (ADP). When energy is needed to cells, the cell convert the available ATP into ADP and phosphate. The energy is released from decomposing phosphate molecule. After that, ADP is again converted into ATP by mitochondria using food molecules.

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
