-energy
●● What does Adenosine Triphosphate (ATP) do?
Answer: provides energy in a form that all cells can readily use to
perform the work of the cell

●● What are the two types of metabolism?
Answer: -catabolism
,-anabolism
●● Does catabolism produce or require ATP?
Answer: produces

Answer: structure or position is changed
●● Chemical energy is a form of what type of energy?
Answer: potential
●● Strong bonds have ________ potential energy than weak bonds.
Answer: less
●● Why are phosphate bonds so weak?
Answer: the negatively charged oxygens repel one another
●● What is the first law of thermodynamics?
Answer: energy is neither created nor destroyed, it simply changes from
one form to another
