Lesson Overview Energy and Life Lesson Overview 8.1 Energy and Life Lesson Overview Energy and Life THINK ABOUT IT Homeostasis is hard work. Organisms and the cells within them have to grow and develop, move materials around, build new molecules, and respond to environmental changes. What powers so much activity, and where does that power come from? Lesson Overview Lesson Overview Energy and Life Chemical Energy and ATP Energy is the ability to do work. Your cells are busy using energy to build new molecules, contract muscles, and carry out active transport. Without the ability to obtain and use energy, life would cease to exist. Lesson Overview Lesson Overview Energy and Life Chemical Energy and ATP One of the most important compounds that cells use to store and release energy is adenosine triphosphate (ATP). ATP consists of adenine, a 5-carbon sugar called ribose, and three phosphate groups. Lesson Overview Energy and Life Energy and Life Storing Energy Adenosine diphosphate (ADP) looks almost like ATP, except that it has two phosphate groups instead of three. ADP contains some energy, but not as much as ATP.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
