Chapter 6 I. energy- 1. is the capacity to do work. Ex light, electricity, heat, motion 2. energy can be neither created nor destroyed. It can only change forms/ 3. energy disperses 4. energy flows in one direction 5. energy can change forms. Light → chemical energy most is lost as “heat” II. Chemical bonds 1. Atoms join to form molecules 2. chemical reaction Reactants → products 3. chemical bonds hold energy endergonic vs exergonic reactions endergonic: energy in. 2H20 → 2H2+O2

Unformatted text preview: *photosynthesis=endergonic *cellular respiration=exergonic 4. activation energy: minimum amount of energy needed to start a chemical reaction. *energy can come from ATP from a cell. *ATP= cells energy current 5. ATP, the cells energy currency accepts energy from exergonic reactions.-gives energy to endergonic reactions.-gives energy by giving phosphate groups away.-enzymes also gets a reaction going....

    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.
