2715659984Autotrophan organism that is able to capture energy from the environment and store it in the chemical bonds of organic molecules0
2715660883Heterotrophan organism that must acquire energy by consuming other organisms1
2715660884Photosynthesisthe chemical reaction that captures energy from sunlight and stores it in the chemical bonds of organic molecules2
2715661290Chemosynthesisthe chemical reaction that captures energy from environmental chemicals and stores it in the chemical bonds of organic molecules3
2715661535Adenosine triphosphate (ATP)the energy-carrier molecule used to power cellular processes; stores energy in the chemical bonds between its three phosphate groups4
2715662188Adenosine diphosphate (ADP)the energy-carrier molecule used to power cellular processes; stores energy in the chemical bonds between its two phosphate groups5
2715665106Cellular respirationthe chemical reaction used by living cells to release energy from organic molecules6

2715684857Thylakoidsthe interconnected disk-shaped pouches in chloroplast8
2715685165Granuma group of thylakoids9
2715685166Light-dependent reactionsthe phase of photosynthesis in which sunlight is converted to chemical energy and oxygen is released10
2715685973Light-independent reactionsthe phase of photosynthesis in which a three-carbon sugar is formed11
2715685974Photosystem IIthe phase of light-dependent reaction in which sunlight energy excites electrons and an enzyme splits water into hydrogen ions, oxygen molecules, and free electrons12
2715686760Electron transport chaina series of molecules within the thylakoid that moves energized electrons from photosystem II to photosystem I13
2715686761Photosystem Ithe phase of light-dependent reaction in which the energy carrier NADP+ is reduced to NADPH14
