Sparks-ch 4 Vocab

Vocab chapter 4 for bio 1 period 2

ATP molecule that transfers energy from the breakdown of food molecules to cell processes
ADP lower-energy molecule that can be converted into ATP by the addition of a phosphate group
chemosynthesis a process by which some organisms use chemical energy instead of light energy to make energy-storing carbon-based molecules
photosynthesis process that captures energy from sunlight to make sugars that store chemical energy
chlorophyll molecule in chloroplasts that absorbs some energy in visible light
thylakoids stacks of coin-shaped, membrane-enclosed compartments
light-dependent reactions capture energy from sunlight; sunlight is needed
light-independent reactions use energy from the light-dependent reactions to make sugars; sunlight is not needed
cellular respiration released chemical energy from sugars and other carbon-based molecules to make ATP when oxygen is present
aerobic needs oxygen to take place
glycolysis splits glucose into two three-carbon molecules and makes two molecules of ATP
anaerobic does not need oxygen to take place
Krebs cycle produces molecules that carry energy to the second part of cellular respiration
fermentation does not make ATP, but it allows glycolysis to continue
lactic acid C3H6O3 is what causes your muscles to "burn" during hard exercise
