chemical/molecules
In chemosynthesis, ____ energy is used to produce carbon-based ____ that store energy.
waste product/muscles
Lactic acid is the three-carbon ____ of lactic acid fermentation. It causes a burning feeling in your ____ during exercise.
grana
Thylakoids are coin-shaped, membrane-enclosed compartments inside the ____.
phosphate group
ADP is converted back into ATP by the addition of a ____.
light energy/chemical energy
Photosynthesis captures ____ to make sugars that store ____.
grana/stroma
Photosynthesis takes place in two parts of a chloroplast: the ____ and the ____.
Alcoholic Fermentation
Produces alcohol and carbon dioxide
Lactic Acid Fermentation
Produces lactic acid
Lactic Acid Fermentation and Alcoholic Fermentation
Recycles NAD+ to glycolysis
chemical energy
Some organisms are called producers because they produce the source of ____ for themselves and for other organisms.
Two ways in which cellular respiration seems to be opposite of photosynthesis
1. The overall chemical equations are the reverse of each other. 2. Cellular respiration breaks down sugars to make ATP, and photosynthesis uses ATP to make sugars.
Photosynthesis equation
6CO2 + 6H2O ---> C6H12O6 + 6O2
three/two
ATP has ____ phosphate groups, and ADP has ____ phosphate groups.
high-energy/lower-energy
ATP is a ____ molecule that is converted into ____ ADP when a phosphate group is removed and energy is released.
molecule/food molecules
All cells use adenosine triphosphate (ATP) for energy. ATP is a _____ that transfers energy from the breakdown of _____ to cell processes.
Chemical equation for cellular respiration
C6H12O6 + 6O2 ----> 6CO2 + 6H2O
energy/oxygen
Cellular respiration is a process that releases ____ from sugars and other carbon-based molecules to make ATP when ____ is present.
oxygen
Cellular respiration is called an aerobic process, because it needs ____ to take place.
mitochondria
Cellular respiration takes place in the ____.
chemical energy/light energy
Chemosynthesis is a process by which some organisms use ____ instead of _____ to make energy-storing carbon-based molecules.
visible light
Chlorophyll is a molecule in chloroplasts that absorbs some of the energy in ____.
green
Chlorophyll is the light-absorbing molecule that makes leaves look ____.
photosynthesis
Chloroplasts are membrane-bound organelles where ____ takes place in plants.
sugar
During glycolysis, a ____ is broken down (or "loosened").
glucose/ATP
During glycolysis, one molecule of ____ is split into two three-carbon molecules and two ____ are formed.
energy/sugars
During photosynthesis, ____ from light is used to put together ____.

independent
The reactions in photosynthesis that do not require light are called light-____.
carbon dioxide
The term fermentation is based on a word that means "to bubble." This meaning is related to the fermentation process because bubbles of ____ are produced during alcoholic fermentation.
