Overall:
Plants use
photosynthesis
Animals break down
food
to make
to produce
Glucose
That’s used Which cells use as
to make
the main form of
ATP
Energy
Energy is stored in chemical bonds, when you break the bond energy is released
Glucose likes to “break down” and releases a lot of energy when it does.
That energy is used to make ATP
Exergonic Reaction- Gives off energy
Endergonic Reaction- absorbs or stores energy
Photosynthesis
producers
Where, in the cell, does photosynthesis take place?
Chloroplast
The goal of photosynthesis is to produce what? Glucose
Takes place only in
autotrophs
also known as
Use words to correctly write out the process of photosynthesis, in the space below.
Carbon Dioxide + Light + Water  Glucose + Oxygen +Water
Use formulas (and light) to correctly write out the photosynthesis equation in the space below.
6CO2 + Light + 12H2O  C6H12O6 + 6O2 +
Is an
6H2O
Endergonic Reaction because it absorbs the energy from the sun and stores it in glucose.
Cellular Respiration
producers(autotrophs) and consumers(heterotrophs)
Where, in the cell, does cellular respiration take place? Mitochondria
The goal of cellular respiration is to produce what?
Energy (ATP)
Takes place in both
Use words to correctly write out the process of cellular respiration, in the space below.
Glucose + Oxygen
 Water + Carbon Dioxide + Energy
Use formulas (and ATP) to correctly write out the cellular respiration equation in the space below.
C6H12O6 + O2  6H2O + 6CO2 + 38ATP
Is an Exergonic Reaction because it releases the energy stored in glucose to produce ATP.
Fermentation
Takes place in both
producers(autotrophs)
Where, in the cell, does fermentation take place?
and
consumers(heterotrophs)
Cytoplasm
Energy (ATP)
The goal of fermentation is to produce what?
Fermentation in Muscle Cells
One big drawback of fermentation (in muscle cells) is that in an additional reaction it also produces what?
Lactic Acid
Use words to correctly write out the process of fermentation, in the space below.
Glucose  Lactic Acid + Energy
Use formulas (and ATP) to correctly write out the fermentation equation in the space below.
C6H12O6  2C3H6O3 + 2ATP
Fermentation in Bacteria & Yeast Cells
Ethanol
Instead of producing lactic acid, anaerobic respiration in bacteria and yeast cells produces ATP and
Use the following words to correctly write out the process of fermentation, in the space below.
Glucose  Carbon Dioxide + Ethanol + Energy
Use the following formulas to correctly write out the fermentation equation in the space below.
C6H12O6  2CO2 + 2C2H6O + 2ATP
