Sunlight provides the energy to join the Carbon atoms together

C6H12O6 + 6O2 6CO2 + 6H2O Glucose contains stored energy from the sun.
7
of that energy in the bonds to be used later by heterotrophs
H2O + O2 CO2 Energy from the sun is what it took to build glucose and it retains a portion of that energy in the bonds to be used later by heterotrophs Glucose is stored C6H12O6 + 6O2 6CO2 + 6H2O Stored energy From the sun Photosynthesis
8
C6H12O6 Sugars are stored in fruits and to a lesser extent in
Vegetables (not sweet) and as starch in grains (not sweet)
9
Leafy vegetables and grasses don’t contain much if any simple
Sugars like glucose and no starch. Sugar is used to form cellulose which is not digestible by humans But Cows and Horses can digest it.

6CO2 + 6H2O C6H12O6 + 6O2
12
Apple trees are Autotrophs
They make their own food through photosynthesis Apples are full of glucose from photosynthesis
13
Glucose is consumed by a heterotroph
14
Glucose enters the blood supply and travels to a cell in the body.
15
6CO2 + 6H2O C6H12O6 + 6O2 Cellular Respiration
Glucose is used by heterotrophs for energy by breaking down the glucose molecule in the cell to release the energy stored in the bonds. Stored energy From the sun Cellular Respiration C6H12O6 + 6O2 6CO2 + 6H2O
17
6CO2 + 6H2O C6H12O6 + 6O2 When we breathe out, we exhale H2O and CO2
O2 enters the cell to help break down glucose O2 ATP H2O H2O ATP Glucose ends up as H2O and CO2 ATP CO2 CO2 H2O H2O CO2 Glucose is broken down by the cell to provide energy in the form of ATP. ATP is used to keep the cell alive, to drive all cell activities CO2 H2O ATP ATP H2O CO2 ATP CO2 ATP Cellular Respiration C6H12O6 + 6O2 6CO2 + 6H2O
