Double Bubble: Photosynthesis
Directions: Using the phrases below, organize them in to a double bubble comparing respiration and
photosynthesis.
Two ATP are produced during
anaerobic glycolysis
ATP is synthesized
Light energy is changed to chemical
energy
Oxygen is released as a by-product
Usable chemical energy is produced
Light, chlorophyll, water, and carbon
dioxide are raw materials and
energy source
Energy is released when the
chemical bond to the third
phosphate in ATP is broken
Occurs in mitochondria of all
eukaryotic cells
Water is split during photolysis to
harvest hydrogen for the light
independent reactions
Proteins in the electron transport chain
pass energized electrons along during
the formation of ATP
Electron carrier molecules are used
C6H12O6 + 6 O2  36 ATP + 6 CO2 +
6H2O
Requires carbon dioxide
Energy is used to bond phosphate
to ADP
Requires oxygen
Light energy is trapped by a pigment
called chlorophyll a
In the Calvin cycle a series of reactions
use CO2 to form carbohydrates
Occurs in chloroplasts of some
eukaryotic cells
Glucose is split into two pyruvic
acid molecules during glycolysis
CO2 is released during the kreb’s cycle
Glucose is split into two pyruvic
acid molecules during glycolysis
6 CO2 + 12 H2O  C6H12O6 + 6 O2 + 6 H2O
Glucose and oxygen are raw
materials
Water is released as a by-product
ATP is the molecule that stores
energy for biological work in cells
The kreb’s cycle and the electron
transport chain produce ATP in the
mitochondria
Potential energy is stored in the
chemical bonds of the molecules of the
reactants and products
