BSC 108 Exam #2 (Kennedy)
Photosynthesis - ✅✅-Captures light energy from the sun and converts it to chemical energy
stored as glucose

✅✅-6CO2 + 6H2O ------> C6H12O6 + 6O2
Photosynthesis Equation -

Where does photosynthesis occur? - ✅✅-Chloroplasts

Stomata - ✅✅-Small, regulated pores in the leaf where carbon dioxide enters

Thylakoids - ✅✅-Where chlorophyll is located

Chlorophyll - ✅✅-Pigment whose function is to absorb solar energy, it is green because it
reflects green-yellow light

Stroma - ✅✅-Dense fluid surrounding the grana, contains enzymes
Light-Dependent Reactions - ✅✅-Uses the energy from sunlight to make the energy-storing
compounds ATP and NADPH

Steps of Light-Dependent Reactions - ✅✅ -1) Chlorophyll absorbs solar energy
2) Ejects an electron
3) Electron is passed down an electron transport chain
4) Water is split, releasing oxygen

Reactants of Light-Dependent Reactions -✅✅-Water, ADP, and NADP+
Products of Light-Dependent Reactions - ✅✅-Oxygen, ATP and NADH

Calvin Cycle - ✅✅-Uses the energy stored by the light-dependent reactions to make G3P,
which can be used to make glucose

Calvin Cycle Reactants -✅✅-ATP, NADPH, CO2, RuBP, Rubisco
Calvin Cycle Products - ✅✅-G3P - Used to make glucose

C4 photosynthesis - ✅✅-An adaptation of photosynthesis for hot and dry weather

Redox Reactions - ✅✅-A two-part reaction involving oxidation and reduction which always
occurs together.
Example: Rusting

Oxidation Reaction -✅✅-Involves the loss of electrons
Reduction Reaction - ✅✅-Involves the gain of electrons
