Liv Env: Photosynthesis Study Exam
Questions With Correct Answers
What is photosynthesis? - answer✔This process stores energy from sunlight in the chemical
bonds of glucose
What is the equation for photosynthesis? - answer✔6CO2 + 6H2O -----> C6H12O6 + 6O2
Where are the pigments in the chloroplast stored? - answer✔thylakoids
What is the ultimate goal of photosynthesis? - answer✔to make simple sugars like glucose
what are the three stages of photosynthesis? - answer✔1- Capture Light Energy
2- Light Dependent Reaction
3- Calvin Cycle
what is the first stage of photosynthesis? ( capture light energy) - answer✔- starts in pigment
stored in thylakoids of chloroplasts.
-Light excites electrons in the pigment molecule. This
jumpstarts stage 2
what is the second stage of photosynthesis? (light dependent reaction) - answer✔- Water is split
to form oxygen gas & hydrogen ions(H+ )
-These hydrogen ions are then used in TWO separate
mini electron transport chains.
why are hydrogen ions used in two separate mini electron transport chains? - answer✔1. to
make just a little ATP to power the next cycle
2. to make a low energy molecule (NADPH)
what is the third stage of photosynthesis? (Calvin cycle) - answer✔Using the ATP and
NADPH, the carbon from CO2 is attached to a precursor ribulose (a 5 carbon sugar) to make
glucose, a six carbon sugar (C6H12O6).
What is the reason for pigment? - answer✔to trap light
