AP Biology Photosynthesis Quiz
Terms in this set (18)
*Why is it important for all non-plant life that plants photosynthesize at a faster rate than they go through cellular respiration?
Their wouldn't be enough oxygen and the plants wouldn't have enough to produce.
*Why photosynthesis is important to all living organism
*Animals often eat plants.
*Recycle the carbon dioxide we breathe out and turn it back into oxygen so that we never run out.
*What are the two stages of photosynthesis?
Light dependent reactions: Takes place in the thylakoid membrane and uses light energy to make ATP and NADPH
Calvin cycle(overview): When plants turn carbon dioxide from the air into sugar, the food autotrophs need to grow (energy and food)
*Chemical equation for photosynthesis
6CO2 + 6H2O ------> C6H12O6 + 6O2
*What is the name for the compound C6H12O6?
*Other than glucose, what other product is produced in photosynthesis?
Oxygen (released through plant leaves) and water (produced from oxygen atoms in co2 molecules)
*The organelle where light is absorbed in plants is called the ________?
*The primary absorption pigment of photosynthesis is ________?
*Why are plants leaves usually green?
*Why do leaves turn bright colors in the fall?
The plants shut down the full photosynthesis and the go dormant (chlorophyll breaks down and revealed the orangish colors)
Calvin Cycle reactions take place in the ________
*What are two big factors affecting the rate of photosynthesis?
*How might carbon dioxide levels affect the rate of photosynthesis?
Photosystems 1 & 2
*uses light energy to reduce NADP+ to NADPH+H+
*absorbs photons of wavelength
*provides high energy electrons (reduces NADP+ to produce NADPH)
*uses light energy to oxidize water molecules which produced electrons, protons, and O2
Product of light reactions
Product=ATP and NADPH
Autotrophs vs. Heterotrophs
Autotrophs can make their own food
Heterotrophs must obtain their food
The electrons lost in photosystem 1 is replaced by an electron from photosystem 11 and the electrons lost in photosystem 11 are replaced by electrons from a H2O molecule
Water's role in photosynthesis
*provides a source of H+, when it's split into H+ and O2 electrons are passed to PS II to replace the electrons that were excited by light (it's a reactant)
*releases O2 into the air
*provides electrons and hydrogen ions to power light dep/indep phases
