Cellular Energy and Organic Molecules Review Flashcards
heterotroph
animals, most bacteria, fungi
ATP
energy transfer molecule
autotroph
plants, algae, some bacteria that make their own food
photosynthesis
the process in which autotrophs convert light energy into chemical energy
where does the energy for all organisms ultimately come from?
sun
how many phosphates does ATP have? where’s the energy stored in ATP?
3, energy is stored in the bonds between phosphates
where does photosynthesis take place in bacteria (prokaryotes)?
cell membrane
where does photosynthesis take place in plants or algae (eukaryotes)?
chloroplasts
other than raw materials, what else is required for photosynthesis?
sunlight
light cycle
- chlorophyll in chloroplasts captures light
- light is used to split water into hydrogen and oxygen
- hydrogen is used in calvin cycle and oxygen is expelled as waste
- small amount of ATP is made and used in calvin cycle
calvin cycle
- carbon dioxide from air and products from light cycle are combined to make glucose
- glucose can be used to make plant structures and provide energy for plant
what 3 things are made in the light cycle and used in the calvin cycle?
chemical bonds, ATP, NADPH
photosynthesis equation (raw materials, waste product, main product)
6CO2 + 6H2O = C6H12O6 + 6O2
raw materials = main product + waste product
carbon dioxide + water = glucose + oxygen
where does the carbon come from that’s used to build glucose during photosynthesis?
carbon dioxide
where does the hydrogen come from that’s used to build glucose during photosynthesis?
water molecule
