thinking in terms of mass, thinking in terms of energy/photosynthesis Flashcards
(25 cards)
can energy be converted into mass?
Yes a lot of energy must be present in order to do so.
can mass turn into energy?
yes one way through nuclear fission
what is transforming sunlight energy into chemical energy?
photosynthesis
what is anabolism vs catabolism
anabolism is the building of a complex structure while catabolism is the breaking down of complex structure
what can perform photosynthesis?
plants, algae, some micro-organism
in what organelle does photosynthesis occur?
chloroplast
how does photosynthesis happen
plants take in sun, co2 and h2o
What is chlorophylls purpose
absorbs sunlight
What is the role of sunlight in
photosynthesis? carbon dioxide? water? glucose?
sunlight causes a chemical reaction breaking down co2 and h2o to make glucose(sugar)
in photosynthesis what is the meaning of “food”
what provides an organism energy
why is photosynthesis anabolic?
forms glucose by combining water and carbon dioxide
how is carbon dioxide turned into glucose
in the process of photosynthesis
” What two molecular processes, that together make-up photosynthetic
metabolism, transform light energy into chemical energy?
light reactions, calvin cycle
where do photosynthetic processes take place?
chloroplasts
what happens during the Calvin cycle
uses energy from ATP to produce sugars for plants
? During which process is oxygen gas
released and why?
photosynsthesis, and it can be a waste product and helps the atmosphere overall
During which process are carbon dioxide molecules put together or
“fixed” into sugar molecules?
Calvin Cycle
What is the role of NADPH and ATP in photosynthesis?
helps provide energy and reducing power for photosynthesize
Where do the hydrogen atoms in a molecule of glucose produced during photosynthesis
come from?
water
Where do the oxygen atoms in a molecule of glucose come from?
carbon dioxide
Where do
the carbon atoms in a molecule of glucose come from?
carbon dioxide
how does cellular respiration happen?
goes through processes and aids in producing energy
where does cellular respiration take place?
Takes place in the mitochondria or cytoplasm
is cellular respiration the same as photosynthesis?
not exactly, both are process that take place in living organisms but humans don’t go through phot
