bio ch 8 Flashcards
whats a autotrophs
organsims that use sun to make food
what are heterotrophs
eat things for food
why is atp called that
becuase it has three phosphates
are the bonds between the AtP phosphates low or high
Very high energy
what will the adp do if it needs more energy in a energy crisis
it turns into AMP
what happenes when atp loses a phosphate group
It turns into ADP
when a phosphate breaks off what going to be released
a little packet of energy
Describe ATP-ADP cycle
adp gets charged back up on atp
how come gamma and xrays dont reach us and arent a problem
because fo the atmoshphere and ozone layer for uv lights
IN the parts of the chloplast whats the coin like thing called?
are they hollow or solid
whats a stack of thylakoid called
what are the empty spots in chlorplasts
thylakoid
hollow
granum
stroma
which colors have the most photosythesis
blue and red
what happens when you shine light through a prism
you can see all the colors of the rainbow
what did the greenish yellow filter do to the light?
?what colors dissapeared acronym
reflected green and yellow
robiv blue and red
explain the whole light reaction
why are there accessory pigiments
like red
to absorb light at different wavelengths and increase the amount of energy they can capture from sunlight:
explain the whole dark reaction
where does the light reaction occur in the chloroplast
the thylakoid membrane of the chloroplasts
What is the structure of ATP
had adenine (nitrogenous base) a ribose (5c sugar) and 3 phosphate groups attached together with high energy bonds
what does ATP do
its like electricity that provides energy for the cell
what are the stages of photosynthesis
the light-dependent reactions (light reactions), where light energy is captured and converted into chemical energy, and the Calvin cycle (dark reactions)
what is the main source of energy that supports life on earth
the sun
why is atp called the energy currency of the cell
becuase it powers a lot of cellular molecules.
How is the enrgy in ATP released
when one of its phosphate groups is removed through a process called hydrolysis
what are some examples of cellular processes that require atp for energy
