|
|
heterotrophs
|
organisms that obtain energy from the foods that they eat.
|
|
|
what is PGAL?
|
when PGA is energized to form this
|
|

where in the chloroplast does electron transport take place?
|
photosynthetic membrane
|
|
|
photostems
|
clusters of pigment molecules
|
|
|
what takes place in the middle of the photsynthetic chain?
|
hydrogen ions are being pumped across the membrane
|
|
|
which product in the basic equation for photsynthesis is obtained directly from water?
|
oxygen
|
|
|
what did ingenhousz do to help the understanding of photosyntesis?
|
Light is neccessary for plants to produce oxygen.
|
|
|
what are the requirements for photosynthesis?
|
light absortion, electron transport, oxygen production, and Atp formation
|
|
|
what is the balanced equation for photosynthesis?
|
6CO + H O Light-->C H O + 6O
|
|
|
what is the dark cylce, or Calvins cycle?
|
carbon dioxide is used to make a complex molecule. this molecule is a building block used to make other molecules like glucose.
|
|
|
what are the products of photosynthesis?
|
glucose and oxygen
|
|
|
how many hydrongen ions are produced each time in photolysis?
|
4
|
|
|
chlorophyll
|
the principal pigment of green plants.
|
|
|
what is electron transport?
|
when high-energy electrons are passed from one electron carrier to the next. as they are being passed, a little bit of energy is being lost each time
|
|
|
autotrophs
|
organisms that are able to use a source of energy, like light, to produce food directly from simple inorganic molecules.
|
|
|
what is PGA?
|
when an unstable 6 carbon molecule instantly splits into two 3 carbon molecules
|
|
|
what did priestly do to contribute to photosynthesis?
|
he noticed that plants release oxygen.
|
|
|
what other substance is obtained from water during the light reaction?
|
hydrogen ions and oxygen
|
|
|
what are the requirements of photosynthesis?
|
carbon dioxide, water, light, chlorophyll
|
|
|
hich reactant in the basic equation for photsynthesis is used in the light reaction?
|
water
|
|
|
What did van helmont do to contribute to photosynthesis?
|
that carbon dioxide in the air made a major contribution to the mass of trees.
|
|
|
what is produced in the light-dependent reaction of photosynthesis?
|
ATP,NADPH, oxygen
|
|
|
What is photosynthesis?
|
the process of photosynthesis is when plants covert the energy of sunlight into the energy in the chemical bonds of carbohydrates- sugars and starches.
|
|
|
what are the energy storing comounds created by photosynthesis?
|
ATP, NADPH
|
|
|
what else is being added to NADP+ besides 2 electrons?
|
hydrogen ions
|
|
|
what is the energy souce from the basic process of photosynthesis?
|
sunlight
|
|
|
where does the energy come from to split water molecules?
|
sunlight
|
|
|
why is chlorophyll essential to photsynthesis?
|
it absorbs the most amount of sunlight
|
|
|
how many water molecules are split at one time?
|
2
|
|
|
what is PGA?
|
when an unstable 6 carbon molecule instantly splits into two 3 carbon molecules
|
|
|
pigments
|
colored substances that absorb or reflect light.
