- why is rubisco important?
- it is the most important enzyme in nature
- 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
- pigments
- colored substances that absorb or reflect light.
