photosynthetic organisms capture energy from sunlight with pigments.
so without pigments light wouldnt be absorbed and photosynthesis couldnt happen
what role do pigments play in the process of photosynthesis?
it is a compound that can accept a pair of high energy electrons and transfer them, along with most of their energy, to another molecule
what are electron carrier molecules?
photosynthesis uses the energy of sunlight to convert water and carbon dioxide(reactants) into high energy sugars and oxygen(products)
basically the plant takes in water and carbon dioxide during photosynthesis and transforms it into sugars and oxygen
reactants= water and carbondioxide
products= high energy sugars and oxygyn
what are the reactants and products of photosynthesis?
light absorbing molecules used by plants to gather the suns energy
principle pigment of plants and other photosynthetic organisms
saclike photosynthetic membranes found in chloroplasts
fluid portion of the chloroplasts, outside of the thylakoids
NAPD+ (nicotinamide adenine dinucleotide phosphate)
one of the carrier molecules. this carrier molecule transfers high energy electrons from chlorophyl to other molecules
light independent reactions
a set of reactions in photosynthesis that do not require light. energy from ATP and NADPH is used to build high-energy compounds such as sugar. also called the calvin cycle
light dependent reactions
set of reactions in photosynthesis that use energy from sunlight to produce ATP and NADPH.
carbon dioxide(CO2) and water(H2O)
what are the reactants of photosynthesis?
chlorophyl molecules are located in the?
photosynthesis takes place inside organelles called?
have a lot of energy and require a carrier to be transported
the electrons carried by NADPH are similar to hot potato in that both what?
the leaf would lose its green color due to the breakdown of chlorophyl in the leaf
what would most likely happen to a healthy, green leaf that was covered with aluminum foil?
the light dependent reactions use energy from the sunlight to produce oxygen and convert ATP and NADP+ into the energy carriers ATP and NADPH.
what happens during the light dependent reactions?
during the light independent reactions, ATP and NADPH from the light dependent reactions are used to produce high energy sugars.
what happens during the light independent reactions?
among the most important factors that affect photosynthesis are....
2. light intensity
3. and the availability of water
what factors affect photosynthesis?
cluster of chlorophyll and proteins found in thylakoids
electron transport chain
series of electron carrier proteins that shuttle high energy electrons during ATP generating reactions.
cluster of proteins that span the cell membrane and allow hydrogen ions (H+) to pass through itn
light independent reactions of photosynthesis in which energy from ATP and NADPH is used to build high energy compounds such as sugar
photosystems contain pigments that absorb light and pass the energy on to what?
ATP and NADPH
the major products of light dependent reactions are what?
the calvin cycle
in photosynthesis, carbon dioxide is used to make sugars during what?
they provide the energy required to build high energy sugars
what is the function of NADPH and ATP in the Calvin cycle?
by sealing their leaves against water loss and trapping carbon as organic acids
how CAM plants photosynthesize under bright hot conditions without drying out?
ATP can easily release and store energy by breaking up and reforming the bonds between its phosphate groups. this characteristic of ATP makes it a basic energy source used by al types of cells.
why is ATP useful to cells?
in the process of photosynthesis, plants convert the energy of sunlight into chemical energy stored in the bonds of carbohydrates.
what happens during the process of photosynthesis?
compound used by cells to store and release energy
organism that obtains food by consuming other living things, also called a consumer.
in other words its an organism that cannot make their own food for energy so it consumes off of other organisms.
organism that is able to capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds, also called a producer.
this is an organism that can make its own food.
process used by plants and other autotrophs to capture light and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates such as sugars and starches.
it is made up of...
2. a 5 carbon sugar called ribose
3. and three phosphate groups
what does a adenosine triphosphate consist of?
a compound almost exactly like ATP, but has two phosphate groups instead and it takes in some energy not a lot like ATP.
using light to put something together
what is an easy thing to say what photosynthesis means?
ATP has three phosphates
ADP has two phosphates
what is the difference between ATP and ADP?
organisms that make their own food are called?
ATP to ADP
(the process of one phosphate leaving the ATP, causing only two phosphates to be left creating ADP)
energy is released upon the conversion of what?
carry out active transport
one way cells use the energy provided by ATP is to do what?
mushrooms eat by absorbing decomposing nutrients from organisms.
why are mushrooms considered heterotrophs?
