Adenosine Triphosphate (ATP)
|
Compound used by cells to store and release energy
|
|
Heterotroph
|
Organism that obtain food by consuming other living things; also called a consumer
|
|
Autotroph
|
Organism that is able to capture energy from sunlight or chemicals ans use it to produce its own food from organic compounds; also called a producer.
|
|
Photosynthesis
|
Process used by plants and other autotrophs to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates such as sugars and starches.
|
|
Pigment
|
Light-absorbing molecules used by plants to gather the sun's energy
|
|
Thylakoid
|
Saclike photosynthetic membranes found in chloroplasts
|
|
Chlorophyll
|
Principal pigment of plants and other photosynthetic organisms
|
|
Thylakoid
|
Saclike photosynthetic membranes found in chloroplasts
|
|
Stroma
|
Fluid portion of the chloroplasts; outside of the thylakoids.
|
|
NADP+
|
(nicotinamide adenine dinucleotide phosphate) carrier molecule that transfers high-energy electrons from chlorophyll to other molecules
|
|
Light-Dependent reactions
|
Set of reactions in photosynthesis that uses energy from light to produce ATP and NADPH
|
|
Light-Independent Reaction
|
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
|
|
Photosystem
|
Cluster of chlorophyll and proteins found in thylakoid
|
|
Electron transport chain
|
Series of electrons carrier proteins that shuttle high-energy electrons during ATP- generating reactions
|
|
ATP Synthase
|
Cluster of proteins that spin the thylakoid membrane and allow hydrogen ions (H+) to pass through it.
|
|
Calvin Cycle
|
The light-independent reaction of photosynthesis in which energy from ATP and NADPH is used to build high energy compounds such as sugars
