Unit 1 List 2 Cell Energy Flashcards
Autotroph
a being that can make its own food using light, water, carbon dioxide, or other chemicals
Light Reactions
the reaction of something to different intensities of the light
Chlorophyll
The green pigment in plants, algae, and cyanobacteria that is needed for photosynthesis
Photosynthesis
The process where plants transform light energy into chemical energy
Electron Transport Chain
four protein complexes that couple redox reactions, which makes an electrochemical gradient that leads to the creation of ATP
Calvin cycle
A cycle of chemical reactions where the carbon from the carbon cycle is made into sugars.
NADPH
It is an important electron donor that is used in a variety of biological settings
Pigment
It is an organic compound that gives plant or animal tissues color.
Granum
a stack of thylakoids in the chloroplasts of plant cells
Stomata
a pore that is surrounded by two guard cells which allows gas exchange
Heterotrophs
an organism that cant produce its own food
Carbon Fixation
It is the process when plants convert the carbon found in inorganic molecules in the atmosphere into organic matter to produce biological building blocks and fuel for cellular respiration.
Thylakoids
They are small compartments inside of chloroplasts.
Carotenoids
pigments that are found in plants, algae, and bacteria that are photosynthetic.
Mitochondrial matrix
the mitochondrion inside spaces encircled by the inner membrane.
