Unit 1 List 2 Cell Energy Flashcards
Autotroph
An organism that can produce its own food.
Light Reactions
Converts energy from the sun into chemical energy in the form of NADPH and ATP.
Chlorophyll
A pigment that gives plants their green color.
Photosynthesis
The process by which green plants transform light energy into chemical energy.
Calvin cycle
The cycle of chemical reactions where the carbon from the carbon cycle is fixed into sugars.
Electron Transport Chain
A series of four protein complexes that couple redox reactions.
NADPH
Nicotinamide adenine dinucleotide phosphate. An important electron donor.
Pigment
Any coloured material found in a plant or animal cell.
Granum
A stack of coin-shaped thylakoids in the chloroplasts of plant cells.
Stomata
Apore surrounded by two guard cells that allow gas exchange.
Carbon Fixation
The conversion of atmospheric carbon dioxide into organic molecules by autotrophic organisms.
Heterotrophs
An organism that eats other plants or animals for energy and nutrients.
Thylakoids
Tiny stack components found inside of chloroplasts.
Carotenoids
A group of naturally occurring pigments synthesized by plants, algae, and photosynthetic bacteria.
Mitochondrial matrix
The mitochondrion internal spaces enclosed by the inner membrane.
