Unit 3 Flashcards
Photosynthesis
The process that captures energy from sunlight to make sugars that store chemical energy.
Chlorophyll
A molecule in chloroplasts that absorb some of the energy in visible light.
Thylakoid
Stacks of coin-shaped membrane-enclosed compartments called grana.
Light-dependent reaction
Captures energy from sunlight.
Light-independent reaction
Uses energy from light-dependent reaction to make sugars.
Photosystem
Light energy is captured and transferred in the thylakoid membranes by two groups of molecules.
Electron Transport Chain
A series of proteins in the membrane of the thylakoid.
ATP Synthase
The protein channel that creates ATP.
Calvin Cycle
Makes simple sugars.
Cellular Respiration
Releases chemical energy from sugars and other carbon-based molecules to make ATP when oxygen is present.
Aerobic
Where oxygen is used to make ATP, H2O, and CO2.
Glycolysis
Splits glucose into two pyruvate and makes some ATP.
Anaerobic
Does not need oxygen.
Krebs Cycle
Produces molecules that carry energy to the second part of cellular respiration.
CO2 + H2O –> C6H12O6 + O2
