Study Notes
Photosynthesis Key Concepts
-
Light Reaction
Primary phase of photosynthesis that occurs in the thylakoid membranes, converting light energy into chemical energy in the form of ATP and NADPH. -
Sunlight
Essential energy source for photosynthesis; drives the light reactions and powers the formation of glucose. -
Thylakoid Membrane
Internal membrane system of chloroplasts where light reactions occur; contains chlorophyll and other pigments necessary for capturing light energy. -
Chloroplast
Organelles found in plant cells responsible for photosynthesis; contain thylakoids and stroma, playing a crucial role in converting light energy into chemical energy. -
H2O (Water)
Source of electrons in the light reactions and produces oxygen (O2) as a byproduct; essential for maintaining plant hydration and physiological functions. -
O2 (Oxygen)
Byproduct of the light reactions; released into the atmosphere and vital for aerobic organisms. -
CO2 (Carbon Dioxide)
Essential reactant in the Calvin Cycle used to synthesize glucose; absorbed from the atmosphere through plant stomata. -
Sugar
End product of photosynthesis; serves as an energy source and building block for various organic compounds in plants. -
Stroma
The fluid-filled space within the chloroplast surrounding thylakoids; location of the Calvin Cycle where CO2 is fixed into sugar. -
Calvin Cycle
Series of biochemical reactions occurring in the stroma that convert CO2 and energy from ATP and NADPH into glucose, essential for plant growth and metabolism.
