Study Notes
Photosynthesis Vocabulary
-
Adenosine triphosphate (ATP)
- Energy-storing compound used by cells for various functions
-
ATP synthase
- Protein complex that facilitates the passage of hydrogen ions (H+) through the cell membrane, critical for ATP production
-
Autotroph
- Organisms that produce their own food from sunlight or chemicals, classified as producers within ecological systems
-
Calvin cycle
- Refers to light-independent reactions where carbohydrates are synthesized from atmospheric carbon dioxide
-
Chlorophyll
- The primary pigment in plants and photosynthetic organisms, essential for capturing light energy
-
Electron transport chain
- A sequence of proteins involved in transferring high-energy electrons, essential for ATP synthesis during cellular respiration
-
Heterotroph
- Organisms that acquire energy by consuming other organisms, known as consumers in food webs
-
Light-dependent reactions
- Reactions that capture sunlight to produce oxygen, converting ADP and NADP+ into energy carriers ATP and NADPH
-
Light-independent reactions
- Reactions that do not utilize light directly; they utilize ATP and NADPH to form glucose and other high-energy compounds
-
NADP+
- A carrier molecule that transports high-energy electrons from chlorophyll to various biochemical pathways
-
Pigment
- Molecules that absorb light, enabling plants to capture solar energy for photosynthesis
-
Photosynthesis
- Process by which autotrophs like plants convert light energy into chemical energy, transforming carbon dioxide and water into oxygen and carbohydrates
-
Photosystem
- Complex of chlorophyll and proteins found in thylakoids, crucial for the initial stages of light-dependent reactions
-
Stroma
- The fluid matrix surrounding thylakoids in chloroplasts, site of light-independent reactions
-
Thylakoid
- Membrane structures within chloroplasts that house the machinery for photosynthesis, specifically light-dependent reactions
