Photosynthesis Vocab - CORE Acc. Biology 9

(i have an anki deck for this... lmk if u want it)

Photosynthesis

process by which light energy is converted to chemical energy; produces sugar and oxygen from carbon dioxide and water

Chlorophyll

light-absorbing pigment molecule in photosynthetic organisms

Light-dependent reactions

part of photosynthesis that absorbs energy from sunlight and transfers energy to the light-independent reactions

Light-independent reactions (Calvin Cycle)

part of photosynthesis that uses energy absorbed during the light-dependent reactions to synthesize simple sugars/carbohydrates (glucose) from CO

Electron Transport Chain

series of proteins in the thylakoid and mitochondrial membranes that aid in converting ADP to ATP by transferring electrons

thylakoid

membrane-bound structure within chloroplasts that contains chlorophyll and other light-absorbing pigments used in the light-dependent reactions of photosynthesis

photosystem

series of light-absorbing pigments and proteins that capture and transfer energy in the thylakoid membrane

chloroplast

organelle composed of numerous membranes that are used to convert solar energy into chemical energy; contains chlorophyll

stroma

the fluid-filled space surrounding the thylakoids in chloroplasts where the light-independent reactions (Calvin Cycle) of photosynthesis occur

equation for photosynthesis

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂
