Unit C: Photosynthesis and Cellular Respiration Flashcards
Photon
a packet of light
Chlorophyll
the light-absorbing green-coloured pigment that begins the process of photosynthesis
Chloroplast
a membrane-bound organelle in green plant and algal cells that carries out photosynthesis
Stroma
the protein-rich semiliquid material in the interior of a chloroplast
Thylakoid
a system of interconnected flattened membrane sacs forming a separate compartment within the stroma of a chloroplast
Grana
stacks of thylakoids
Lamellae
groups of unstacked thylakoids between grana
Thylakoid Membrane
the photosynthetic membrane within a chloroplast that contains light-gathering pigment molecules and electron transport chains
Thylakoid Lumen
the fluid-filled space inside a thylakoid
Carbon Fixation
the process of incorporating carbon dioxide into carbohydrate molecules
Photolysis
a chemical reaction in which a compound is broken down by light
Oxidation
a reaction in which an atom or molecule loses an electron
Reduction
a reaction in which an atom or molecule gains an electron
Chemiosmosis
a process for synthesizing ATP using the energy of an electrochemical gradient and the ATP synthase enzyme
Active Transport
the movement of substances through a membrane
