Photosynthesis
Light Dependent Reactionvs.
Light Independent Reaction
Light Dependent Reaction• Light, water, NADP+, and ADP enter the thylakoid.• Oxygen, ATP, NADPH leave• Requires light to occur• Stores energy temporarily
Light Independent Reaction
• Also known as Calvin cycle• ATP, NADPH, and CO2 enter• ADP,NADP+, and sugar exit• Stores energy for long period of time. • Does not need light to occur
• Which reaction stores energy temporarily?¿Qué reacción almacena energía
temporalmente?
• Which stores energy for long periods of time?¿Cuál almacena la energía por períodos del
tiempo largos?
Gas Exchange
• Stomata-– Openings in the leafs where gases can enter and
leave
• Which gas enters through the stomata?¿Qué gas entra a través de los estomas?
• Which gas leaves through the stomata?¿Qué gas se va a través de los estomas?
Photosynthesis is affected by…
• Sunlight• Water availability• CO2• Temperature
• How could you test whether light intensity effects photosynthesis?
¿Cómo podría usted probar si la intensidad de luz efectúa fotosíntesis?
ATP vs. ADP
• Energy carrier
• Adenosine Triphosphate
vs. Adenosine Diphosphate
NADPH vs. NADP
• Electron carrier• Accepts H+ from Water
• What is the electron carrier for the chloroplast?
¿Cuál es el portador del electrón para el cloroplasto?
• What is the energy carrier for the reaction?¿Cuál es el portador de energía para la reacción?
Parts of the Chloroplast
• The light independent reaction takes place in the ___________.
La reacción independiente ligera ocurre en el ___________.
• The light dependent reaction takes place in the ___________.
La reacción dependiente ligera ocurre en el ___________.
• What is a stack of thylakoids called?¿Qué un apilado de thylakoids se llama?
• Where does photosynthesis take place?¿Dónde la fotosíntesis ocurre?
Chlorophyll
• Pigment that traps sunlight• Absorbs all colors but green• The chloroplast is green because green is reflected
