Introduction

• Both matter and energy are essential in sustaining life• While humans and other animals use cellular respiration to

breakdown molecules and use energy, plants use photosynthesis

• Photosynthesis uses light as its activation energy

Light as Activation Energy

• Light is not matter• Light is the vibration of

photons in the form of electromagnetic waves

• Travel in different magni- tudes that the human mind defines as colors

• Photosynthetic pigments within plants absorb photons of different magni- tudes

• Pigments are found on exterior of thylakoids

Thylakoids

Uses ATP and NADPH

Hosts first step of photosynthesis and the only light-dependent step

Use energy of photons to power electron transport chains

Found in groups called granum

Forms ATP when protons travel through synthase

Lumen

Calvin’s Cycle

• Where glucose is created, and NADPH and ATP are reduced• Light-independent • Reactants are CO2, H20, and activation energy from carriers• Located in the stroma of the chloroplast• Is very similar to Kreb’s Cycle of the mitochondria

Conclusion

• Glucose is essential for success of life on earth• Present in various forms and seen within different mechanical

operations found anywhere• Humans also require glucose because of what we consume• Photosynthesis is required to naturally form glucose
