Photosynthesis

1. Photosynthesis Incorporation of light energy, and explanation of the chemical processes of By: Nick James Elli Nassivera Ryan Liss and kevin

2. 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

3. 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

4. Thylakoids Hosts first step of photosynthesis and the only light-dependent step Found in groups called granum Use energy of photons to power electron transport chains Forms ATP when protons travel through synthase Uses ATP and NADPH Lumen

5. 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 Video: http://www.youtube.com/watch?v=E_XQR800AgM

6. 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
