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