  • Go Green to Grow Green-Photosynthesis

    The Carbon Cycle

  • Photosynthesis and Respiration in Plants

    Photosynthesis: The process in which plants use CO2, sunlight, and H2O to produce sugars and Oxygen.

    2011 Science Education Resource Center, San Jose State University

  • Photosynthesis and Respiration in Plants

    Respiration: The process in which plants use the sugars produced by photosynthesis to create ATP.

    2011 Science Education Resource Center, San Jose State University

  • Photosynthesis and Respiration in Plants

    ATP: The universal energy source, which all living things use to do work.

    2011 Science Education Resource Center, San Jose State University

  • Photosynthesis 6CO2 + 12H2O + Light = C6H12O2 + 6O2 + 6H2O

    Input:

    Sunlight

    CO2 (Carbon Dioxide)

    H2O (Water)

    Output:

    C6H12O2 (Glucose)

    O2 (Oxygen)

    H2O (Water)

  • Light-dependent Reaction

    2011 Science Education Resource Center, San Jose State University

    PresenterPresentation Notes-Capture of light energy with light absorbing pigments, i.e. chlorophyll. -Produces oxygen by the photolysis of water. -Electron transport chain Produces NADPH directly Produces ATP indirectly through a proton gradient

  • 2 Stages of Photosynthesis

    1. Light-dependent Reaction

    2. Light-independent Reaction

    (Calvin Cycle)

  • “Dark” Cycle

    It requires ATP, NADPH and CO2 to synthesize glucose (sugar) or other carbohydrates.

    Energy generated to “fix” carbon comes from these molecules generated from light reaction.

    It does NOT happen at night! It is light-independent (does not require photons).

  • Light Independent Reaction Calvin Cycle

    Carbon “fixed” by using RuBP (Ribulose bisphosphate) and RuBisCO

    Fixed: Convert C in the gaseous form (CO2) into a solid structure using the energy created by ATP and NADPH

  • RuBisCO Crucial for carbon fixation

    Create organic carbon from inorganic carbon in the atmosphere

    Most abundant protein on earth because it is slow

    fixes three CO2 molecules per second instead of 1,000

  • Temperature Affects RuBisCO

    PROBLEM: Rubisco binds with oxygen attaches oxygen to the sugar chain, forming a faulty oxygenated product. The plant cell must then perform a costly series of salvage reactions to correct the mistake.

    At HIGH temperatures: the oxygenating reaction of RuBisCO increases more than the carboxylating one.

    At LOW temperatures: slows molecular motion, i.e. molecular collisions, which decrease enzyme activity.

  • 3 Stages:

    For every 6 molecules of CO2 entering the cycle, 12 molecules of G3P and 1 molecule of Glucose are produced.

    http://www.uic.edu/classes/bios/bios100/f06pmlect08.htm

  • (1) Carbon Dioxide Fixation:

    1. Carbon dioxide reacts with ribulose bisphosphate (RuBP), P-C-C-C-C-C-P

    2. This occurs under the influence of the enzyme ribulose bisphosphate carboxylase (RuBisCO) • RuBisCO: the most abundant protein on the planet.

    3. RuBP has 5 C atoms and 2 phosphate groups, and by accepting one more carbon atom from CO2 it should be converted into a 6 carbon, 2 phosphate compound. However ...

    2011 Science Education Resource Center, San Jose State University

  • (2) Carbon Dioxide Reduction

    This compound is immediately converted into 2 molecules of glycerate 3-phosphate (GP, G3P, or PGAL), C-C-C-P

    Since PGAL is at a HIGHER energy state than RuBP, the reduced NADP and ATP provide the reducing power (H and Pi) for energy.

    Two out of the twelve PGAL molecules are removed from the cycle, to be converted into glucose, or other molecules such as starch, lipid or protein.

    2011 Science Education Resource Center, San Jose State University

  • (3) RuBP Regeneration 1. In a complex series of reactions, the remaining ten

    molecules of G3P are converted into 6 molecules of the 5-carbon compound ribulose monophosphate, C-C-C-C-C-P

    2. Ribulose monophosphate is converted into RuBP, using a phosphate group from ATP.

    3. RuBP reacts with carbon dioxide (becomes carboxylated), to keep the cycle operating again.

  • Climate Change o Driven by an increase in greenhouse gases

    o Primary greenhouse gases include: water vapor, carbon dioxide, methane, and nitrous oxide

    o Carbon Dioxide is one of the key greenhouse gasses affecting plant growth

  • Effects of Increased CO2 Levels

    Plants can only absorb and process a limited amount of carbon dioxide because it is part of a system

    Limited by: Rubisco availability RuBP regeneration Sugar build up within Calvin cycle

  • A-Ci Curve Plants’ Photosynthetic Capacity

  • How does climate change affect photosynthesis???

    1. Change in temperature

    Affects the rate of enzyme reactions Rubisco

    Affects water access

    Drought Freezing

    2. Change in rain fall Reduction in H2O availability

    3. Seasonal plants Adapted to specific climate cycles
