PHOTOSYNTHESIS

CAPTURING THE ENERGY IN LIGHT All organisms use energy to carry out the functions of life.  Some organisms obtain this energy directly from sunlight.  They capture part of the energy in light and store it within organic compounds.  The process by which this energy transfer takes place is called PHOTOSYNTHESIS.

Photosynthesis is the process that provides energy for almost all Life

OBJECTIVES   Explain how the structure of the chloroplast relates to its function Explain how ATP is synthesized during the light reactions

They begin with the ABSORPTION of Light in the organelle found in Plant Cells and algae called CHLOROPLASTS

During Photosynthesis, Autotrophs use the Sun's Energy to make Carbohydrate Molecules from Water and Carbon Dioxide, Releasing Oxygen as a Byproduct

The Process of PHOTOSYNTHESIS CAN BE SUMMARIZED BY THE FOLLOWING EQUATION               6CO2       +       6H2O    +      LIGHT               C6H12O6          +              6O2            CARBON       WATER     ENERGY                 6-CARBON                 OXYGEN            DIOXIDE                                                                 SUGAR                         GAS   In this equation the Six-Carbon Sugar GLUCOSE and Oxygen are the Products. The Energy Stored in Glucose and other Carbohydrates can be used later to produce ATP during Cellular Respiration

Draw the following chart:

Most AUTOTROPHS or PRODUCERS use PHOTOSYNTHESIS, to Convert the Energy in SUNLIGHT, CARBON DIOXIDE, AND WATER  into Chemical Energy OR FOOD.  (GLUCOSE) THE FOODS MADE BY AUTOTROPHS ARE stored in various Organic Compounds, primarily CARBOHYDRATES, including a SIX-CARBON SUGAR called GLUCOSE.

Cellular Respiration

Autotrophs, such as plants, use photosynthesis to convert light energy from the Sun into Chemical energy, which is stored in Carbohydrates and other Organic Compounds. Both Autotrophs and Heterotrophs depend on these Organic Compounds for the energy to Power Cellular Activities. By Breaking Down Organic Molecules into simpler molecules, CELLS RELEASE ENERGY. Some of the energy is used to make ATP from ADP and Phosphate.  ATP is the Main Energy Currency of Cells.

Cellular Respiration The Complex Process in which Cells Make ATP by Breaking Down Organic Molecules is known as CELLULAR RESPIRATION. OR THE PROCESS BY WHICH FOOD MOLECULES ARE BROKEN DOWN TO RELEASE ENERGY FOR WORK IS CALLED CELLULAR RESPIRATION

PHOTOSYNTHESIS EQUATION: 6CO2 +  6H2O + LIGHT ENERGY    C6H12O6  + 6O2 Sugar oxygen

CELLULAR RESPIRATION EQUATION  C6H12O6 + 6O2    6CO2   +   6H2O +   ENERGY RELEASED (ATP) the metabolic processes whereby certain organisms obtain energy from organic molecules, processes that take place in the cells and tissues during which energy is released and carbon dioxide is produced and absorbed.
