Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2014, CO2 accounted for about 80.9 of all U.S. greenhouse gas emissions from human activities.

Products of Photosynthesis = Reactants of Cellular Respiration 

# data[].attributes.body
Most of the steps of cellular respiration take place in the mitochondria. Oxygen and glucose are both reactants in the process of cellular respiration. The main productof cellular respiration is ATP; waste products include carbon dioxide and water.

is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.

energy is equal to mass multiplied by the square of the speed of light. Because the speed of light is a very large number in everyday units, the formula implies that any small amount of matter contains a very large amount of energy

can neither be created nor destroyed, but can be change from one form to another. The law of conservation of mass states that the total amount of mass remains constant in an isolated system in spite of any physical or chemical changes that may take place.

states that the total energy of an isolated system remains constant—it is said to be conserved over time. energy can neither be created nor destroyed; rather, it transforms from one form to another.

# data[].attributes.body
states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system mass cannot change quantity if it is not added or removed. Hence, the quantity of mass is "conserved" over time.

Conversion of light energy to chemical energy

# data[].attributes.body
Light energy is converted to chemical energy when a photo chemically excited special chlorophyll molecule of the photosynthetic reaction center loses an electron, undergoing an oxidation reaction.

the first stage of the Calvin cycle, light-independent reactions are initiated; CO2 is fixed from an inorganic to an organic molecule
In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADP+, respectively.
in the last stage of the Calvin Cycle, RuBP is regenerated, which enables the system to prepare for more CO2 to be fixed

the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH.

convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast. Plants are the basis of all life on Earth. They are classified as the producers of the world.
