Cellular Respiration and Photosynthesis

Cellular Respiration

Organisms have the ability to transform energy from one form to another with sunlight

What chemical energy is converted from sunlight?

Glucose

Cellular respiration turns the glucose into

adenosine triphosphate (ATP)

Anaerobic

in the absense of oxygen

Aerobic

in the presence of oxygen

Glycolysis

Breaking down of glucose to release the potential energy

Major end net products of glycolysis

Two molecules of ATP

Two moleules of NADH (co-enzyme)

Two molecules of pyruvate

Visible spectrum

light visible to the naked eye

White light

Variety of colors ranging from red to violet

Electromagnetic spectrum

Radio waves, visible light, x rays, and cosmic rays

Pigments

absorb light energy and to use energy

Chlorophyll

most important pigment in photosynthesis

Chlorophyll a

Main photosynthetic pigment in cyanobacteria and plants

Thylakioid

initiates photosynthesis

Stroma

semifluid matrix inside the chloroplast

Photosynthesis chemical equation

6CO₂ + 6H₂O + light energy = C₆H₁₂O₆+6O₂

Cellular Respiration

C₆H₁₂O₆ + 6O₂ = 6CO₂ + 6H₂O + ATP

Light-dependent reactions

Chlorophyll a

Light-independent reactions

Calvin cycle

Calvin cycle

CO₂ is fixed to form sugars and O₂ released. (located in stroma)
