PHOTOSYNTHESIS & CELLULAR RESPIRATION How energy is made within…. .
Photo = light Synthesis = to make Autotrophs convert light energy into glucose (sugar)
PHOTOSYNTHESIS EQUATION + ₂ O C 6 + O ₂ 6 H y g r e n E t h Lig ₂ O 6 + ₆ O ₂ ₁ H ₆ C
I. Light Absorption A. Photosynthesis (light reactions) occur in chloroplast B. Light travels as waves 1. Objects absorb different wavelengths of color 2. The color you see is the color that is being reflected back at you. 3. ROYGBIV * (Red, Orange, Yellow, Green, Blue, Indigo, Violet)
Pigments absorb light Photosynthesis requires light and chlorophyll (green pigment)
III. Photosynthesis Reactions A. Light Dependent Reaction Needs Sun B. Calvin Cycle (light independent Reaction) Does Not Need Sun Carbon Fixation occurs (putting carbon into molecules)
V. Rate of Photosynthesis Rate is affected by: 1. Sunlight 2. Temp 3. Carbon Dioxide
Cellular Respiration How animals make energy or ATP…. .
Cellular Respiration and Photosynthesis Relationship They are opposites in the energy world and in equations Cellular Respiration occurs in organisms in the mitochondria Photosynthesis occurs in plants in the chloroplast
CELLULAR RESPIRATION EQUATION C₆ H₁ ₂O ₆ +6 O₂ 6 CO ₂+ 6 H ₂O + AT P
Cellular Respiration There are 3 main cycles where ATP is produced: Kreb’s Cycle Electron Transport Chain
Anaerobic vs. Aerobic Some cycles require oxygen some do not Anaerobic – do not require Oxygen ◦ Glycolysis ◦ Fermentation (ATP not made) Aerobic – requires Oxygen to make ATP ◦ Kreb’s Cycle ◦ ETC (Electron Transport Chain)
2 types Fermentation Alcoholic Used for: ◦ Yeast in bread ◦ Wine ◦ Sauerkraut Products: ◦ CO₂ ◦ NAD ◦ Alcohol Lactic Acid Used by: ◦ Muscles when over exercised Products ◦ NAD ◦ Lactic Acid NAD=Nicotinamide Adenine Dinucleotide. It is an activated form of B vitamin niacin used as a dietary supplement
