Photosynthesis and Respiration
Photosynthesis CO 2 + H 20 C 6 H 12 O 6 + O 2
Energy…. • Purpose = make energy • Sunlight energy chemical energy
Plant Color • Plants absorb & use blue, indigo, violet, and red light. • Green light is reflected
Bonds & Energy • Energy stored in bonds of sugars (like glucose) and starches • Breaking bonds releases energy C X– C = Energy
Photosynthesis requires pigments… • Chlorophyll- pigment (green) • Chlorophyll in chloroplasts • Pigments can also be * yellow * orange (fall leaves) * red (tomatoes)
In summary…. . • We eat plants to get energy (or we eat animals that ate plants to get energy) • Our energy comes from plants • The ultimate energy source is the SUN
Cellular Respiration Equation C 6 H 12 O 6 + 6 O 2 6 CO 2 + 6 H 2 O + ATP Purpose: Use Energy
• • Respiration = cellular respiration Glucose ATP = Usable Energy Both plants and animals use cellular respiration • Breathing cells get oxygen • Eating cells get glucose
• Respiration can be: O 2 anaerobic = O 2 – aerobic = – Ø • BOTH produce
Glycolysis • Glucose breaking • NO oxygen- Anaerobic • Makes a little ATP Glucose
Glycolysis is Just the Beginning… Glucose will be broken down more to release more
Aerobic Pathway • Krebs Cycle & Electron Transport Chain (ETC) • Requires O 2 • If oxygen is not available, then it will NOT occur • Produces buckets of ATP! • It is the pathway of choice b/c it produces so much energy
Anaerobic Pathway (Fermentation) • • Requires NO oxygen Produces a little ATP Used only when necessary Alternative to the aerobic pathway
Lactic Acid Fermentation • Makes lactic acid • Lactic acid buildup burning in muscles during a strenuous workout • Large muscles run out of oxygen • Fermentation starts to try and get the ATP muscles need
• • • Alcoholic Fermention Occurs in yeast cells Produces alcohol Important to bakers & brewers CO 2 is released by yeast CO 2 causes bubbles of sparkling wine & beer
Respiration Overview
Obtaining energy from foods. . • More than glucose is needed diet • Complex carbohydrates must be broken down into simple sugars • Remember all carbohydrates are chains of simple sugars • The cell can burn multiple energy sources like a furnace burns different fuels
Autotrophs vs. Heterotrophs • Autotrophs make their own food • Heterotrophs must obtain their energy from other organisms • Plants are autotrophs • People and animals are heterotrophs Autotroph Heterotroph
Photosynthesis & Respiration • Two sides of the same coin • Photosynthesis makes deposits in the “energy bank” • Respiration makes withdrawals • The equations are opposites of one another
