Day 4 Flow of Matter and Energy
Where does energy come from?
Cellular Respiration: PS and CR cycle Flow of Matter and Energy Sun: Light Energy Photosynthesis: Light Dependent and Calvin Cycle In the Chloroplast Water and Carbon Dioxide Glucose (Sugar) and Oxygen Cellular Respiration: Krebs Cycle and Electron Transport Chain In the Mitochondria ATP: Chemical Energy 86 87
Flow of Matter and Energy Slide 1 of 3 Flow of Matter and Energy EQ: How does matter flow between abiotic and biotic factors? Decomposers (Bacteria) Consumers/ . Heterotrophs Producers/ Autotrophs Main Energy: Sunlight 10% moves to next level (Q1) (Q2) 10 calories Energy 100 calories 1,000 calories The energy from the Sunlight is absorbed by Autotrophs producing Glucose through Photosynthesis The energy from Glucose (Food) goes through Cellular Respiration or Fermentation to produce ATP.
Slide 2 of 3 Energy (Cont.) Adenosine Tri-Phosphate: the usable energy of cells. A P P P (Q3) Living things need energy to survive. Energy stored as ATP in cells. Energy is released by breaking the chemical bond between the 2nd and 3rd phosphates. Adenosine Di-Phosphate Adenosine Tri-Phosphate Energy Partially charged battery Fully charged battery
Flow of Matter and Energy Slide 3 of 3 Flow of Matter and Energy Photosynthesis and Cellular Respiration have three important elements: Carbon, Hydrogen, and Oxygen H2O Water (liquid) CO2 Carbon Dioxide O2 Oxygen (gas) C6H12O6 Sugar/Glucose There are more elements and molecules involved, but these are the main molecules you’ll need to learn.
