Producers (Autotrophs or photosynthetic organisms)
living things that make their food from CO₂ and H₂0 (ex plants, algae)
living things that get energy by eating
types of consumers are herbivores, carnivores, omnivores, decomposers
aerobic harvesting of chemical energy from organic fuel molecules (a living version of internal combustion)
-the main way that chemical energy is harvested from food and converted to ATP
-It is AEROBIC process because it REQUIRES OXYGEN
Reasons for the need of energy
-keep the heart pumping blood
-Maintain consistent body temperature
Acceptance of electrons
-Oxygen is reduced during cellular respiration accepting electrons (and H) lost from glucose
Oxidation-Reduction Reactions (redox reactions)
chemical reactions that transfer electrons from one substance to another
Steps of Cellular Respiration
1. Glycolysis -Anaerobic
2. Citric Acid (Kreb's Cycle) -Aerobic
3. Oxidative Phosphorylation -Aerobic
