|---|---|
 cellular respiration | process that releases energy from food in the presence of oxygen |
| 6O2 + C6H12O6 - - - 6CO2 +6H2O + Energy | formula for cellular respiration - Oxygen + Glucose ---- Carbon dioxide + Water + Energy |
| calorie | amount of energy needed to raise the temperatur of 1 gram of water 1 degree (unit) |
| ATP | energy made by cells using respiration |
| aerobic | cellular respiration that requires oxygen |
| anaerobic | does not require oxygen for cellular respiration |
| glycolysis | anaerobic part of cellular respiration because its final products are key reactants for the aerobic stage (takes place in mitochondria) |
| fermentation | anaerobic pathway makes it possible for the cell to keep glycolysis running creating ATP |
| krebs cycle | aerobic process for cellular respiration |
| stages of cellular respiration | glycolysis - krebs cycle - electron transport chain |
| electron transport chain | final stage of cellular respiration uses oxygen |
| pyruvic acid | chemical bond of a molecule formed during glycolysis |
| photosynthesis | the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce carbohydrates and oxygen |
| compare photosynthesis and cellular respiration | photosynthesis removes carbon dioxide from the atmosphere and cellular respiration puts it back. photosynthesis releases oxygen into the atmosphere and cellular respiration uses that oxygen to release energy from food |
