Cellular Respiration Cellular respiration is the process that releases ___________ by breaking down glucose and other food molecules in the presence of oxygen. Both ___________ and ____________ cells use cellular respiration to release energy.
Cellular Respiration Equation The equation for cellular respiration is: _____+ _____ → _____ + _____ + _____ oxygen + glucose → carbon dioxide + water + Energy
2 Stages of Cellular Respiration Stage I: __________ –Takes place in the cytoplasm –Breaks down glucose into pyruvic acid (+2 ATP)
Stage 2: __________ (With Oxygen) –Aerobic –In Mitochondria –Goes through the Kreb’s Cycle (+2 ATP) –Goes through Electron Transport Chain (up to +34 ATP) OR Stage 2: _____________ (Without Oxygen) –Anaerobic –In Cytoplasm –Two Types: Lactic Acid or Alcohol 2 Stages of Cellular Respiration
