Cellular Respiration ABBY WADSWORTH



  • gylcolysis is the first step in both cellular respiration and fermentation
  • takes place in the cytoplasm
  • occurs in all living organisms
  • occurs with both aerobic and anaerobic pathways
  • inputs: glucose, 2 ATP, 2 NAD+, 4 ADP + P
  • outputs: 2 pyruvates, 4 ATP (2 net), 2 NADH + H, 2H2O


  • 2nd step in cellular respiration
  • takes place in the matrix of the mitochondria
  • pyruvic acid is broken down into CO2
  • more NADH are made
  • releases 2 more ATP
  • inputs: CoA, NAD+, acetyl acid, 2 NAD+, ADP+P, FAD, NAD+
  • outputs: CO2, NADH, CoA, 2 NADH, ATP, FADH, NADH, 4 c-molecules


  • occurs in the mitochondria
  • 34 ATP made
  • water is made
  • converts stored energy to potential energy
  • it is a series of proteins
  • occurs in the inner membrane so there is more surface area for ATP production

Importance of Cellular Respiration

Cellular respiration is important because it provides energy that living organisms need in order to preform functions and maintain life.
