Respiration Respiration Respiration is the process by which
Respiration
Respiration • Respiration is the process by which cells obtain energy from glucose (sugar) • During respiration, cells break down simple food molecules and release the energy that they contain. • This type or respiration is referred to as cellular respiration (breaking down food) not to be confused with respiration (breathing – bring in oxygen)
The Two Stages of Respiration • Like photosynthesis, respiration is a two-stage process. • Respiration occurs in the mitochondria of the cell. • Respiration takes place in both plant and animal cells.
#1
Stage 1 • Takes place in the cytoplasm. • Glucose is broken down into smaller molecules. • Oxygen is not involved • A small amount of energy is released.
Takes place in the cytoplasm. Glucose is broken down into smaller molecules. Oxygen is not involved A small amount of energy is released. #2
Stage 2 • Takes place in the Mitochondria. • The small molecules are broken down into even smaller molecules. • These chemical reactions require oxygen and release a great deal of energy. • Mitochondria = powerhouses of cell.
Takes place in the cytoplasm. Glucose is broken down into smaller molecules. Oxygen is not involved A small amount of energy is released. Takes place in the Mitochondria. The small molecules are broken down into even smaller molecules. These chemical reactions require oxygen and release a great deal of energy. Mitochondria = powerhouses of cell. #3
