Cell Respiration

Topic 2.8

Essential idea: Cell respiration supplies energy for the function of life.

Understandings

2.8.U1 Cell respiration is the controlled release of energy from organic compounds to produce ATP

Cell respiration is the controlled release of energy from organic compounds in cells to form ATP. The equation for aerobic cellular respiration is shown below.

Equation Respiration

2.8.U2 ATP from cell respiration is immediately available as a source of energy in the cell

ATP used immediately

2.8.U3 Anaerobic respiration gives a small yield of ATP from glucose

Use the figure below to explain glycolysis and anerobic respiration

Place mouse pointer on the figure to show the explanation of glycolysis and anaerobic respiration.
