Cellular Respiration Ingredients Products

Ingredients: • 1. Oxygen (O 2) • 2. Glucose (C 6 H 12 O 6)

Oxygen enters through the process of… • Oxygen enters the cell through the process of diffusion, which is the movement of molecules from high to low concentration. • When you breathe in, there is a higher concentration of oxygen located outside your cells than inside. • Therefore, the oxygen diffuses into the cell.

Glucose enters a cell through the process of… • Glucose enters a cell through the process of active transport, which is the movement of molecules from low to high concentration. • Your cells never want glucose to leave a cell. • The extra glucose inside the cell will be stored for later use.

Cellular Respiration Ingredients Products

Product: • 1. Carbon Dioxide (CO 2)

C 02 exits a cell through the process of… • CO 2 is transported out of a cell by the process of diffusion. • After cellular respiration, there is a higher concentration of C 02 on the inside than outside of the cell • Therefore, the extra C 02 diffuses out of the cell

Making Connections • Directions: Using information in this Power. Point, write the following: • 1. A description of cellular respiration • 2. Explain how diffusion, active transport and cellular respiration are connected
