​Cellular Respiration

​

​Cellular respiration is a series of chemical reactions that change glucose in food in to a form of energy called ATP

​Al Bawadi School

​Cellular Respiration

​

​Step 1 of Cellular Respiration:

​- This step is called glycolysis

- Happens inside the cytoplasm​

- Cytoplasm is the liquid inside the cell

- ​Glucose is broken down into smaller molecules

​Cellular Respiration

​

​Step 2 of Cellular Respiration:

​- Happens inside mitochondria

- Mitochondria is an organelle inside the cell

- ​The smaller molecules and oxygen are converted into ATP, water and carbon dioxide.
