Question | Answer |
Where does cellular respiration occur? | In both plants and animals |
What happens in cellular respiration? | Cells break down glucose and turn it into energy. |
What form is the energy in? | The form of ATP |
How many reactions does Aerobic reactions involve? | approx 20 |
What are the reaction between? | Glucose and Oxygen |
What happens to the Glucose and Oxygen? | They are broken down to form Carbon Dioxide, Energy and Water |
Aerobic Reactions involve a series of reaction and have how many stages? | 3 stages |
What is the first stage called? | Glycolysis |
What is Glycolysis? | it is the first stage of the breakdown of glucose |
Where does it occur? | In the cytosol |
During this stage, each of the ..... Carbon ........... molecules are broken down into ... Carbon ........... molecules? | each of the 6 carbon glucose molecules are broken down into 3 carbon pyruvate molecules. |
How many ATP are released? | 2 |
What is the 2nd stage called? | Krebs cycle |
What happens the pyruvate molecules? | They go through the Krebs cycle |
Where is the Krebs cycle located? | In the matrix |
For each pyruvate molecules, what and how many are formed? | 5 'loaded' acceptor molecules are formed |
What is released? | Carbon Dioxide and 2 ATP. |
What is the 3rd stage called? | Electron Transport Chain |
Where does it take place? | In the inner membranes of the mitochondria. |
What happens to the electrons from the 'loaded' acceptor molecules? | Combine with Oxygen which reacts with hydrogen ions to form water. |
What does this electron transport do? | It releases energy |
What is released? | water and 32-34ATP |
When do Anaerobic reactions occur? | After glycolysis if oxygen is lacking. |
What are the inputs of Anaerobic reaction (humans)? | Glucose |
Outputs | Lactic Acid and 2ATP |
What are the inputs of Anaerobic reactions (plants)? | Glucose |
Outputs? | Ethanol, Carbon Dioxide and 2ATP |
