|---|---|---|---|---|---|
| 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
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
