What
What is the process of breaking down glucose in the presence of oxygen?
Aerobic respiration
How is energy released in aerobic respiration?
Through the breakdown of glucose.
Why does aerobic respiration produce more ATP than anaerobic?
Because glucose is fully oxidized (fully broken down) using oxygen.
Where does anaerobic respiration take place?
Cytoplasm
What gas is released during aerobic respiration?
Carbon dioxide
How do aerobic and anaerobic respiration both begin?
Both begin with glycolysis in the cytoplasm.
Why is aerobic respiration more efficient than anaerobic?
It yields much more ATP per glucose molecule.
Where in the body can anaerobic respiration happen often?
In the muscles.
What is the common first step in both aerobic and anaerobic respiration?
glycolysis
How do muscles switch from aerobic to anaerobic respiration during exercise?
When oxygen runs low, muscles stop aerobic respiration and start anaerobic respiration to keep releasing energy.
Why do organisms need respiration?
To get energy from glucose.
Where does aerobic respiration happen?
In the mitochondria.
What is the process of breaking down glucose without oxygen?
Anaerobic respiration
How do aerobic and anaerobic respiration differ?
One uses oxygen, the other doesn’t
Why does anaerobic respiration happen?
Because there isn't enough oxygen.
Where does carbon dioxide get released from during respiration?
Cells
