What is the process of breaking down glucose in the presence of oxygen?

Aerobic respiration

100

How is energy mainly released in aerobic respiration?

Through the breakdown of glucose.

100

Why does aerobic respiration produce more ATP than anaerobic?

Because glucose is fully oxidized using oxygen.

100

Where does anaerobic respiration mainly take place?

Cytoplasm

200

What gas is released during aerobic respiration?

Carbon dioxide

200

How do aerobic and anaerobic respiration both begin?

Both begin with glycolysis in the cytoplasm.

200

Why is aerobic respiration more efficient than anaerobic?

It yields much more ATP per glucose molecule.

200

Where in the body can anaerobic respiration happen often?

In the muscles.

300

What is the common first step in both aerobic and anaerobic respiration?

glycolysis

300

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.

300

Why do organisms need respiration?

To get energy.

300

Where does aerobic respiration mostly happen?

In the mitochondria.

400

What is the process of breaking down glucose without oxygen?

Anaerobic respiration

400

How do aerobic and anaerobic respiration differ?

One uses oxygen, the other doesn’t

400

Why does anaerobic respiration happen?

Because there isn't enough oxygen.

400

Where is carbon dioxide released during respiration?
