What is the balanced equation for aerobic respiration?
$C_6H_{12}O_6 +$ $6O_2 \rightarrow 6CO_2 +$ $6H_2O +$ $\text{energy}$
What happens to breathing and heart rate during exercise?
They increase to deliver more oxygen to cells
What is anaerobic respiration?
Respiration that occurs without oxygen
What is produced during anaerobic respiration in muscles?
Lactic acid
What is oxygen debt?
The amount of oxygen needed to break down lactic acid
What do plant and yeast cells produce during anaerobic respiration?
Ethanol and carbon dioxide
What is fermentation?
The process of anaerobic respiration in yeast
What is the role of mitochondria in cells?
Site of aerobic respiration
Provides energy for cellular processes
What are the differences between aerobic and anaerobic respiration?
Aerobic: occurs with oxygen, produces more energy
Anaerobic: occurs without oxygen, produces less energy and lactic acid (in muscles)
