What is aerobic respiration?
How energy is released from glucose with oxygen
What is anaerobic respiration?
How energy is released from glucose without oxygen
Where does aerobic respiration happen in a eukaryotic cell?
In the mitochondria
In what cell does anaerobic respiration happen?
In the cytoplasm
What is the balanced chemical equation for aerobic respiration?
C6H12O6+ 6O2→ 6CO2 + 6H2O
What is the word equation for anaerobic respiration in animal cells?
Glucose →lactic acid
What is the word equation for anaerobic respiration in plant and yeast cells?
Glucose→ ethanol+ carbon dioxide
Is more or less energy transferred in anaerobic repsiration compared to aerobic respiration?
Less due to incomplete breakdown of glucose
How have humans used anaerobic respiration in plant and yeast cells to make food and drink?
production of bread and alcoholic drinks
Why does the heart rate increase during excercise?
To supply more blood to muscle cells
Which reactants for aerobic respiration does the blood contain?
Glucose(in plasma) and oxygen (in red blood cells)
Name 3 physical ways in which the human body reacts to an increased demand for energy
heart rate, breathing rate and breath volume all increase
Which chemical is produced in respiring muscle cells if there is not enough oxygen?
Lactic acid
Which complex carbohydrate is stored in the muscle cells to provide chemical energy
Glycogen
What is an oxygen debt?
The amount of extra oxygen the body needs after exercise to react with the accumlated lactic acid and remove it from the cells
