Can respiration take place with and without oxygen?
Yes it can
What do organisms use respiration for?
Release energy from food
What are the two types of respiration?
Aerobic and anaerobic
What is aerobic respiration?
Respiration in the the presence of oxygen, glucose fully broken down, lots of energy released
What is anaerobic respiration?
Respiration without oxygen, glucose not fully broken down into water and oxygen, less energy released
What is the word equation for aerobic respiration?
Glucose+oxygen—> CO2+water+energy
How can you detect CO2 given off in respiration?
Using lime water, turns cloudy if CO2 present
How can you detect heat given off during respiration?
Using a thermometer
When do humans respire without oxygen?
During vigorous exercise
What can both do anaerobic respiration?
Animals and yeast but each produce different products
Why do muscles ache during vigorous exercise?
Muscles start to respire without oxygen In this process lactic acid is produced Happens when glucose is broken down in the absence of oxygen Lactic acid= waste products
How much energy does anaerobic respiration release?
Little energy from food by partly breaking glucose without oxygen
Write an equation for anaerobic respiration
Glucose —> lactic acid+some energy
