2.6 Aerobic And Anaerobic Respiration Flashcards
What are chemical reactions in cells controlled by continuously?
Enzymes
What is the word equation for aerobic respiration?
Glucose + Oxygen -> Carbon dioxide + Water
What is the balanced symbol equation for aerobic respiration?
C6H12O6 + 6O2 -> 6CO2 + 6H2O
What is the purpose of taking in glucose and oxygen in aerobic respiration?
To produce energy
What are carbon dioxide and water in aerobic respiration?
Waste products
Where does most of the chemical reactions of aerobic respiration take place?
In the mitochondria
What can the energy released be used for from aerobic respiration in mammals and other animals?
Building larger molecules from smaller ones
Enable muscle contraction
Maintain a steady body temperature
What can energy released in aerobic respiration be used for in plants?
Build sugars, nitrates and other nutrients
Into amino acids which are built into proteins
What test could you do to see if something is respiring aerobically?
Use limewater and if it goes cloudy CO2 is present
This is a bi-product of aerobic respiration
What is the effect of exercise on your body?
Your muscles need more energy when you exercise
So your heart rate increases and your rate and depth of breathing rate also
This increases blood flow to the muscles allowing more glucose and oxygen to reach the muscles
This will also increase that rate of CO2 removal
What do muscles store glucose as?
Glycogen
What can muscles do with Glycogen in exercise?
Turn it back into glucose
When does anaerobic respiration take place?
If insufficient oxygen is reaching the muscles
What is the word equation for anaerobic respiration?
Glucose -> Lactic acid (+energy)
Is more or less energy released in anaerobic respiration? Why?
Less
Because the respiration is incomplete
