Aerobic and anaerobic respiration Flashcards
Chemical reactions in cells are controlled by…
…enzymes.
An aerobic respiration is respiration with what?
With oxygen.
Aerobic respiration uses what?
Glucose and oxygen.
Respiration occurs in order to release what?
Release energy.
True or false, aerobic respiration takes place continually in plants and animals.
True.
Most reactions in aerobic respiration take place where in the cell?
In the mitochondria.
Equation for aerobic respiration:
Glucose + oxygen
->
Carbon dioxide + water (+energy)
Energy released in respiration can be used in the organism to:
Build larger molecules from smaller ones.
Enable muscles to contract in animals.
Maintain a steady body temperature in colder surroundings (mammals and birds).
Build up sugars, nitrates and other nutrients into amino acids which are then built up into proteins, in plants.
What changes to the body take place during exercise?
Heart rate increases.
Rate and depth of breathing increases.
Changes in heart rate, breathing rate and breathing depth mean what for respiration?
Increased blood flow to the muscles, so increased supply of sugar and oxygen and increased rate of removal of carbon dioxide.
Muscles store what that can be converted to glucose during exercise?
Glycogen.
During exercise, when there is insufficient oxygen supply, what can take place so that energy is released?
Anaerobic respiration.
Anaerobic respiration is what?
The incomplete breakdown of glucose into lactic acid.
Anaerobic respiration is incomplete decomposition of glucose, what effect does this have on amount of energy produced?
Less energy is produced than aerobic respiration.
Anaerobic respiration results in what kind of debt?
Oxygen debt.
