Aerobic And Anaerobic Respiration Flashcards
What is aerobic respiration?
Respiration that use so oxygen
During aerobic respiration what chemical reaction occurs?
Ones which uses glucose (a sugar) and oxygen
Releases energy
Aerobic respiration takes place….
Continuously in both animals and plants
Where do most reactions in aerobic respiration take place?
Inside mitichondria
What is the equation for aerobic respiration?
Glucose + oxygen ——> carbon dioxide + water (+energy)
What is the energy that is released during respiration used by and for?
By the organism
For:
To build larger molecules from smaller ones
In animals, to enable muscles to contrac
In mammies and birds, to maintains a steady body temperature in colder surroundings
In plants, to build up sugars, nitrates and other nutrients into amino acids which are then built up into proteins
What are the changes which take place when you do exercise?
The heart rate increases
The rate and depth of breathing increases
What do muscles store?
Glycogen (a chemical), which can then be converted back to glucose when your blood sugar is low or during exercise. It can then be converted back into glycogen
When does anaerobic respiration take place?
During exercise, if insufficient oxygen is reaching the muscles they use anaerobic respiration to obtain energy
What is anaerobic respiration?
It is the incomplete breakdown of glucose and produces lactic acid.
As the breakdown of glucose is incomplete, much less energy is released than during arp erotic respiration. Anaerobic respiration results in an oxygen dept that has to be repaid in order to oxidise lactic acid to carbon dioxide and water
When do muscles become fatigued?
If muscles are subjected to long periodsd of vigorous activity
i.e. they stop contracting efficiently
Once cause of muscle fTigue is the build up of lactic acids in the muscle. Blood flowing through the muscle removes the lactic acid
What are chemical reactions inside the body controlled by?
Enzymes
