Energy From Respiration Flashcards
Which sugar is needed by the muscles for aerobic respiration
Glucose
What is aerobic respiration
The release of energy from food when oxygen is available
Where does aerobic respiration take place
Continually in plants and animals
What is the equation for aerobic respiration
Glucose + oxygen—> carbon dioxide+water [+energy]
The energy released may be used by the organism to
Enable muscle contraction
Maintain a constant body temperature in colder surroundings
Build sugars nitrates and other nutrients into amino acid’s and then proteins in plants
What needs to happen during exercise
The muscles need more energy so more glucose and oxygen needs to be transported to the muscles
Which substance is stored in the muscles and can be converted into glucose
Glycogen
What are the two waste products of aerobic respiration
Carbon dioxide and water
Explain what is meant by an oxygen debt
The amount of oxygen needed to break down the lactic acid produced in anaerobic respiration
Where does aerobic respiration take place
In the mitochondria
What is anaerobic respiration
Respiration without oxygen
Why do muscles become fatigued during vigourous exercise
Lactic acid buildup in the muscles
What’s remove lactic acid from muscles
When blood flows through the muscles lactic acid is removed
What happens when your muscles can’t get enough oxygen for aerobic respiration
They start to respire anaerobically
What is produced during anaerobic respiration
Lactic acid is produced as a waste product
