Respiration Flashcards
What is respiration?
The process of releasing energy from glucose
In what cells does respiration occur?
All of them
What type of organisms respire?
All of them
What is the difference between aerobic and anaerobic respiration?
Aerobic uses oxygen
Which is the most efficient way to release energy from glucose?
Aerobic respiration
When does aerobic respiration happen?
All of the time
Where does most of the reactions in aerobic respiration occur?
Mitochondria
What is the word equation for aerobic respiration?
Glucose+Oxygen—->Carbon Dioxide+Water+Energy
What are the 4 ways organisms use energy?
Build large molecules from smaller one
Allow muscles to contract for movement (animals)
Maintain Body Temp (mammals and birds)
Build sugars, nitrates and other nutrients into amino acids and then proteins (plants)
What happens during physical activity?
Increase speed at which heart pumps
Increase breathing rate and breath deeper
Why does blood flow at a faster rate during Excercise?
Glucose and oxygen need to be supplied to muscle cells
Carbon dioxide needs to be removed
Why does blood flow at a faster rate during Excercise?
Glucose and oxygen need to be supplied to muscle cells
Carbon dioxide needs to be removed
Why does breathing rate increase during exercise?
Higher demand for oxygen
What happens to an unfit persons heart rate during exercise?
Goes up more and takes longer to recover
What is glycogen?
Stored glucose
