Respiration Flashcards
Where does respiration occur
In the mitochondria
What type of reaction is respiration
Metabolic
Specifically a catabolic
What is the equation for respiration
Oxygen + glucose
——->
Co2 + water + ATP
Why do people breathe heavily after exercise
To repay the oxygen debt
Oxygen is needed to break down the lactate build up
How many ATP are made in anaerobic respiration?
2
What is the respiratory rate?
Rate an organism converts glucose to co2 + water
How do you calculate the respiratory rate
Measuring the organism’s rate of oxygen consumption
In a respirometer experiment, what happens to the coloured dye?
If organism respires,
Oxygen moves up,
Causes change in pressure,
Coloured dye moves towards it
What the the equation for the respiratory quotient
RQ =
Volume oxygen taken in
Which respiratory substrate(s) are aerobic
Lipids
Proteins
Carbohydrates
During anaerobic respiration, how is glycolysis able to continue?
When pyruvate is converted to lactate, NADH is regenerated to NAD+
In a respirometer experiment, why is there a syringe?
To draw the fluid back
This allows you to do the test again (it resets it)
In a respirometer experiment, why is there a clip above the tube?
Stops movement of air/oxygen in and out the tube
Name 4 respiratory substrates
Glucose
Carbohydrate
Lipid
Protein
Which respiratory substrate(s) are anaerobic
Glucose
