Respiration Flashcards
1
Q
What is respiration?
A
the transfer of energy from glucose
2
Q
What is ATP?
A
it stores energy and provides it for the cells
3
Q
What is aerobic respiration?
A
- most efficient
- when lots of oxygen is available
- produces 32 molecules of ATP per molecule of glucose
4
Q
What is the equation for aerobic respiration?
A
glucose + oxygen –> carbon dioxide + water (+ energy)
5
Q
What is anaerobic respiration (humans)?
A
- less efficient
- when oxygen can’t be supplied enough for muscles for aerobic respiration
- only produces 2 molecules of ATP
6
Q
What is the equation for anaerobic respiration (animals)?
A
glucose –> lactic acid (+ energy)
7
Q
What is the equation for anaerobic respiration (plants)?
A
glucose –> ethanol + carbon dioxide (+ energy)
8
Q
Temperature change produced in respiration (experiment)
A
- have two sets of beans (germinating and boiled beans)
- put the beans in two separate flasks
- put a thermometer with cotton wool at the top
- record the temperature daily for a week
9
Q
Temperature change produced in respiration (experiment result)
A
- germinating beans can respire, so the flasks temperature will increase, compared to the control flask
