topic 7 - respiration Flashcards
1
Q
how does respiration produce ATP?
A
in cellular respiration, glucose and oxygen react to form ATP
2
Q
what is the role of ATP?
A
it’s the source of energy for use and storage at the cellular level
3
Q
what is aerobic respiration?
A
respiration that takes place in the presence of oxygen
4
Q
what is anaerobic respiration?
A
respiration that doesn’t use oxygen to occur
5
Q
aerobic respiration word equation
A
glucose + oxygen → carbon dioxide + water + ATP
6
Q
aerobic symbol equation
A
C6H12O6 + 6O2 → 6CO2 + 6H2O
7
Q
anaerobic word equation in animals
A
Glucose → lactic acid
8
Q
anaerobic word equation in plants
A
Glucose → ethanol + carbon dioxide + ATP
9
Q
test for the evolution of CO2 and heat from respiring seeds or other living organisms
A
- add hydrogencarbonate indicator solution into 4 separate test tube
- add a mesh layer to each test tube and add live maggots, dead peas, live peas and plastic beads to each test tube.
- place a rubber bung over each test tube
- record the original colour of the hydrogen carbonate indicator
- leave for an hour and then record the colour again
- if it remains red, the solution is neutral. if it turns yellow, the solution is more acidic as CO2 has been released - indicator of respiration
