U5T7 – Anaerobic Respiration & Respiration Experiments

Is this the correct equation for anaerobic respiration in animal cells? : Glucose → Carbon Dioxide + Lactic Acid

Is this the correct equation for anaerobic respiration in yeast cells? : Glucose → Carbon Dioxide + Water + Ethanol

In which stage of respiration is oxygen required?

If oxygen isn't available, which substance cannot be regenerated in high enough amounts to keep the system running?

In the absence of oxygen as the final electron acceptor, some processes of aerobic respiration cannot occur. Some of the processes however can continue, which is the last stage that can still function?

The diagram above represents anaerobic respiration in which type of organism?

The diagram represents anaerobic respiration, name substance 'X'.

The diagram represents anaerobic respiration, name substance 'W'.

The diagram represents anaerobic respiration, name substance 'Y'.

The diagram represents anaerobic respiration, name substance 'Z'.

The diagram above shows anaerobic respiration in which type of organism?

The diagram above shows one form of anaerobic respiration, name molecule 'Y'.

The diagram above shows one form of anaerobic respiration, name molecule 'Z'.

Anaerobic respiration allows the regeneration of NAD+ in all organisms, which allows glycolysis to continue. How many ATP's are gained during anaerobic respiration of one glucose molecule?

The above apparatus was left in a water bath until it reached a constant temperature. It was then left for one hour before starting. Why was it left for one hour before starting?

In this investigation, are the yeast respiring anaerobically or aerobically ?

Which direction would the bubble move in the above experiment?

The student found that the coloured liquid moved 1.5 cm in 24 hours. The diameter of the lumen (hole) of the capillary tubing was 1 mm.The volume of a capillary tubing is given by πr²l, where π is 3.14 and l = length. Calculate the volume of gas produced in cm³ hour^-1.
