Two fermenters, P and Q, were producing mycoprotein under the same controlled conditions.
The sugar supply to fermenter P then stopped, but its oxygen supply continued.
The oxygen supply to fermenter Q then stopped, but its sugar supply continued.
No other conditions changed.
Which describes the expected effect of these supply failures?
Mycoprotein output decreases from fermenter P only.
Mycoprotein output does not decrease from either fermenter.
Mycoprotein output decreases from both fermenter P and fermenter Q.
Mycoprotein output decreases from fermenter Q only.
