A large culture of living bacteria is supplied with glucose in an insulated container. A temperature probe records the temperature of the culture.
Which prediction about the probe reading follows from respiration being exothermic?
The temperature rises only after the bacteria stop respiring.
The temperature stays the same, as all the energy is stored in ATP.
The temperature rises while the bacteria are respiring.
The temperature falls while the bacteria are respiring.
