Final answer:
The organisms capable of carrying out cellular respiration in the thioglycolate tube cultures are the facultative anaerobes in tube C and the obligate aerobes in tube A, as both rely on oxygen to perform aerobic cellular respiration.
Step-by-step explanation:
The tube that contains organisms capable of carrying out cellular respiration will be the one where we have observed growth in the presence of oxygen, as oxygen is essential for aerobic cellular respiration. In this case, we are given a scenario with different bacterial growth patterns in thioglycolate tube cultures, which have been used to illustrate the oxygen requirements of various bacteria. The facultative anaerobes in tube C and the obligate aerobes in tube A are capable of aerobic cellular respiration. Facultative anaerobes can perform cellular respiration in the presence of oxygen, and revert to anaerobic respiration or fermentation in its absence. Obligate aerobes require oxygen for their metabolism and hence are also capable of cellular respiration. Therefore, the organisms in tubes A and C can carry out cellular respiration.
It's important to note that while the other types of bacteria grow under different conditions, such as the obligate anaerobes which are found at the bottom of tube B, the microaerophiles in the 'Goldilocks' culture of tube E, and the aerotolerant anaerobes in tube D, it is the obligate aerobes and facultative anaerobes that rely on oxygen for cellular respiration.
