Answer:
D. Not all living things engage in the Krebs cycle
Explanation:
The Krebs Cycle, or also known as the citric acid cycle as it is the first substance to be formed during the cycle, is one of the stages of the cellular respiration process, only of aerobic organisms, occurring within the mitochondria of eukaryotic cells. The krebs cycle is the second stage of cellular respiration, also called the aerobic stage, as it occurs in the presence of oxygen. With this we can conclude that not all living beings engage in the Krebs cycle, since anaerobic organisms do not survive in the presence of oxygen.
