<span>Oxygen is required and is used to break down nutrients , like glucose sugar they ( nutrients) are later broken down to generate ATP (energy) carbon dioxide & water . organisms can use cellular respiration including bacteria , animals, plants and fungi.

Answer:
2.2.1 O is the enzyme and N is the ligand.
2.2.2 In the figure, the enzyme shows lytic activity by generating two products like digestive enzymes.
2.2.3 Enzymes are indispensable for signal transduction and cell regulation, often via kinases and phosphatases. They also generate movement, with myosin hydrolyzing ATP to generate muscle contraction.
<span>This is a positive feedback. These episodes make the next glacial period even more severe and long-lasting than the one prior. This is due to the reflectance of the surface of the land having a positive relationship with how much energy is absorbed: as the reflectance increases, absorption decreases, and the glacial period increases in severity.</span>
Explanation:
i believe it was the fact that although organisms were similar in appearance,they weren't always closely related?
