Anaerobic condition refers to an environmental condition where oxygen is absent. In case of Electron Transport System (ETS) and ATP production, oxygen acts as the final acceptor of electrons. As oxygen is a reactant in ETS and ATP production, unavailability of oxygen can cause no oxidation of the coenzymes or the carriers such as NAPH and FADH2 and no ATP will be produced. Thus, both Electron Transport System and ATP production will stop in the absence of oxygen.
Since each glucose molecule produces two acetyl-CoA molecules, the Krebs cycle must be completed twice to produce the four CO2, six NADH, two FADH2, and two ATPs.
- Catabolic reactions occur within cells during cellular respiration. It is a biochemical process by which waste materials are removed and nutrients are broken down to generate energy, which is then stored in the form of ATP. The process of aerobic respiration needs oxygen.
- The Krebs cycle, also known as the citric acid cycle, is the last step of oxidation for amino acids, lipids, and glucose.
- Other than glucose, many animals rely on other substances for energy.
- Protein's metabolic byproduct, amino acids, are deaminated and converted to pyruvate and other Krebs cycle intermediates.
- They begin the cycle and are broken down, for example. On deamination, alanine turns into pyruvate, glutamate into -ketoglutarate, and aspartate into oxaloacetate.
- Acetyl CoA is created when fatty acids are -oxidized and enters the Krebs cycle. It is the primary mechanism through which cells produce ATP. Complete nutrient oxidation results in the production of a significant amount of energy.

Answer:
Apple tree and grass are producers, mushroom and bacteria are decomposers, and everything else are consumers. The bear is herbivore I believe, the rabbit is as well to my understanding. The pig is omnivore and lion is carnivore.
Explanation:
Starting with producers, most plants are producers. They photosynthesize to make their own food (glucose). Decomposers break things down like dead animals. Carnivores eat only meat, which is what a lion does. It eats no plants. The pig is an omnivore, meaning that it eats both meat AND plants. Lastly, the bear and rabbit are herbivores meaning that they only eat plants. I always remember it as "HERBivore which sounds like HERBS which are plants" Hope this helps!
Clean or green energy helps in releasing lesser air pollution and lesser carbon dioxide. That contributes in lowing down global warming and subsequent disasters like tsunami because of glacier melting , more unexpected climate changes like unexpected long-period storms, flood, typhoons, etc.
Hope this would help.
