The correct answer is B. Electron transport.
The electron transport chain is the terminal step of aerobic respiration. It occurs on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ are produced during glycolysis and Krebs cycle. When NADH and FADH₂ move along electron transport chains, high-energy electrons are released from NADH and FADH₂ produce ATP. The final electron acceptor in the process is free oxygen. Each NADH produces 3 ATP and each FADH₂ produces 2 ATP. Therefore, a total of 32 ATP molecules are generated in electron transport. Therefore, the electron transport system releases a lots of energy for cheetah to run fast.
Scientists carry out several researches to understand the cause and reason behind the natural phenomena happening around us. While carrying out an experiment, the scientist need to refer to various research papers and research articles to plan and follow the protocol of the experiment accordingly.
Going through the background studies lead to greater insight and knowledge about the subject. It broadens our mind and way of thinking. It makes us more logical and precise towards our work.
Normally, the concentration of solutes in our brain cells would be the same as the concentration of the cerebrospinal fluid. Thus, they form an isotonic solution.
