Atp's Role In Cellular Respiration
1. ATP is made up of ribose, adenine, and phosphate. It is also made in the mitochondria. ATP plays a very critical role for all organisms from the simplest to the most complex. ATP is like a natural fuel source with out it you wouldn’t be living. ATP enables you to move your muscles and they are building blocks for more complex molecules. Nutrient alone aren’t enough for the body and are of a low energy source but to activate all the nutrients to turn it into a high energy you need ATP. ATP powers cellular work by coupling exergonic reactions to endergonic reactions. The cell performs 3 forms of work chemical work, which pushes endergonic reactions, transport work pumps substances across a membrane and mechanical work the contractions of muscle

Cellular respiration is the process of obtaining energy in order to produce ATP. Cells obtain energy for their metabolic reactions. Cellular respiration includes both aerobic and anaerobic processes. Aerobic is when oxygen is consumed as a reactant and an aerobic is without oxygen. There are three phases in cellular respiration glycolysis, Krebs cycle, and the electron transport chain. Glycolysis is the first stage and this occurs in the cytosol. The 6-carbon structure of glucose is broken down and makes 2 pyruvic acids. Along with the formation of 2 ATP and 2 NADH. The Krebs cycle is the second stage the pyruvic acid enters the mitochondria the is oxidized to form acetyl CoA this breaks down the glucose to carbon dioxide. The steps of both glycolysis and the Krebs cycle are redox reactions that transfer electrons from substrate to nad+ forms NADH. The third stage is the electron transport chain it accepts electron from the broken down products of the last two stages. The final acceptor is oxygen at this stage. The smaller amount of ATP is formed by glycolysis and the kreb cycle by a mechanism called substrate level phosphorylation. For each glucose that is degraded to a carbon and water by respiration the cell makes 32
