    Cellular respiration includes the processes of glycolysis, krebs cycle, and the electron transport chain. Glycolysis is used to convert glucose to produce two pyruvate as well as 4 ATP’s and 2 NADH but uses 2 ATP to have a net product of 2 ATP and 2 NADH. The krebs cycle converts pyruvate to Acetyl CoA, which produces 2 ATP,8 NADH, and 2 FADH’s per glucose molecule. Electron transport Chain is the last and most important step of cellular respiration, it makes ATP with the movement of electrons from high energy to low energy that makes a proton gradient which makes ATP, this cannot occur unless oxygen is present. Fermentation is an anaerobic process in which converts sugars into acids, alcohol, or alcohol. This process occurs in yeast and bacteria as well as muscle cells that have no oxygen left. In yeast fermentation produces ethyl alcohol and carbon dioxide from glucose and fructose. Fermentation in bacteria cells the process of fermentation produces ethanol, while in human muscle cells fermentation produces lactic acid in cells that have a short…

    Metabolism explains how the cells in the body use nutrients to meet its needs. Cells may start with small, simple compounds and use them as building blocks to form larger, more complex structures (anabolism). These anabolic reactions involve doing work and so require energy. Alternatively, cells may break down large compounds into smaller ones (catabolism). Catabolic reactions usually release energy. Determine whether the following reactions are anabolic or catabolic. Indicate whether each of the following reactions is anabolic or catabolic.…
