Anaerobic respiration steps VideoATP \u0026 Respiration: Crash Course Biology #7 anaerobic respiration steps
How does oxygen help in the process of cellular respiration?
Share on Facebook Aerobic respiration is a physiological process that takes place in your body to generate an energy molecule called adenosine-5'-triphosphate, or simply ATP. All of your body's cells rely on ATP for normal functioning. This is especially true as it relates to your musculoskeletal system, which requires a large amount of this molecule to allow for normal movement. There are four main steps during aerobic respiration, each of which contributes to the production of ATP.
Glycolysis The first step in anaerobic respiration steps respiration is glycolysis, which literally means the breakdown of glucose.
This process takes place in the anaerobic respiration steps, which is a jelly-like substance in your cells. During glycolysis, molecules of glucose are broken down to yield four molecules of ATP, two three-carbon molecules called pyruvate and two molecules of nicotinamide adenine dinucleotide, or NADH.
This is because glycolysis actually uses two ATPs during the first phase of the process to generate glyceraldehydephosphate.
Acetyl-CoA The next step in aerobic respiration ajaerobic the formation of acetyl-coenzyme A. This occurs in here mitochondria, which are small energy organelles within your cells. The pyruvate that was created during glycolysis is converted to a two-carbon acetyl group, which then combines with coenzyme A to produce acetyl-coA.
Krebs Cycle The third step in aerobic respiration also takes place in your mitochondria. The acetyl-coA that was produced from pyruvate combines during the Krebs cycle to produce oxaloacetate, thus forming citrate.
Why is oxygen needed in cellular respiration quizlet?
This citrate then undergoes several conversion steps to form the following compounds, in order: isocitrate, alpha ketoglutarate, succinyl-CoA, succinate, fumarate and malate. Chemical energy is therefore generated, and this energy is used to create energy in the form of ATP via the ATP synthase enzyme. Image Credit.]
