Carbon dioxide is another byproduct, which is exhaled out of organisms. Aerobic processes in cellular respiration can only occur if oxygen is present. Which pathway produces the most energy from a glucose molecule? In the electron transport chain, exergonic redox processes drive the endergonic reaction in which ATP is produced by phosphorylation of ADP. To prepare for this stage, the pyruvate molecules from glycolysis are converted to a 2-carbon compound called Acetyl CoA. Energy produced: A total of 38 ATPs are produced during aerobic respiration, some of which are lost during the process. Working Scholars® Bringing Tuition-Free College to the Community, *Glycolysis: glucose molecule is broken down to release electrons and create ATP, *ATP, which stores energy for cell functions in the body, Recite the formal definition of aerobic respiration, Provide a step-by-step description of the process of aerobic respiration, Analogy compares another process to aerobic respiration, Analogy discusses the reactants and products of the process, Analogy uses at least three steps to compare to glycolysis, the citric acid cycle and oxidative phosphorylation, Analogy clearly explains the relationship between the chosen process and aerobic respiration. succeed. The oxygens use the electrons as glue to bond with free hydrogens, forming H2O. A. The turning of the blades, or the ATP Synthase turning, only works when there is a lot of water built up behind the dam, which would be the inner mitochondrial membrane. We don't normally equate oxygen and breathing with metabolizing food, yet the latter cannot occur without the former. With each turn of the cycle, the Acetyl CoA is broken down and rebuilt into carbon chains. The process of learning about aerobic respiration via this lesson should prepare you to: To unlock this lesson you must be a Study.com Member. A glucose molecule that is metabolized via aerobic respiration has been completely broken down and released as CO2 by the end of: the citric acid cycle. Question: The cellular respiration process takes place in which cell organelle? How Does Exercise Affect the Rate of Breathing?

While many microorganisms can accomplish this task within their single cell, we larger macroorganisms have evolved body organs dedicated to efficiently obtaining enough oxygen, and eliminating enough carbon dioxide, to undergo enough aerobic respiration to fuel our large, complex selves. Which molecules are the reactants or substrates for aerobic respiration?
