Concept explainers
To summarize:
Glycolysis, including where it occurs in a cell if it requires oxygen, the substrate and final product, and the formation of energy containing molecules (ATP, NADH, FADH2).
Concept introduction:
Aerobic respiration occurs in the presence of oxygen and energy is released in the form of ATP (adenosine triphosphate). It occurs in two steps; glycolysis and Kreb’s cycle. In glycolysis, glucose is broken down into pyruvate. This pyruvate is fully oxidized in the mitochondria during Kreb’s cycle. The process of glycolysis was given and described by Embden, Meyerhof, and Parnas. It involves the splitting of one molecule of glucose into two molecules of pyruvic acid or pyruvate. In this process, the energy produced is in the form of ATP and NADH (Nicotinamide adenine dinucleotide).
