Dietary Connections

JoVE 10746

Organisms also ingest food in the form of carbohydrates, proteins, and lipids, which also play a role in the glycolysis pathway.



Carbohydrates, Proteins, and Lipids

Carbohydrates—chains of many simple sugars—are first broken down into smaller units and fed into the glycolysis pathway, where they are then broken down into pyruvate. For example,…

The Citric Acid Cycle

JoVE 10741

The citric acid cycle is a closed loop of reactions that occur in the mitochondrial matrix, including redox, dehydration, hydration, and decarboxylation reactions. Its name is derived from the intermediate compound, citric acid. As the steps were first identified by Hans Krebs, this aerobic pathway is also known as the Krebs cycle, which over a series of eight enzymatic steps, is critical in…

Pyruvate Oxidation

JoVE 10740

After glycolysis, the charged pyruvate molecules enter the mitochondria via active transport and undergo three enzymatic reactions. These reactions ensure that pyruvate can enter the next metabolic pathway so that energy stored in the pyruvate molecules can be harnessed by the cells.



First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and…

Biological Catalysts

All living organisms continuously perform numerous biochemical reactions to sustain their presence. Most of these reactions require an input of energy to start, which is called the activation energy. Catalysts are chemicals that lower the activation energy. Even though catalysts facilitate a chemical reaction, they are not consumed by it. This means a catalyst …

The ATP Bioluminescence Assay

JoVE 5653

In fireflies, the luciferase enzyme converts a compound called luciferin into oxyluciferin, and produces light or “luminescence” as a result. This reaction requires energy derived from ATP in order to proceed, so researchers have exploited the luciferase-luciferin interaction to gauge ATP levels in cells. Given ATP’s role as the cell’s currency of…

An Introduction to Cell Metabolism

JoVE 5652

In cells, critical molecules are either built by joining together individual units like amino acids or nucleotides, or broken down into smaller components. Respectively, the reactions responsible for this are referred to as anabolic and catabolic. These reactions require or produce energy typically in the form of a “high-energy” molecule called ATP. Together,…
