As an assist to his students back in 1960, microbiologist Donald Nicholson sketched out a big chart of metabolic pathways; he thought it would help them to have it pinned up on a wall for ready ...

The new molecules built via anabolic pathways (macromolecules) are useful for building cell structures and maintaining the cell. Cells constantly adjust the flow of molecules through metabolic ...

All metabolic pathways have to be regulated and controlled to stop the build-up of an end product that isn’t needed. The cell can control a metabolic pathway by the presence or absence of a ...

Enzymes control metabolic pathways. The enzymes change the substrate at each step in the metabolic pathway in order to get the final product at the end. There are different types of metabolic ...
