Doctor Thomas Nuhse explains that enzymes are proteins in a cell that perform the cell's chemistry.
Enzymes are basically a group of proteins that do chemistry in the cell. That means that they can either construct materials, they put two molecules together to build something useful. For example, all the material that our cells are made of are essentially made by enzymes. Some enzymes are responsible for degrading stuff - so the food that we eat is broken down into smaller units that our cells can use, and that again is something that is done by enzymes.

Doctor Thomas Nuhse explains that proteins are the molecules in cells that perform the key functions of the cell. They are the building bricks of the cell.
Doctor Thomas Nuhse explains that kinases are enzymes that are specialized for attaching a phosphate group to another protein.
1301. Protein-protein Interactions
Doctor Thomas Nuhse describes the process by which proteins interact and work together to produce an outcome.
Doctor Thomas Nuhse explains that phosphorylation is the process by which a phosphate is added to a protein to produce a change in that protein.
1303. Mass Spectrometry
Doctor Thomas Nuhse explains that mass spectrometry is a technique for measuring the mass of molecules, which therefore allows researchers to identify molecules.
1021. Pathways, To the nucleus
In this section learn that many signaling pathways ultimately pass messages to the nucleus of a cell.
16341. Concept 15: DNA and proteins are key molecules of the cell nucleus.
DNA and protein are candidates for transmitting hereditary information.
Professor Tom O'Dell defines phosphorylation - the addition of a phosphate group to a protein molecule to regulate gene function.
15268. Designing bacteria, François Jacob
François Jacob talks about designing bacteria.
1022. Pathways, Inside the nucleus
In this section learn that an activated protein is transported into the nucleus through a pore in the nuclear membrane.
