In Mass Spectrometry, a Molecule Is Ionized and Its Migration

question 20

Multiple Choice

In mass spectrometry, a molecule is ionized and its migration rate in an electrical field is determined.What information does the migration rate tell about the molecule?

• A)It indicates mass because small molecules migrate more rapidly than larger molecules.
• B)It indicates electrical charge because negatively charged molecules migrate more rapidly than positively charged molecules.
• C)It indicates the solubility of the molecule because insoluble molecules form aggregates and migrate much slower than soluble molecules.
• D)It indicates the relative abundance of the molecules in the sample.
• E)It indicates the complexity of the proteome because greater proteome diversity takes a longer time to process.

Definitions:

Process Manufacturing

A production method used in industries such as chemical, food, and pharmaceuticals, where goods are produced in continuous, batch processes rather than discrete units.

Unique Items

Products or goods that are distinct in characteristics or are produced in small quantities, making them rare or uncommon.

Equivalent Units

A concept in cost accounting used to allocate costs to partially completed goods, measuring them in terms of the amount of finished goods they represent.

Process Costing

An accounting methodology used to allocate costs to products in industries where the production process is continuous and units are indistinguishable from one another.
