DownloadWhat is a cofactor? And give a general example.
Flip card
A cofactor is a small chemical component that assists enzymes during catalysis reactions. A general example of a cofactor is metal ions.
Define anabolism.
Flip card
Anabolism is the process of building up or biosynthesis of macromolecules from small molecular units into much larger complexes.
In order to convert proteins into amino acids which metabolic process would be active?
Flip card
Catabolism would be active as proteins are made up of amino acids. Therefore, the process described (proteins into amino acids) is the breakdown, or catabolism, of protein.
Describe the energy transfer process relative to both ATP and ADP.
Flip card
ATP has the energy (phosphate group) to donate while ADP can accept energy in the form of a phosphate group. Thus, ATP can be reduced (ATP ⟶ ADP + Pi) while ADP can be built into ATP (ADP + Pi ⟶ ATP).
From what source do chemotrophs acquire energy?
Flip card
Chemotrophs acquire energy from preformed chemicals found in the environment.
An organism that derives its energy by removing electrons from elemental sulfur would be classified as a __________?
Flip card
Lithotroph.
This phosphorylation process occurs in the mitochondria of chemotropic eukaryotes.
Flip card
Oxidative phosphorylation.
The catabolism of a single molecule of glucose goes through what 3 distinct transitions?
Flip card
The breakdown of glucose goes through (1) Glycolysis, then (2) Fermentation or Respiration, and finally through (3) the electron transport chain (ETC).
