Module 1 Flashcards
A pathway that involves both anabolic and catabolic portions
Amphibolic Pathway
A process in which complex molecules are generated from simpler precursors
Anabolism
A process in which complex molecules are broken down into simpler precursors
Catabolism
organisms that obtain energy by the oxidation of electron donors in their environment
Chemotroph
A process that has an overall positive energy change (non-spontaneous process)
Endergonic
A measurement of the randomness or disorder of a system
Entropy
A process that has an overall negative free energy change (spontaneous process)
Exergonic
Series of chemical reactions occurring within a cell. The pathway may be linear, branched, or circular
Metabolic Pathway
The tendency of a phosphorylated molecule to undergo hydrolysis
Phosphoryl-Transfer Potential
Organisms capable of synthesizing their own food from inorganic substances while using light as an energy source
Phototroph
A molecule generated in an enzymatic reaction
Product
One molecule becomes reduced by gaining electrons donated by another molecule that becomes oxidized.
Redox Reaction
A reactant in an enzymatic reaction
Substrate
A metabolically required substance that cannot be synthesized by the organism and must be obtained from the diet.
Vitamin
