Microbial Metabolism Flashcards
- it is the buildup and breakdown of nutrients within a cell
- provide energy and create substances that sustain life
Metabolism
Two key players in metabolism
- Enzyme
- Adenosine triphosphate (ATP)
It catalyze reactions for specific molecules
Enzymes
Enzymes catalyze reactions for specific molecules called _____
Substrates
During enzymatic reactions, substrates are transformed into new substances called _______
Products
Enzymes, which are generally proteins, may need other
nonprotein molecules called _______ to work
Cofactors
It includes metal ions
Inorganic cofactors
It includes the electron carriers FAD, NAD+ and NADP+
Organic cofactors (coenzymes)
a molecule that cells use to manage energy needs
Adenosine triphosphate (ATP)
Energy is ______ when the terminal phosphate is ____ from ATP
- released
- split
The chemistry of metabolism can seem overwhelming at first, with ______, or sets of many coordinated reactions, working together toward common goals
pathways
Two general types of Pathways
Catabolic and Anabolic
It break down macromolecules into simple component parts, releasing energy in the process
Catabolic Pathways
It build up macromolecules by combining simpler molecules, using energy in the process
Anabolic Pathways
What links catabolic and anabolic pathways?
Energy
