Chapter 5 Flashcards
The sum of all chemical
reactions in an organism
Metabolism:
Uses energy and building blocks
to build large molecules
Anabolism:
Provides energy and building
blocks for anabolism.
Catabolism:
is a sequence of enzymatically
catalyzed chemical reactions in a cell.
metabolic pathway
states that chemical reactions can occur when
atoms, ions, and molecules collide
Collision Theory
needed to disrupt
electronic configurations
Activation energy
is the frequency of collisions
with enough energy to bring about a reaction.
Reaction rate
Controls amount of
substance produced by
a cell
Feedback Inhibition
removal of e-
Oxidation
gain of e-
Reduction
2 types of phosphorylation
Substrate level
phosphorylation
Oxidative
phosphorylation:
Formed by series of electron carriers
(cytochromes)
chemiosmosis, pmf generates energy via
oxidative
phosphorylation
uses of fermentation
spoilage of food by microorganisms (general use)
process that produces alcoholic beverages
large-scale microbial process occurring with or without
air (common definition used in industry)
use same organic
compound as energy source and carbon source.
Most medically important bacteria.
Chemoheterotrophs
