degraded
broken down
metabolic processes are associated with chemical reactions such
as...
redox reactions, dehydration condensation reactions, dehydration
reactions, and hydrolysis reactions
,redox reactions (oxidation-reduction reactions)
involve the transfer of elections
the first step involved in redox reactions (oxidative-reduction
reactions) is...
the oxidation step in which an electron (or hydrogen atom) is lost
from a substrate
the second step involved in redox reactions (oxidative-reduction
reactions) is...
the lost electron is transferred to another substrate (which is called
reduction)
Substrate
a molecule which an enzyme acts upon
reduction
referring to the fact that the charge is reduced because you are
adding an electron
OIL RIG
Oxidation Is Loss, Reduction Is Gain (of electrons)
an example of a redox reaction
Methane and Oxygen become Carbon Dioxide and Water. In this
methane becomes oxidized (loses electrons) and oxygen is reduced
(gains electrons). This releases energy into the surroundings
dehydration condensation reaction
occurs when two or more monomers are joined together and a
molecule of water (or other small molecules) is/are lost. this process
requires an input of energy
other small molecules that could be lost in a dehydration
condensation reaction
hydrogen chloride, methanol, or acetic acid
, an example of a dehydration condensation reaction
the formation of a triglyceride which is the joining of a glycerol and
a fatty acid, results in the loss of water.
in this, 3 separate dehydration reactions occur to get the final
triglyceride molecules so there is a release (loss) of 3 water
molecules
dehydration condensation reactions can occur in these types of cells
adipocyte or fat cells
dehydration reaction
also used to join the monomers in order to form polysaccharides and
a molecule of water is lost
(T/F) dehydration reactions are a specific subset of dehydration
condensation reactions
TRUE
An example of a dehydration reaction
sucrose synthesis. disaccharide sucrose is synthesized from two
monosaccharides (glucose and fructose) which results in water
being released.
this happens often in plants through photosynthesis
sucrose synthesis
sucrose is formed by the joining together of the monomeric sugars,
glucose and fructose. During the reaction, a molecule of water is
given off
