redox rxn

redox rxn allow the controlled transfer of energy from …. to….

glucose to ATP

redox rxn are important to the processes of cellular respiration bc they allow the controlled transfer of energy (exergonic reactions) to an endergonic reaction to store the energy

redox reactions invovle the transfer of electrons from one molecule to another

Oxidation

loss of electrons

reduction

gain of electrons

OIL RIG

oxidation is loss

reduction is gain

Reducing agent

the molecule that donates the electrons

the molecule that accepts the electrons

the oxidizing agent

In the body… acts as a key electron carrier in redox reactions

NAD+

NAD+ with the help of an enzyme can grab a proton plus e- and pass it to a NAD+ to become NADH

When going from NAD+ to NADH we are … the molecule. And we are storing some energy by adding p plus e to the molecule.

reducing bc it is gaining an electron

When NADH loses an electron to become NAD+ it is … and some other molecule will be ….

Oxidized (losses e) reduced (gain e )

NADH is a carrier for

energy

Redox (oxidation-reduction) reactions are the driving force of cellular respiration, transferring energy from … to ,….

glucose ATP
