M16: Aerobic Respiration Flashcards
is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
AEROBIC RESPIRATION
is a series of chemical reactions in the mitochondrion where molecules of glucose are broken down to make CO2, water and atp

the synthesis of ATP by phosphorylation of ADP for which energy is obtained by electron transport
OXIDATIVE PHOSPHORYLATION
Also known as the cytochrome oxidase system or the respiratory chain.
ELECTRON TRANSPORT CHAIN
a series of protein complexes and electron carrier molecules that generate ATP.
LOCATION: Embedded in the inner membrane walls of the mitochondria.
ELECTRON TRANSPORT CHAIN
Mediates the transfer of electrons in the electron transport chain.
COENZYME Q

COENZYME Q
Contain mostly phosphorus and some vitamins
Behaves like vitamin K1
COENZYME Q
s a small, water soluble heme protein associated with the inner membrane of the mitochondrion.
CYTOCHROME C
carries one electron between two different electron transport complexes embedded in the inner membrane.
CYTOCHROME C
an essential link in the electron transport chain.
CYTOCHROME C
