Concept explainers
Interpretation:
To determine the number of electrons that an electron carrier carries between complex III and IV per trip
Concept introduction:
Electron transport chain is a sequence of biochemical reactions in which electrons and hydrogen atoms from the citric acid cycle are transferred to various intermediate carriers and finally reacts with molecular oxygen to form a water molecule. The reaction of the formation of the water is:
There are four complexes associated with the electron transport chain that is present in the inner mitochondrial membrane. The four complexes that help in the electron transfer in the electron transport chain are:
Complex I:
Complex II:
Complex III:
Complex IV:
Cytochrome is a protein that has a heme unit in its structure. The iron present in the heme unit participate in the
