Question

Question 2 Consider the redox reaction describing the electron transfer of two of the cytochromes in the electron transport chain. Answer the following Not yet answered questions based on the forward direction of the reaction as shown below (answers may be used more than once). cytochrome c(Fe)+ cytochrome a(Fe)cytochrome c(Fe)+ cytochrome a(Fe) Points out of 1.00 Flag question O cyto c(Fe) O cyto a(Fe2+) Which endproduct, cyto c(Fe or cyto a(Fe), lost electrons from the reaction? cyto c(Fe2) O cyto a(Fe3+) Which reactant, cyto c(Fe) or cyto a(Fe"), becomes reduced from the chemical reaction? O cyto c(Fe+) O cyto a(Fe3+) Is cyto c(Fe ) or cyto a(Fe the reducing agent?

Explanation / Answer

ANSWERS-

1.cyto c(Fe 3+),because cytochrome c(Fe 3+) only lost electrons,then only its charge became from +2 to +3.

2.cyto a(Fe 3+), because reduced means gain of the electron that is the loss of charge.

3.cyto c(Fe 2+), because reducing agent means that cytochrome will reduce the other cytochrome and get oxidized itself.
