Ex plain each step of the TCA cycle

What is the net reaction of the TCA cycle

Why are a cofactors (NAD+ and FADH) used in theTCA cycle

Draw the structure of NAD+

Draw the structure of FADH

Draw the reduction reaction of NAD+

NAD+ can carry 2 e-

Draw the reduction reaction of FAD

FADH can carry 2 e-

How does ATP synthase work

What is the structure of F1

What is the structure of F0

What is the binding change mechanism for ATP synthase

How is the rotation of the c ring of F0 powered

What is the structure of a C subunit in a C ring

How many ATP molecules are produced per 360 degrees rotation

How is ADP and inorganic phosphate transported into the matrix ( through the inner mitochondrial membrane)
