33
Q

Site of Cyanide
A. Cytochrome oxidase
B. ADP phosphorylation
C. NADH-CoQ reductase

A

A. Cytochrome oxidase

34
Q

Effect of Cyanide

A. All intermediates before and including cyt a will be in the reduced state; all intermediates after and including cyt c1 will be oxidized states. Blocks site lll
B. Blocks transfer of electrons to O2. Blocks at site IV
C. Inhibits entry of ADP into mitochondria and ATP export. Stop electron transport because of lack of ADP. Inside, all ADP is converted to ATP

A

B. Blocks transfer of electrons to O2. Blocks at site IV

35
Q

Site of Antimycin

A. ADP phosphorylation
B. ADP-ATP transporter
C. Electron transfer from cyt b to cyt c1

A

C. Electron transfer from cyt b to cyt c1

36
Q

Effect of Antimycin

A. All intermediates before and including cyt a will be in the reduced state; all intermediates after and including cyt c1 will be oxidized

B. Blocks phosphorylation of ADP. Does not inhibit uncouples oxidations

C. Blocks oxidation of NADH (site l). NADH will be reduced; Substrates such as succinate that enter via FADH will still be oxidized and make 2 ATPs/mol
