Description
Abbreviation: NS(P)
Reference: A »Versions
- SUIT-category: NS(P)
- SUIT protocol pattern: diametral 1S;2D;3P;4Rot;5Ama
Step | State | Pathway | Q-junction | Comment - Events (E) and Marks (M) |
---|---|---|---|---|
1S | SL | S | CII | SL or S_L: Succinate, S-LEAK respiration, SL
Succinate, S ( type S-pathway to Q). Template:SUIT L n |
2D | SP | S | CII | 1S;2D
Succinate, S ( type S-pathway to Q). OXPHOS capacity P (with saturating [ADP]), active OXPHOS state. |
3P | NSP | NS | CI&II | 1S;2D;3P
NADH-linked substrates (type N-pathway to Q). & Succinate, S ( type S-pathway to Q). Respiratory stimulation by simultaneous action of type N substrates & succinate, with convergent electron flow in the NS-pathway for reconstitution of TCA cycle function. OXPHOS capacity P (with saturating [ADP]), active OXPHOS state. |
4Rot | SP | S | CII | 1S;2D;3P;4Rot
Succinate, S ( type S-pathway to Q). OXPHOS capacity P (with saturating [ADP]), active OXPHOS state. Succinate pathway control state (S-pathway) after inhibiting CI with rotenone, which also inhibits the F-pathway.
|
6Ama | ROX | Rox is the residual oxygen consumption in the ROX state, due to oxidative side reactions, estimated after addition of antimycin A (inhibitor of CIII). Rox is subtracted from oxygen flux as a baseline for all respiratory states, to obtain mitochondrial respiration (mt). |

Strengths and limitations
- + Contribution of N patway to the NS can be chekcked after the addition of Rot.
- +
- + Reasonable duration of the experiment.
- - Rox may be lower in substrate states earlier in the SUIT protocol. Therefore, this Rox measurement is frequently taken as a methodological control rather than as the final basis of Rox correction of mitochondrial respiration (mt).
- - Careful washing is required after the experiment to avoid carry-over of inhibitors.
- - CIV activity cannot be measured together with the fluorescence.
