Description
Categories of SUIT protocols group SUIT protocols according to all substrate types involved in a protocol (F, N, S, Gp), independent of the sequence of titrations of substrates and inhibitors which define the Electron-transfer-pathway states. The N-type substrates are listed in parentheses, independent of the sequence of titrations. ROX states may or may not be included in a SUIT protocol, which does not change its category. Similarly, the CIV assay may or may not be added at the end of a SUIT protocol, without effect on the category of a SUIT protocol.
- F - ET-pathway-level 5: FADH2-linked substrates (FAO) with obligatory support by the N-linked pathway.
- N - ET-pathway-level 4: NADH-linked substrates (CI-linked).
- S - ET-pathway-level 3: Succinate (CII-linked).
- Gp - ET-pathway-level 3: Glycerophosphate (CGpDH-linked).
- Y(X)- In the SUIT general protocols Y makes reference to the ET-pathway state and X to the combination os substrates added for the corresponding pathway.

Abstract: The complexity of SUIT protocols is primarily determined by the large number of Electron transfer-pathway states and fuel substrates involved, compared to only three well defined coupling-control states. Whereas the SUIT protocol names specify all sequential steps in a SUIT protocol, the categories of SUIT protocols reduce this diversity to a list of substrate types involved.

Towards a library of SUIT protocols
- At the present stage of development of the Library of SUIT protocols as part of the MitoFit Quality Control System, the substrate types linked to five ET-pathway types are considered.
- F-junction on the pathway level of converging FADH2- and NADH-linked dehydrogenases, including beta-oxidationthe and segments of the TCA cycle.
- N-junction on the pathway level of NADH-linked dehydrogenases, including the TCA cycle.
- Q-junction on the pathway level of electron transfer complexes converging at the Q-junction (S and Gp).
- Tm on the single step level of cytochrome c oxidase (CIV), the terminal step in the aerobic electron transfer-pathway. Tm can be included or excluded at the end of a SUIT protocol. To simplify the categorization, Tm is not considered in this system of SUIT protocols.
- At the present stage of development of the Library of SUIT protocols as part of the MitoFit Quality Control System, the substrate types linked to five ET-pathway types are considered.

Multiple ET pathways without N
- Addition of malate alone (M without P or G) is not considered as substrate type N. However, high mt-malic enzyme activity requires a change of this concept, when M alone represents an ET-pathway ccompetent substrate state. Low concentration of M may be used to support FAO, whereas a higher concentration of M may be required for N-junction respiratory capacity to override FAO capacity; this needs corresponding kinetic analyses (SUIT test protocols).
