Description
Substrate types in SUIT protocols are types of reduced substrates feeding electrons into the electron transfer system (ETS) at different levels of mitochondrial pathways. Substrates of type 1 may be artificial electron donors essentially bypassing the ETS and feeding electrons directly into the terminal electron acceptor, cytochrome c oxidase (CIV) or alternative oxidases (single enzymatic step). Substrates of type 2 feed electrons into Complex III (CIII) with further electron transfer downstream of the Q-junction. Substrates of type 3 feed electrons into respiratory complexes directly upstream of the Q-junction, whereas substrates of type 4 feed electrons into dehydrogenases and enzyme systems upstream of the type 3 pathway level.

Substrate types on different pathway levels
- Substrate types on the pathway level of converging NADH- and FADH2-linked dehydrogenases, including the TCA cycle and beta-oxidation:
- N: NADH-linked substrates (CI-linked)
- F: FADH2-linked substrates (FAO)
- Substrate types on the pathway level of electron transfer complexes converging at the Q-junction:
- S: Succinate (CII-linked)
- Gp: Glycerophosphate (CGpDH-linked)
- Substrate types on the single step level of cytochrome c oxidase (CIV), the terminal step in the aerobic electron transfer system:
