Complex II contains five prosthetic groups and four different protein subunits;
a. Subunits A and B extend into the matrix; they contain three 2Fe-2S centers, bound FAD, and a
binding site for the substrate, succinate
b. Subunits C and D are integral membrane proteins, contain a heme group, heme b, and a binding
site for ubiquinone,

Autosomal Recessive Traits

Autosomal recessive traits normally appear with equal frequency in both sexes.

The trait seems to skip generations.

When both parents are heterozygous, approximately one-fourth of the offspring are expected to express the trait.

Recessive traits appear more frequently among the offspring of consanguineous matings.

Example - Tay–Sachs disease, sickle cell anemia, cystic fibrosis, PKU

Type-B ARRs are activated by phosphorylation, which enables them to regulate the transcription of a set of target genes for cytokinin response, and type-A ARRs
