A single-celled eukaryotic organism that is neither a consumer nor a decomposer would most likely be classified in _____.
DedPeter [7]

A single-celled eukaryotic organism that is neither a consumer nor a decomposer would most likely be classified in Kingdom Protista.

Kingdom protista:

  • The classification of a third kingdom, separate from animals and plants was first proposed by John Hogg in 1860 as the kingdom Protista; in 1866 Ernst Haeckel also proposed a third kingdom Protista as "the kingdom of primitive forms".
  • Originally these also included prokaryotes, but with time these were removed to a fourth kingdom Monera.
  • In the popular five-kingdom scheme proposed by Robert Whittaker in 1969, Protista was defined as eukaryotic "organisms which are unicellular or unicellular-colonial and which form no tissues", and the fifth kingdom Fungi was established.
  • In the five-kingdom system of Lynn Margulis, the term protist is reserved for microscopic organisms, while the more inclusive kingdom Protoctista (or protoctists) included certain large multicellular eukaryotes, such as kelp, red algae, and slime molds.
  • Some use the term protist interchangeably with Margulis's protoctist, to encompass both single-celled and multicellular eukaryotes, including those that form specialized tissues but do not fit into any of the other traditional kingdoms.

Which process will be immediately inhibited if cytochrome c is unable to interact with cytochrome c oxidase
bonufazy [111]

Answer:

Electron transfer to from cytochrome c to molecular Oxygen in the process of oxidative phosphorylation

Explanation:

Cytochrome c is a protein which is involved in the electron transport chain for the production of ATP molecules during then process of respiration. It a soluble protein found in the intermembrane space of the mitochondria. It receives electrons from ubiquinone at Complex III of the electron transport chain and transfers this electron to molecular oxygen through its interaction with complex IV or cytochrome c oxidase, reducing molecular oxygen to water.

If the interaction of cytochrome c with cytochrome c oxidase is inhibited, the process of elctron transfer to oxygen will be inhibited and, so ATP synthesis will cease.

Ultimately,  respiration will be inhibited resulting in death of the organism. For example, cyanide inhibits cytochrome c oxidase resulting in death of the organism poisoned with cyanide.
