Question

Cyanide resistant respiration is found in:
a. Homo sapiens
b. Brassica
c. Spinacia
d. Bacteria

Answer 1

Hint: In general, the chemical compound cyanide is extracted from the natural substances which are present in a few foods and firm plants such as almonds, cassava, and lima beans. This chemical compound is released from Pits and seeds of normal fruits, just like apricots, apples, and peaches. Such types of fruits may contain substantial quantities of chemicals that are broken down to form cyanide. However, the edible parts of such plants hold many inferior quantities of these chemicals.

Complete answer:
Cyanide-resistant respiration is a process that involves the flow of electrons in the typical mitochondrial electron transportation chain (in both animals and plants) in the duration of aerobic respiration which is congested by the occurrence of cyanides as they prevent the action of cytochrome oxidase.

It is the reason that they are named to be cyanide sensitive respiration. Such type of respiration process is carried out by the Spinacia genus of plants.

The organisms which are categorized under the genus of Homo sapiens, Brassica, Bacteria are not the organisms that can respire under such circumstances. They will die if there is a presence of such a harmful substance, cyanide. In general, the organism of this genus undergoes the process of aerobic and anaerobic respiration.

Hence, the correct answer is option (C).

Note: We can say that a speedily acting, hypothetically noxious chemical compound that can exist in various forms is cyanide. On research, we can say Cyanide is a colorless gas and forms in combination forms. For example, hydrogen cyanide (HCN) or cyanogen chloride ($CNCl$), or a crystal form such as sodium cyanide ($NaCN$) or potassium cyanide ($KCN$). Cyanide is said to have a “bitter almond” smell, but it does not constantly give off an odor, and not everybody can detect this odor.
