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.

Mistakes can happen during DNA replication, and if they are not repaired it can result in a mutation. Certain mutations can lead

polet [3.4K]

Mutations result either from errors in DNA replication or from the damaging effects of mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides. All cells possess DNA-repair enzymes that attempt to minimize the number of mutations that occur

According to the oxygen-hemoglobin dissociation curve, PO2 in the lungs of 100 mm Hg results in Hb being 98% saturated. At high

tatiyna

Answer:

95%.

Explanation:

Oxygen-hemoglobin dissociation curve:

Oxygen-hemoglobin dissociation curve is basically a sigmoid curve which relates between the saturation of oxygen (SO2) and partial pressure of oxygen in blood (PO2). It shows the affinity of oxygen with hemoglobin at different temperature and other factors. In the oxygen-hemoglobin dissociation curve; saturated oxygen is ploted on verticle axis and partial pressure of oxygen in mmHg on the horizontal axis.

Here in the above scenario at the high altitude oxygen is less and at 80 mmHg, Hb would be 95% saturated.
