This increase in blood pHpH due to hyperventilation disrupts O2O2 transport by causing the deprotonation of various residues of the hemoglobin protein. With less O2O2 reaching the brain, an individual who is hyperventilating may faint. Because the brain needs O2O2 to produce ATP, the brain temporarily shuts down the one function that demands the most ATP—consciousness. Shutting down consciousness conserves energy and allows the brain to devote its resources to maintaining essential life support functions, such as breathing. When O2O2 transport regains its efficiency, the individual regains consciousness. How would rebreathing exhaled air from a paper bag prevent an individual who is hyperventilating from fainting?

The question is incomplete as it does not have the options which has been provided in the attachment.

1. sudden decrease

2. Respiratory alkalosis

Explanation:

Hyperventilation is a condition caused by the excess removal of the CO₂ from the blood which leads to the decrease in the pCO₂ of the arteries.

This decrease can cause fainting and death of the individual due to the malfunctioning of the body parts, especially the brain.

The decrease in the CO₂ amount of the blood causes the formation of bicarbonate and H⁺ ions which leads to respiratory alkalosis.

Therefore the selected options are correct.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
