Question

A chemosensitive area is situated adjacent to respiratory rhythm centre, which is highly sensitive to ..... and ..... ions?

• A. ${\text{CO}}_2,{\text{H}}^{+}$
• B. ${\text{CO}}_2,\text{OH}{}^{–}$
• C. ${\text{CO}}_2,{\text{O}}_2$
• D. ${\text{O}}_2,{\text{H}}^{+}$

Answer 1

The correct option is A ${\text{CO}}_2,{\text{H}}^{+}$

Answer: (c)

Human beings have a significant ability to maintain and moderate the respiratory rhythm to suit the demands of the body tissues. A chemosensitive area is situated adjacent to the rhythm centre, which is highly sensitive to ${\text{CO}}_2$ ​ and hydrogen ions $\left({\text{H}}^{+}\right)$.
