When `CO_(2)` concentration in blood increases breathing becomes

Options

A. shallower and slow
B. there is no effect on breathing
C. slow and deep
D. faster and deeper.

Answer

D

Explanation

When `CO_(2)` concentration in blood increases, breathing becomes faster and deeper. The effect of rising `CO_(2)` concentration is due to decrease in affinity of `Hb` for `O_(2)`. Thus, the `CO_(2)` released in the tissues accelrates the delivery of `CO_(2)` (called Bohr effect). due to which breathing becomes faster and deeper.
