Explanation:

Exp:C In succulent plants, at night stomata are open and ${CO}_{2}$ is fixed into organic acid therefore, at night there is no net ${CO}_{2}$ evolved.
Hence, value of R.Q. is zero.

283801 More ${CO}_{2}$ is evolved than the volume of oxygen consumed when the respiratory substrate is:

1 fat

2 sucrose

4 organic acid

Explanation:

Exp:D More ${CO}_{2}$ is evolved than the volume of oxygen consumed when the respiratory substrate is organic acid. The organic acid consume less oxygen due to its adequate presence and give R.Q. more than one.
