Many factors affect cellular respiration in organisms:

$FACTORS AFFECTING CELLULAR RESPIRATION$ $bb("FACTORS AFFECTING CELLULAR RESPIRATION")$

1. TEMPERATURE:

2. OXYGEN:

3. $C O_{2}$ $CO_2$ {Indirectly affect respiration}:

If $C O_{2}$ $CO_2$ concentration increases rate of respiration decreases in plants
Increased concentration of $C O_{2}$ $CO_2$ concentration{>1%} stimulate ABA release and thus stomata become closed and hence reduces oxygen availability.

4. LIGHT:

Indirectly affect respiration
Rate of respiration increase in light intensity
In twilight $\to$ $rarr$ morning and evening rate of photosynthesis and
respiration will be 1:1 $\to$ $rarr$ If it occur due to light it is called
light compensation point in such time there is no exchange of gases between plants and atmosphere

5. Hormones :

6. Injury disease and wounds $\to$ $to$ enhance respiration

7. Respiratory Inhibitors:

cyanides, CO, Amytal, Azide, Dinitrophenol.
