The third option, Light intensity has an impact on the rate of photosynthesis.
Explanation:
Light is a limiting factor at low intensity. Thus the rate of photosynthesis increases with an increase in light intensity. High light intensities affect the rate of photosynthesis. It increases the temperature of the leaves. Therefore, rate of transpiration increases
Epinephrine triggers a direct signal transduction pathway.
I know this because when epinephrine binds to it's receptor example on a muscle cell,this is known as a type of G protein -coupled receptor,signal transduction cascade is triggered and this involves the production of a second messenger molecule cyclic AMP(cAMP).
Epinephrine also know as Adrenaline or sus-phrine.
It is a vasoconstrictor,broncho dilator and a sympathetic stimulant.
It constricts the peripheral abdominal organs as well as a stimulating the heart beat thereby raising the blood pressure,it also relaxes the spasms of the bronchial muscles thereby promoting ventilation of the lungs.
