Which statement about nitric oxide is true?
a. It is a hydrophilic second messenger.
b. It is a hydrophobic autocrine signal.
c. It is a hydrophilic paracrine signal.
d. It is a hydrophilic gas.
e. It is a hydrophobic second messenger.
Homework Answers
Answer : The correct option is E (It is a hydrophobic second messenger.)
Explanation : Nitric oxide (NO) is a hydrophobic gaseous signaling molecules which is synthesized by the enzyme nitric oxide synthase using L-arginine. Nitric oxide and other gaseous molecules such as carbon monoxide and hydrogen sulphide can diffuse through cytosol and across cellular membranes

Nitric oxide (NO) is a gas that decomposes in air, therefore it is usually made when it is needed immediately. The most common use of nitric oxide is as fertilizer. In order to produce nitric oxide, 25 kmol/h of ammonia (NH3) and a stream of oxygen (02), both at 25°C and 1 atm, are fed into a continuous reactor packed with catalyst in which ammonia is completely consumed. The product gas emerges at...
