Hemoglobin is neither an enzyme nor a hormone. Hemoglobin is a protein that carries oxygen and the one that is responsible for the red color of the blood. An enzyme is also a protein that accelerate chemical reactions in the body and a hormone is a protein that regulate body functions. Therefore, hemoglobin is just a protein in the body just like enzymes and hormones.

Is glucagone an enzyme?
No, glucagon is a hormone produced by the pancreas that is involved in regulating blood sugar levels by promoting the breakdown of glycogen into glucose in the liver. It is not an enzyme.
Is secretin an enzyme or a hormone?
Secretin is a hormone, not an enzyme. It is produced by the duodenum in response to the presence of acid in the stomach, and it helps to stimulate the release of bicarbonate-rich pancreatic juices to neutralize the acid entering the small intestine.
What hormone is secreted by the mouth?
Salivary amylase, also known as ptyalin, is an enzyme secreted by the salivary glands in the mouth that helps in the breakdown of carbohydrates in food.
Is leptin an enzyme?
No, leptin is not an enzyme. It is a hormone produced by fat cells that plays a role in regulating energy balance and appetite.
What intracellular substance degrades cAMP and inactivating the response to a hormone?
Phosphodiesterase is the intracellular substance that degrades cAMP, leading to the inactivation of the cellular response to a hormone. This enzyme breaks down cAMP into AMP (adenosine monophosphate), thereby terminating the signal transduction pathway initiated by the hormone.
