When you look at a picture of a dog and then correctly identify it, what have you done in your conscious mind?
ivolga24 [154]

Answer:

Perception

Explanation:

When a person is given some sensory information, the receptors of sense organs sense the given information and send it to the brain which analyses and interpret it to make the required response.  

Likewise, when someone is given a picture of a dog, the photoreceptors see the image and send the sensory information to the brain. The brain analyzes the sent visual information and identifies it as a dog based on previous experience.

The process of sensing the information followed by its analysis and interpretation by the brain to develop the required understanding is called perception.

Describe the biosynthetic pathway that produces catecholamines such as norepinephrine and epinephrine from amino acid precursors
Dmitry [639]

Answer:

Tyrosine and phenylalanine are amino acids required for the synthesis of catecholamines

Explanation:

The catecholamines are hormones composed of a catechol ring group (benzene) and an amine lateral chain. One of the most common catecholamines is the neurotransmitter norepinephrine (noradrenaline). The biosynthesis pathway of the norepinephrine hormone includes the following steps: 1-tyrosine hydroxylase produces L-DOPA from tyrosine, 2-L-DOPA is subsequently tranformed into dopamine by the L-amino acid decarboxylase, and finally, 3-this chemical precursor is converted into norepinephrine by the action of the dopamine β-hydroxylase.  

Phenylketonuria is a congenital metabolic disease associated with a decrease in the metabolism of phenylalanine (Phe), which is an amino acid residue that acts as a precursor of different catecholamines including dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline). Dietary restriction of tyrosine and phenylalanine is the most common treatment against phenylketonuria.
