Answer:
This question lacks options, options are:
A) ATP
B) NADP
C) Pryuvate
D) glucose
E) acetyl-CoA.
The correct answer is C) Pyruvate.
Explanation:
Pyruvate is a very important compound for the cell since it is a key substrate for energy production and glucose synthesis (neo-glycogenesis), that is, pyruvate is the end product of glucose breakdown in glycolysis. Before entering the mitochondria, it can be converted to lactate, through an anaerobic reaction (in the absence or under oxygen supply) of low performance in energy production, when the main pathway is interfered with. It can also be converted to the amino acid alanine. Within the mitochondria, it can be transformed, by pyruvate dehydrogenase (PDH), into acetyl-coenzyme A (acetyl-CoA), the entry point (substrate) of the Krebs cycle. In addition, by means of pyruvate carboxylase, it can be transformed into oxalacetate, which constitutes the first step in neoglycogenesis.
You are correct it is the answer D.!
OH radicals that convert pollutants to less harmful components.
White Blood Cells (WBCs) are the phagocytic cells that engulf the pathogens such as bacteria and fungi. These cells are specialized cells to protect the body from invading bacteria. These also ingest dead cells. These are generally found in the interstitial spaces throughout the body.
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.
