<span>Enzymes are biological catalysts (they are proteins). Enzymes regulate metabolic pathways in the body.
e.g. Digestive enzymes in your stomach speed up the hydrolysis and breakdown of carbohydrates, proteins and fats in the food you consume.</span>
Answer:
The correct answer is - regulation of the heavy metal and their toxicity.
Explanation:
Metallothionein is a group of cysteine-rich, small in size, and highly conserved proteins that bind to various metal ions and regulate their activity or toxicity in transcriptional level.
Metallothionein IIA is one of the metallothioneins that binds to heavy metal and helps cells to be protected from the toxicity of these heavy metals. These proteins are present in almost every eukaryotic organisms virtually. These proteins are highly induced to express highly in the present of heavy metals.
Thus, the correct answer is - regulation of the heavy metal and their toxicity.
Answer:
Xylem,phloem and tissues from vascular systems produce stem
Xylem + phloem+ tissues from vascular systems = stem ( transport systems)
