The two main components of the extracellular matrix are Elastin and Collagen.
The extracellular matrix is an intricate macromolecular network that is found in the extracellular space. The matrix is composed of polysaccharides and very diverse proteins, locally secreted and assembled forming a complex network that surrounds the cells. The matrix is highly developed in connective tissue and its derivatives. The extracellular matrix is formed mainly by proteins, glycosaminoglycans,proteoglycans and glycoproteins, organized in diverse networks that constitute the different tissues. <em>The most abundant proteins are collagen and elastin.</em>
Collagen is a family of very abundant proteins in the body of animals. Collagen molecules can represent 25 to 30 % of all body proteins. Its main mission in the tissues is to form a framework that supports the tissues and that resists the forces of mechanical tension.
The elastin molecules are very close to each other through links between the regions rich in the amino acid lysine. It is an abundant protein in may extracellular matrices and appears as a component of the so called elastic fibers, which are onsoluble aggregates of proteins.

As blood glucose returns to its baseline level, the levels of insulin and glucagon in the blood will stabilize. As the blood glucose levels begin to drop below the base line, the concentration of glucagon hormone increases. while as the blood sugar levels increases above the baseline, the level of insulin hormones increases. Insulin and glucagon work antagonistically to maintain the normal level of glucose in the blood.
The nucleus is the control center of a cell in eukaryotes. It is protected by the nuclear membrane. The nucleus holds all of the cell’s genes, which are segments of DNA, found in the chromosomes.
Answer:
The correct answer is D. MMDA
Explanation:
MMDA stands for 3,4-Methylenedioxymethamphetamine. It is a psychoactive drug and is used as a recreational drug. After taking a dose of this drug it shows its effect in 30-45 minutes. People taking these drugs produce a feeling of euphoria and loving worth due to which they feel to hug each other again and again.
It also increases body temperature by making the release of many neurotransmitters in the body which results in vasoconstriction and as a result heat production occurs and heat dissipation is reduced. It also leads to thirst, sleepy feeling, and appetite loss. So the right answer is D. MMDA
