Answer:

C. glycoproteins

Explanation:

Glycoproteins are proteins containing glycans (oligosaccharide carbohydrates) attached to amino acid side chains. These oligosaccharides are attached to the amino acid chain by a posttranslational modification referred to as glycosylation, a modification generally found in extracellular regions. Glycosylation refers to the chemical reaction in which a glycosyl donor (i.e., the carbohydrate) is attached to a functional group in the protein. The glycosylation sites play distinct functional roles for both cell interactions and cell recognition. Moreover, glycosylation sites are also essential for substrate recognition by an enzyme. For example, secreted cytokines are glycosylated, which is required for their binding to receptors.

Increasing the substrate concentration in an enzymatic reaction could overcome which of the following?
bixtya [17]

Answer:

(C) Competitive inhibition

Explanation:

When a substrate competes with and inhibitor, what they are actually doing is competing by the active site of the enzyme. In terms of probabilities, when there is much more of one molecule of X than its competitor Y, it is more likely for any of the molecules of X to reach the active site of the enzyme than for any of the molecules of Y.

Then is one would like to reduce the effects of an inhibitor reversible bonded to an enzyme, one possibility is to increase the concentration of a substrate (which in turn means that there will be a higher relative number of its molecules in the media), increasing the probability to meet the active site of the enzyme and as a result displacing the inhibitor (assuming it not increased as well).

Scientists have discovered that the inner core of Earth is a solid while the outer core is a liquid. What is the cause of this o
Arte-miy333 [17]

Answer:

Scientists figured out that the outer core must be liquid because S waves do not pass through it, but P waves do. The behavior of P and S waves also indicates that the inner core is solid. The speed of seismic waves also depends on the density of the material through which they are traveling.

Which best explains the surface tension of water?
ExtremeBDS [4]

B.) Cohesion

Explanation:

The best term that fits the description of the term surface tension of water is cohesion.

Cohesion is the intermolecular forces that holds together the particles of liquids and solids.

  • Surface tension is a phenomenon in liquids that causes them to come together more and shrink on the surface.
  • Surface tension is made possible by cohesive forces between water- water molecules.
  • Adhesion is between different molecules like water and glass.
  • In capillary action, a liquid is able to rise up in a column
  • Sublimation is a phase change from solid to gas.
