Explanation:

C. They make it more fluid

Lipids are composed of fatty acids which form the hydrophilic head and glycerol which forms the hydrophilic tail; their arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Cholesterol, which is comparatively rigid, anchors other molecules attached to the membrane, maintain membrane stability or structural integrity  and aid in separating some lipids, helping with membrane fluidity at low environmental temperatures.

FrozenT [24]

An enzymatic weight-gain supplement claims to help users digest all carbohydrates in fruits and vegetables. Cellulase enzyme is present.

<h3>What is cellulase ?</h3>

Cellulase (systematic name 4—D-glucan 4-glucanohydrolase) is any of a number of enzymes that catalyse cellulolysis, the breakdown of cellulose and some related polysaccharides, and is primarily produced by fungi, bacteria, and protozoans.

Endohydrolysis of (14)-D-glucosidic linkages in lichenin, cereal -D-glucan, and cellulose

The term is also applied to any naturally occurring combination or complex of numerous such enzymes that break down cellulosic material sequentially or cooperatively.

Cellulases convert the cellulose molecule into shorter polysaccharides and oligosaccharides, as well as monosaccharides (or "simple sugars") like -glucose. Because it makes a key plant component usable for food and use in chemical reactions, cellulose breakdown has significant economic significance. The 1,4-D-glycosidic bonds in cellulose, hemicellulose, lichenin, and cereal -D-glucans are hydrolyzed in this particular process. Compared to the breakdown of other polysaccharides like starch, the breakdown of cellulose is particularly challenging because the molecules of cellulose bind tightly to one another.

Why are antibiotics ineffective against viruses?
vagabundo [1.1K]

Answer:

antibiotics are useless against viral infections this is because viruses are so simple that they use their host cells to perform their activities for them. so antiviral drugs work differently to antibiotics by interfering with the viral enzymes instead
