Explanation:

Unlike carbohydprices and proteins, lipids are greatly nonpolar molecules. As an outcome, they are unable to be dissolved in aqueous services, such as blood. This provides them need a lipoprotein in order to be transported through the bloodstream. Without these proteins, lipids would certainly be insoluble in the blood and cause clots.

You are watching: Gram for gram, which provides the most energy?


Explanation:

Amphipathic molecules have actually both polar and nonpolar sections. For phospholipids, the phosphate area carries an unfavorable charge, making it polar, while the lipid tail is a nonpolar hydrocarbon. Being amphipathic is a crucial characteristic that permits phospholipids to create the plasma membrane. The polar ends are able to confront the aqueous environment while the nonpolar ends are challenged towards each various other. This creates an efficient nonpolar barrier around the cell, while still continuing to be secure by having actually polar regions facing the aqueous settings.

Example Concern #1 : Understanding Lipids And Carbohydrates


Which carbohydrate cannot be digested by humans?


Possible Answers:

Amylose


Glycogen


Starch


Cellulose


Correct answer:

Cellulose


Explanation:

Cellulose is a polysaccharide in which the monomers are connected by a beta affiliation. This affiliation requires a specialized enzyme that is not found in humans. As an outcome, human beings cannot break down cellushed.

Glycogen is used to store glucose in the body, and also have the right to be damaged down to release energy. Starch is offered to keep glucose in plants, yet can additionally be damaged down by humans. Amyshed is a component of starch.

Example Inquiry #1 : High School Biology


Which of the adhering to classes of molecules produces the most power per gram?


Possible Answers:

Fats


Carbohydrates


Nucleic acids


Fibers


Proteins


Correct answer:

Fats


Explanation:

Tright here are 4 classes of biological molecules: fats, carbohydprices, proteins, and also nucleic acids. Of these, fats produce the a lot of power per gram at a whopping nine calories per gram. Carbohydrates and also proteins develop much less than half of this, at just 4 calories per gram.

Example Inquiry #2 : High School Biology


Which of the complying with is not a type of fat in the body?


Possible Answers:

Mono-unsaturated fats


Saturated fats


Unsaturated fats


Di-saturated fats


Trans fats


Correct answer:

Di-saturated fats


Explanation:

Lipids, or fats, are created from hydrocarbon chains. The carbon atoms connect together and also bond to hydrogen to fill their orbitals. When all the bonds in the molecule are single bonds, the lipid is saturated. There is no such point as a "di-saturated fat."

When there is a solitary double bond in the chain, the lipid is mono-unsaturated. When tright here are multiple double bonds in the chain, the lipid is unsaturated. Trans fats have a twin bond with the nearby hydrogen atoms on oppowebsite sides of the carbon chain, maintaining a linear structure.

Many fats in the body are triglycerides. Their main function is long-term energy storage.

Example Question #1 : Macromolecules


Which of the adhering to is a carbohydrate?


Possible Answers:

Ribose


Cholesterol


Triglyceride


Insulin


Helicase


Correct answer:

Ribose


Explanation:

Carbohydprices are known as sugars or saccharides. Virtually all carbohydprices end in the sufresolve "-ose," making them straightforward to identify. Ribose is a five-carbon sugar found in RNA. Some other prevalent carbohydrates encompass deoxyribose, glucose, cellushed, and also lactose. Succlimbed is the technical name of table sugar, which is likewise a carbohydprice.

The other classes of molecules are fats, proteins, and nucleic acids. Fats, or lipids, deserve to be further broken down right into other categories, such as sterols and also glycerolipids. Sterol lipids mainly have actually the suffix "-ol" and also encompass cholesterol and also estradiol (estrogen). Glycerolipids incorporate triglycerides. Proteins are developed from amino acids. Enzymes are a course of protein and also mostly have actually the sufresolve "-ase," such as helicase. Other proteins frequently have the sufsettle "-in" or "-en," such as insulin.

Example Inquiry #1 : Macromolecules


Which of the following are true regarding lipids?


Possible Answers:

Lipids are hydrophilic


Lipids have the right to only be triglycerides


Lipids execute not store energy


Lipids are soluble in water


Lipids are soluble in nonpolar solvents


Correct answer:

Lipids are soluble in nonpolar solvents


Explanation:

Lipids are hydrophobic, which indicates that they are insoluble in water, a polar solvent. Lipids deserve to keep plentiful energy. Lipids contain huge nonpolar regions, which suggests that they are soluble in nonpolar solvents. Triglycerides are only one kind of lipids. Other forms encompass, but are not restricted to: monoglycerides, diglycerides, phospholipids, and also fatty acids.

Example Question #1 : Understanding Lipids And Carbohydrates


What is the distinction in between saturated and unsaturated fatty acids?

I. Saturated fatty acids execute not contain double bonds, unsaturated fatty acids contain at leastern one double bond

II. Saturated fatty acids contain at leastern one double bond, unsaturated fatty acids execute not contain double bonds

III. Saturated fatty acids contain the maximum amount of H atoms on their carbon skeletons

IV. Unsaturated fatty acids contain the maximum amount of H atoms on their carbon skeletons


Possible Answers:

III only


I only


II only


II and IV


I and also III


Correct answer:

I and III


Explanation:

Saturated fatty acids perform not have double bonds between carbon atoms. Thus, the maximum amount of hydrogen atoms are bonded to the carbon skeleton chain. Saturated fatty acids are solid at room temperature, choose butter. Unsaturated fatty acids have at lease one double bond. These double bonds develop kinks in the carbon skeleton, preventing hydrogen atoms from packing onto the skeleton. Unsaturated fatty acids are therefore even more liquid and also are liquid at room temperature, favor oil and organic peanut butter.

Example Question #9 : Macromolecules


What is true of both lipids and fats?

I. Both are macromolecules

II. Both are hydrophobic

III. Fats are composed of glycerol and fatty acids

IV. Lipids are written of glycerol and fatty acids

V. Fats are organized together by means of ester linkage


Possible Answers:

I, II, IV, and also V


I, II, and V


I and II


II, III, and V


I, III, and also IV


Correct answer:

II, III, and also V


Explanation:

Because lipids do not include true polymers, they are not massive enough to be taken into consideration macromolecules. However, choose fats, lipids are hydrophobic. Fats are considered macromolecules and are created of glycerol and fatty acid molecules. The glycerol and also fatty acid molecules are joined by means of an ester affiliation, which is created by a dehydration reactivity.

What sugar molecule does ATP contain?


Possible Answers:

Adenine


Adenosine


Deoxyribose


Triphosphate


Ribose


Correct answer:

Ribose


Explanation:

ATP means adenosine triphosphate. Ribose is the five-carbon sugar, which is bonded to a phosphate group and also adenine group in a molecule of ATP.
