Question 1

Which of the following best describes an oligosaccharide?

Accepted Answer

A small polymer made up of a few monosaccharide units

Question 2

Which general formula represents most monosaccharides?

Accepted Answer

$C_nH_{2n}O_n$

Question 3

A monosaccharide with a carbonyl group at the end of its carbon chain is classified as a(n):

Accepted Answer

Aldose

Question 4

Which of the following is a correct example of a glycosidic linkage?

Accepted Answer

A covalent bond formed between two monosaccharides during dehydration synthesis

Question 5

Which of the following best explains why cellulose is important in the human diet?

Accepted Answer

It acts as dietary fiber because humans cannot hydrolyze its $\beta$-1,4-glycosidic linkages

Question 6

Which of the following is NOT a function of carbohydrates in cells?

Accepted Answer

Catalyzing chemical reactions

Question 7

A disaccharide is formed when:

Accepted Answer

Two monosaccharides are joined by a glycosidic linkage

Question 8

Which of the following best describes the role of glycoproteins in cell membranes?

Accepted Answer

They display information for cell-cell recognition and signaling

Question 9

Which equation correctly represents the process of photosynthesis?

Accepted Answer

$6CO_2 + 6H_2O + 	ext{sunlight} ightarrow C_6H_{12}O_6 + 6O_2$

Question 10

Which of the following statements about chitin is correct?

Accepted Answer

It contains nitrogen groups, giving it extra strength compared to cellulose

Question 11

Which of the following best explains why glycogen is an effective energy storage molecule in animals?

Accepted Answer

It has many branches, allowing rapid release of glucose when needed

Question 12

Which of the following is a correct description of the relationship between photosynthesis and cellular respiration?

Accepted Answer

Photosynthesis stores energy in glucose, while respiration releases that energy for cellular use

Question 13

Which of the following best describes the function of peptidoglycan?

Accepted Answer

It provides structural support in bacterial cell walls

Question 14

Which of the following is a correct statement about isomers of monosaccharides?

Accepted Answer

They have the same molecular formula but different arrangements of atoms

Question 15

A patient is diagnosed with a deficiency in the enzyme that breaks $\alpha$-1,4-glycosidic linkages. Which dietary component will they have trouble digesting?

Accepted Answer

Starch

Question 16

Which of the following best explains why carbohydrates are used as an identification badge for cells?

Accepted Answer

Carbohydrates on glycoproteins and glycolipids display information for cell-cell recognition

Question 17

Which of the following best describes the energy stored in glucose?

Accepted Answer

It is stored in the carbon-carbon and carbon-hydrogen bonds

Question 18

Which of the following is a real-life example of carbohydrate function in cell identity?

Accepted Answer

ABO blood group antigens on red blood cells

Question 19

Which of the following statements about dietary fiber is correct?

Accepted Answer

It consists mainly of carbohydrates that cannot be hydrolyzed by human enzymes

Question 20

If a plant cell is unable to synthesize cellulose, which of the following would most likely be affected?

Accepted Answer

The structural integrity of the cell wall
