Question 1

Which of the following is not a carbohydrate term?&#10;A)Glycogen&#10;B)Monosaccharide&#10;C)Glycerol&#10;D)Sucrose,maltose,and lactose

Accepted Answer

Glycerol is a type of alcohol that is not classified as a carbohydrate. Glycogen, monosaccharide, and the disaccharides sucrose, maltose, and lactose are all carbohydrate terms.

Question 2

Which of the following is least related to lactic acid?&#10;A)Glycolysis&#10;B)Krebs cycle&#10;C)Anaerobic&#10;D)Cytoplasm

Accepted Answer

The Krebs cycle is least related to lactic acid because lactic acid is primarily produced during anaerobic glycolysis in the cytoplasm, not in the Krebs cycle, which occurs in the mitochondria and is part of aerobic respiration.

Question 3

Which of the following processes forms the most ATP?&#10;A)Glycolysis&#10;B)Conversion of glucose to glycogen&#10;C)Aerobic catabolism of glucose&#10;D)Catabolism of glucose to lactic acid

Accepted Answer

Aerobic catabolism of glucose (i.e., cellular respiration) forms the most ATP. It produces 36-38 ATP molecules per glucose molecule, while glycolysis produces only 2 ATP molecules and the catabolism of glucose to lactic acid produces 2 ATP molecules. The conversion of glucose to glycogen does not produce ATP, as it is a process of storing glucose for later use.

Question 4

Which of the following describes the breakdown of glucose to lactic acid?&#10;A)Aerobic&#10;B)Krebs cycle&#10;C)Glycolysis&#10;D)Gluconeogenesis

Accepted Answer

Glycolysis is the breakdown of glucose to pyruvate or lactic acid, and occurs in the cytoplasm of cells. This pathway does not require oxygen and is therefore anaerobic. The breakdown of pyruvate to carbon dioxide and water occurs during the Krebs cycle, which is an aerobic process that occurs in the mitochondria. Gluconeogenesis is the process by which glucose is synthesized from non-carbohydrate sources such as amino acids or fatty acids, and is not related to the breakdown of glucose to lactic acid.

Question 5

The best method for decreasing blood cholesterol level is to&#10;A)decrease dietary intake of cholesterol.&#10;B)decrease dietary intake of saturated fat.&#10;C)increase protein intake.&#10;D)increase carbohydrate intake.

Accepted Answer

Decreasing dietary intake of saturated fat is the best method for decreasing blood cholesterol levels as saturated fat intake directly affects cholesterol levels. Cholesterol is primarily found in animal-based foods, but the liver can also produce cholesterol. Consuming foods high in saturated fat, such as fatty meats, butter, and cheese, increases the liver's production of cholesterol, which results in higher blood cholesterol levels. Therefore, decreasing saturated fat intake can lower blood cholesterol levels. Increasing protein intake or carbohydrate intake is not an effective method for decreasing blood cholesterol levels.

Question 6

In the absence of oxygen,glucose is catabolized to&#10;A)lactic acid.&#10;B)carbon dioxide and water.&#10;C)urea.&#10;D)fatty acid.

Accepted Answer

In the absence of oxygen, glucose undergoes anaerobic respiration where it is only partially catabolized, resulting in the production of lactic acid. This process is also known as fermentation. Therefore, option A is the correct choice. Option B is incorrect because it applies to aerobic respiration. Options C and D are also incorrect because glucose is not catabolized to urea or fatty acids in the absence of oxygen.

Question 7

Starches,amylases,and disaccharidases are related to&#10;A)carbohydrates.&#10;B)steroids.&#10;C)enzymes.&#10;D)peptides.

Accepted Answer

Starches are a type of carbohydrate, amylases are enzymes that break down carbohydrates, and disaccharidases are enzymes that break down disaccharides, which are also carbohydrates.

Question 8

Sucrose,lactose,and maltose are classified as&#10;A)enzymes.&#10;B)disaccharides.&#10;C)peptides.&#10;D)nucleotides.

Accepted Answer

Sucrose, lactose, and maltose are all examples of disaccharides, which are carbohydrates made up of two monosaccharides (simple sugars). Enzymes are proteins that catalyze biochemical reactions, peptides are chains of amino acids, and nucleotides are the building blocks of nucleic acids.

Question 9

Which of the following is most related to glycolysis?&#10;A)Krebs cycle&#10;B)Mitochondria&#10;C)Lactic acid&#10;D)Aerobic

Accepted Answer

Glycolysis is a process that occurs in the cytoplasm of the cell and involves the breakdown of glucose into pyruvate. Lactic acid is a byproduct of glycolysis when there is insufficient oxygen available, leading to anaerobic respiration. Krebs cycle and mitochondria are both part of aerobic respiration, which occurs after glycolysis if oxygen is present, but are not directly related to glycolysis itself.

Question 10

Which of the following is most descriptive of glucose?&#10;A)Disaccharide&#10;B)Peptide&#10;C)Glycerol&#10;D)Carbohydrate

Accepted Answer

Glucose is a type of carbohydrate, specifically a monosaccharide. It is a simple sugar that is used as a source of energy in the body. It is not a disaccharide, peptide, or glycerol.
