Fats and oils provide:
- A.
Metabolism improvement
- B.
Health benefits
- C.
Energy Storage
- D.
None of the above
Correct Answer
C. Energy StorageExplanation
Fats and oils provide energy storage in the body. When consumed, they are broken down into fatty acids, which can be stored in adipose tissue for later use. This stored energy can be utilized by the body when needed, such as during periods of fasting or intense physical activity. Fats and oils are a concentrated source of calories and provide a long-lasting source of energy compared to carbohydrates or proteins. Therefore, the correct answer is energy storage.Rate this question:

Which of the following is not a feature of saturated fats?
- A.
Maximum number of hydrogen atoms
- B.
Straight Chain
- C.
Oxidation at double bonds
- D.
Forms solids readily
Correct Answer
C. Oxidation at double bondsExplanation
Saturated fats do not have any double bonds in their chemical structure. Therefore, they cannot undergo oxidation at double bonds. This is because oxidation reactions typically occur at double bonds, where unsaturated fats are more susceptible to oxidation. Saturated fats have the maximum number of hydrogen atoms and a straight chain structure, and they form solids readily due to their closely packed molecules.Rate this question:

Which of the following is not a feature of unsaturated fats?
- A.
Forms solids readily
- B.
2 or more carbon atoms with double bonds
- C.
Bent chains
- D.
Oxidation at double bonds
Correct Answer
A. Forms solids readilyExplanation
Unsaturated fats are known for their ability to remain in a liquid state at room temperature, unlike saturated fats which solidify. Therefore, the statement "Forms solids readily" is not a feature of unsaturated fats. Unsaturated fats have one or more double bonds between carbon atoms, resulting in bent chains. These double bonds are also susceptible to oxidation, which can lead to rancidity.Rate this question:

_________ makes up plant cell walls.
- A.
Sugars
- B.
Cellulose
- C.
Fats
- D.
Oils
Correct Answer
B. CelluloseExplanation
Cellulose is the correct answer because it is a complex carbohydrate that makes up the structural component of plant cell walls. It provides strength and rigidity to the cell walls, allowing plants to maintain their shape and withstand environmental pressures. Sugars, fats, and oils do not have the same structural properties as cellulose and therefore do not make up plant cell walls.Rate this question:

______ is a highly elastic network of interacting molecules.
Correct Answer
glutenExplanation
Gluten is a highly elastic network of interacting molecules. Gluten is a protein found in wheat and other grains, such as barley and rye. When gluten is mixed with water, it forms a sticky and elastic network that gives dough its structure and allows it to rise. This elasticity is what gives bread its chewy texture and allows it to hold its shape during baking. Gluten also provides the ability to trap air bubbles, resulting in a light and fluffy texture in baked goods.Rate this question:
- 10.
In proteins the ___________ of the molecules yield its functionality.
Correct Answer
bonds
bondExplanation
In proteins, the bonds between the molecules determine their functionality. These bonds can be either weak or strong and can include covalent bonds, hydrogen bonds, and disulfide bonds. The specific arrangement and strength of these bonds contribute to the protein's overall structure and shape, which in turn determines its function. Therefore, the bonds present in proteins are crucial for their proper functioning.Rate this question:

Collagen is found where?
- A.
Bacteria
- B.
Man-made
- C.
Plant walls
- D.
Mammal protein
Correct Answer
D. Mammal proteinExplanation
Collagen is a protein that is primarily found in mammals. It is a major component of connective tissues, such as skin, tendons, ligaments, and bones. Collagen provides structural support and strength to these tissues, helping to maintain their integrity and function. While collagen can also be found in other animals and some plant tissues, it is most commonly associated with mammal proteins.Rate this question:

______ is also known as "meat glue."
Correct Answer
transglutenaseExplanation
Transglutenase is also known as "meat glue" because it is an enzyme that is commonly used in the food industry to bind proteins together. It has the ability to bond different pieces of meat together, creating a larger, more cohesive piece. This process is often used to create products like chicken nuggets or imitation crab meat, where smaller pieces of meat are combined to form a larger, more desirable shape. The term "meat glue" is used colloquially to describe this process because it essentially acts as a glue, holding the pieces of meat together.Rate this question:

___________ is how an object deforms and flows under applied stress.
Correct Answer
RheologyExplanation
Rheology is the study of how materials deform and flow under applied stress. It involves the study of the flow properties of liquids, the deformation and flow of solids, and the viscoelastic behavior of materials. Rheology helps in understanding how materials behave under different conditions, such as temperature, pressure, and shear rate. By studying rheology, scientists and engineers can better understand and predict the behavior of materials in various applications, such as in manufacturing processes, product development, and quality control.Rate this question:

Starch is soluble in cold water.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Starch is not soluble in cold water. Starch is a complex carbohydrate made up of glucose molecules, and it requires heat to break down its structure and become soluble. Cold water cannot provide enough energy to disrupt the hydrogen bonds that hold the glucose molecules together in starch, making it insoluble.Rate this question:

Which of the following is not a use for gums?
- A.
Gelling agents
- B.
Bread
- C.
Candies
- D.
Ice creams
Correct Answer
B. BreadExplanation
Bread is not a use for gums because gums are primarily used as gelling agents, stabilizers, or thickeners in various food products. They help to improve texture, increase shelf life, and enhance the overall quality of food items. While gums may be used in candies and ice creams to achieve these purposes, they are not typically used in bread-making processes. Bread relies on other ingredients like yeast, flour, and water for its texture and structure. Therefore, bread is not a use for gums.Rate this question:

What makes a product low-carb?
- A.
Dispersible in water
- B.
Used a gelling agent
- C.
Additional hydrogen atoms
- D.
None of the above
Correct Answer
C. Additional hydrogen atomsExplanation
Adding additional hydrogen atoms to a product does not make it low-carb. The concept of low-carb refers to the amount of carbohydrates present in a product, not the addition of hydrogen atoms. Therefore, the option "Additional hydrogen atoms" is not a valid explanation for what makes a product low-carb.Rate this question:

_________ improves nutritional component.
Correct Answer
fortificationExplanation
Fortification is the process of adding essential nutrients to food products, thereby improving their nutritional component. This can include adding vitamins, minerals, or other beneficial substances to address deficiencies in the diet. Fortification is commonly used to enhance the nutritional value of staple foods, such as flour, rice, or milk, and is an effective strategy to combat malnutrition and improve public health. By fortifying food, individuals can easily obtain the necessary nutrients, leading to improved overall nutrition and better health outcomes.Rate this question:
