  • 2. 

    Glucose and fructose are examples of what building block?

    • A. 

      Polysaccahrides

    • B. 

      Disaccharides

    • C. 

      Monosaccharides

    • D. 

      Amino Acids

    Correct Answer
    C. Monosaccharides
    Explanation
    Glucose and fructose are both simple sugars, which are classified as monosaccharides. Monosaccharides are the basic building blocks of carbohydrates, consisting of a single sugar molecule. They cannot be further broken down into simpler sugars. Polysaccharides are complex carbohydrates made up of multiple monosaccharide units, such as starch and cellulose. Disaccharides, on the other hand, are composed of two monosaccharide units joined together, such as sucrose and lactose. Amino acids are the building blocks of proteins and are not related to glucose and fructose.

    Rate this question:

  • 3. 

    What is the function of a carbohydrate?

    • A. 

      Used to help water dissolve

    • B. 

      Used to clean liver

    • C. 

      Used by cells to store and release energy

    • D. 

      Used for chemical reactions

    Correct Answer
    C. Used by cells to store and release energy
    Explanation
    Carbohydrates are molecules that are used by cells to store and release energy. They are broken down into glucose, which is then used as a primary source of energy by the cells. Carbohydrates provide a quick and easily accessible source of energy for the body, making them essential for various cellular processes and bodily functions.

    Rate this question:

  • 4. 

    How are carbohydrates formed?

    • A. 

      By linking shorter units together to form long sugar chains

    • B. 

      Fats stored and built up in the body

    • C. 

      Fats combined together

    • D. 

      They are not formed, found directly in food

    Correct Answer
    A. By linking shorter units together to form long sugar chains
    Explanation
    Carbohydrates are formed by linking shorter units together to form long sugar chains. These shorter units, known as monosaccharides, are joined together through chemical bonds to create larger molecules like disaccharides and polysaccharides. This process of linking units allows for the formation of complex carbohydrates found in foods such as grains, fruits, and vegetables. These carbohydrates serve as a crucial source of energy for the body and play a vital role in various physiological processes.

  • 5. 

    What is an not an example of a carbohydrate?

    • A. 

      Bread

    • B. 

      Celery

    • C. 

      Pasta

    • D. 

      Rice

    Correct Answer
    B. Celery
    Explanation
    Celery is not an example of a carbohydrate because it is a low-calorie vegetable that is primarily composed of water and fiber. Carbohydrates are typically found in foods like bread, pasta, and rice, which are rich in starches and sugars. However, celery is a non-starchy vegetable that contains very few carbohydrates and is often considered a good choice for low-carb or ketogenic diets.

    Rate this question:

  • 6. 

    How many calories are are in a gram of carbohydrates?

    • A. 

      25

    • B. 

      16

    • C. 

      4

    • D. 

      9

    Correct Answer
    C. 4
    Explanation
    Carbohydrates are one of the three macronutrients and provide energy to the body. They contain 4 calories per gram, making the correct answer 4.

    Rate this question:

  • 7. 

    What percent of calories come from carbohydrates?

    • A. 

      30-44%

    • B. 

      85-99%

    • C. 

      75-80%

    • D. 

      45-65%

    Correct Answer
    D. 45-65%
    Explanation
    The correct answer is 45-65%. This range represents the recommended percentage of calories that should come from carbohydrates in a balanced diet. Carbohydrates are an essential source of energy for the body, and this range ensures that individuals consume enough carbohydrates to meet their energy needs while also maintaining a balanced intake of other macronutrients.

    Rate this question:

  • 8. 

    How many grams of carbohydrates do you need a day?

    • A. 

      130

    • B. 

      56

    • C. 

      10

    • D. 

      95

    Correct Answer
    A. 130
    Explanation
    The recommended daily intake of carbohydrates for an average adult is around 130 grams. Carbohydrates are the body's main source of energy, and they are essential for proper brain and muscle function. Consuming an adequate amount of carbohydrates helps maintain blood sugar levels, supports digestion, and provides fuel for physical activity. It is important to note that individual carbohydrate needs may vary depending on factors such as age, sex, activity level, and overall health.

    Rate this question:

  • 9. 

    Carbohydrates require _____ water to digest then proteins and fats.

    • A. 

      More

    • B. 

      Equal amount

    • C. 

      Less

    • D. 

      Way more

    Correct Answer
    C. Less
    Explanation
    Carbohydrates require less water to digest compared to proteins and fats. This is because carbohydrates are broken down into simpler sugars during digestion, and these sugars are easily absorbed by the body. Proteins and fats, on the other hand, require more water for digestion as they need to be broken down into amino acids and fatty acids respectively, which are then absorbed by the body. Therefore, carbohydrates have a lower water requirement for digestion.

    Rate this question:

  • 10. 

    What are the 2 types of carboydrates?

    • A. 

      Safe and unhealthy

    • B. 

      Bad and good

    • C. 

      Great and excellent

    • D. 

      Simple and complex

    Correct Answer
    D. Simple and complex
    Explanation
    The correct answer is simple and complex. Carbohydrates are classified into two types based on their chemical structure: simple and complex. Simple carbohydrates, also known as sugars, are composed of one or two sugar molecules and are quickly digested by the body, providing a quick source of energy. Complex carbohydrates, on the other hand, are made up of multiple sugar molecules and take longer to digest, providing a sustained release of energy.
