    The metabolic rate ______ as we exercise

    • A.

      Decreases

    • B.

      Increases

    • C.

      Stays the same

    Correct Answer
    B. Increases
    Explanation
    During exercise, the body requires more energy to fuel the muscles and maintain physical activity. To meet this increased demand, the metabolic rate increases. This means that the body processes and converts nutrients into energy at a faster rate, allowing for the necessary fuel to be supplied to the working muscles. As a result, the body burns more calories and experiences an increase in metabolic rate during exercise.

    Rate this question:

  • 18. 

    After exercise the metabolic rate ...

    • A.

      Falls quickly

    • B.

      Stays high for a while

    • C.

      Falls before rising again

    Correct Answer
    B. Stays high for a while
    Explanation
    After exercise, the metabolic rate stays high for a while. This is because during exercise, the body burns calories and increases the demand for energy. After exercise, the body continues to burn calories at an elevated rate to replenish energy stores, repair tissues, and restore normal body functions. This elevated metabolic rate can last for several hours, depending on the intensity and duration of the exercise. Therefore, staying active and exercising regularly can help maintain a higher metabolic rate, which can aid in weight management and overall health.

      HDLs

    • B.

      LDLs

    • C.

      Fats

    Correct Answer
    B. LDLs
    Explanation
    LDLs, also known as low-density lipoproteins, are considered bad cholesterol because they can lead to the accumulation of fat on the walls of arteries. This buildup of fat can eventually cause heart disease. HDLs, on the other hand, are considered good cholesterol as they help remove LDLs from the bloodstream, reducing the risk of heart disease. Fats, in general, can contribute to the formation of LDLs and should be consumed in moderation to maintain a healthy cholesterol level.

    Rate this question:

  • 35. 

    ______ are good cholesterol as they stop fat building up in arteries

    • A.

      HDLs

    • B.

      LDLs

    • C.

      Fats

    Correct Answer
    A. HDLs
    Explanation
    HDLs, also known as high-density lipoproteins, are considered good cholesterol because they help remove excess cholesterol from the bloodstream and prevent the buildup of fat in arteries. They transport cholesterol from the arteries to the liver, where it can be broken down and eliminated from the body. This process reduces the risk of heart disease and other cardiovascular problems associated with the accumulation of cholesterol in the arteries.

    Rate this question:

  • 36. 

    A _____ proportion of HDLs to LDLs is good for the heart

    • A.

      Similar

    • B.

      Low

    • C.

      High

    Correct Answer
    C. High
    Explanation
    A high proportion of HDLs to LDLs is good for the heart because HDLs (high-density lipoproteins) are considered "good" cholesterol, as they help remove LDLs (low-density lipoproteins) from the bloodstream. LDLs, on the other hand, are considered "bad" cholesterol, as they can build up in the arteries and lead to heart disease. Therefore, a higher proportion of HDLs to LDLs indicates a healthier balance of cholesterol and a lower risk of heart problems.

    Rate this question:

  • 37. 

    1)         unsatured and 2)         unsaturated fats help to reduce cholesterol in the blood and increase the proportion of HDLs to LDLs   1) / 2) =

    Correct Answer
    poly
    mono
    Explanation
    Polyunsaturated and monounsaturated fats help to reduce cholesterol in the blood and increase the proportion of HDLs (good cholesterol) to LDLs (bad cholesterol). Polyunsaturated fats contain multiple double bonds in their chemical structure, while monounsaturated fats have a single double bond. Both types of fats are considered healthier options compared to saturated fats, which can increase cholesterol levels and the risk of heart disease. Consuming a diet rich in polyunsaturated and monounsaturated fats can have a positive impact on cardiovascular health.

    Rate this question:
