21. State 3 lifestyle choices that can help prevent or control type 2 diabetes. (max. 3 marks) There are 3 distinct lifestyles choices that can help prevent or control types 2 diabetes, they include:
Consuming low glycemic foods that are rich in nutrients and fibre as part of a healthy diet. participating in physical activity regularly with moderate exercise maintain a healthy body weight
All these choice can help an individual prevent type two diabetes. By working on choices one and two you are simultaneously achieving choice three.
22. What are 2 characteristics of saturated fatty acids? (max. 2 marks)
Saturated fatty acids are distinct from unsaturated fatty acids due to the fact that there are no double bonds present in the chemical makeup of the molecule. Furthermore, substances that are composed of …show more content…
What are 4 risk factors for cardiovascular disease? (max. 4 marks) There are four factors that can increase an individual’s risk for cardiovascular disease:
Excessive weight
Lack of physical activity
Smoking
Inflammation
26. How are proteins distinct from carbohydrates and lipids? (max. 1 mark)
Proteins are unique from carbohydrates and lipids due to the fact they are the only macronutrient that can be manufactured by the body. Proteins also contain the element nitrogen while carbohydrates and lipids do not. Finally, the fundamental building blocks of proteins are made of amino acids.
27. Explain how genes regulate amino acid sequence. (max. 3 marks)
A portion of a gene is needed in order to make a protein. mRNA is made by being transcribed by the DNA template. mRNA is then translated into a specific order of amino acids based on complementary base pairs. The amino acids grow in a chain and produces a protein.
28. How do proteins strengthen the immune system? (max. 1 mark)
Proteins can act as antibodies that attack and destroy antigens. In doing so, proteins strengthen the immune system.
29. Explain the concept of “nitrogen balance”. (max. 2
