QUESTION 12
When blood glucose levels are too low, a person might feel fatigued, irritable, and/or confused. Why is this?
Cells primarily use glucose as an energy source but most also can use fats or protein. |
||
Glucose is used by all cells for energy, but exclusively by brain and nerve cells. |
||
Glycogen is stored within liver and muscle tissue and can be released when needed. |
||
Any of the monosaccharides can be used to meet the energy needs of the cells. |

QUESTION 15
What is hydrogenation?
When a chemical molecule is changed by adding water molecules. |
||
The process of taking a chemical and changing it by emulsifying the fat. |
||
Taking an unhealthy saturated fatty acid and modifying it so that it provides more health benefits. |
||
The process of adding hydrogen to unsaturated fatty acids resulting in a more saturated fatty acid |
Ans 5) Eating raw foods high in starch provides little energy as the body has to work harder to digest them, instead eating cooed food with high in starch will provide lots of energy.
6) Polysaccharides are slow releasing sugars because they slowly release energy over long periods of time.
7) Whole grains are healthy because they have fibres, vitamins and minerals compared to those low quality carb food which don't have such benefits.
8) Out brain solely depends on glucose as it's main source of energy.
9) Those all are examples dietary fibres.
10) When glucose levels are high insulin is released and when glucose levels are low glucagon is released which stimulates liver to break down glycogen and release glucose.
11) Sucrose is called as table sugar which is made up of glucose and fructose.
12) Glucose is used as main source of energy for cells but exclusively for brain and neurons and lack of glucose in body give rise to fatigue, confusion and irritation.
13) High fructose corn syrup provides artificial sweetness to the product as fructose is sweet.
14) For this the answer will be option A as it has all the risk factors that can be controlled. Other options do not contain all the risk factors.
15) Hydrogenation is the process of adding hydrogen to unsaturated fatty acid chains making them saturated fatty acid.
Hope this helps, Good luck!!!
