The female steroid hormone – estrogen is a derived lipid.
True
Cholesterol is the most common steroid
True
Triglycerides within the body are ingested as food or synthesized by hepatocytes only.
False
It is the intestine where ingested triglycerides are broken down into smaller chain fatty acid and subsequently into monoglyceride molecules by pancreatic lipases, enzymes that break down fats after they are emulsifies by bile salts
False
Oil and water don’t mix because water has polar bonds whiles oils have non polar bonds.
True
Bile salts help emulsify fat droplets.
True
In the process of lipogenesis, fats are broken down from Acetyl CoA and takes place in the cytoplasm of adipocytes and hepatocytes.
False
Vitamin E is the most powerful antioxidant than vitamin C.
True
The main role of vitamin K is in blood clotting
True
Vitamin C is water soluble and easily destroyed by heat, alkali and storage.
True

1st statement is FALSE and 2nd statement is TRUE
● Cholesterol is precursor of steroid.

Both statements are TRUE
● Lipids are more soluble in water.
● Lipids are either strongly hydrophobic or amphipathic.
1st statement is FALSE and 2nd statement is TRUE
● Tran’s fat is created in an industrial process that adds hydrogen.
● Transfat can also be called “partially hydrogenated”.
Both statements are TRUE
What will happen if hydrogenation process occurs in unsaturated fatty acid?
Unsaturated fatty acids will become liquid.
Unsaturated fatty acids will lose its double bond to form single bond.
Unsaturated fatty acids will form another double bond to cater the other
hydrogen.
Unsaturated fatty acids will disintegrate and dissolved.
Unsaturated fatty acids will lose its double bond to form single bond.
You woke up at 6 am prepared yourself to school. Your mother cooked eggs as your breakfast. What will happen to the eggs if you swallow it?
It will be broken into pieces through mechanical digestion in the mouth and chemical digestion in the stomach and being absorbed in the small intestine to be used in the whole body.
It will be broken down into pieces by using teeth and the eggs will be
dissolved in the stomach where it contains high acidity in the body.
It will be broken down into pieces and swallowed through peristalsis of the
esophagus where it will go to the stomach to be digested thoroughly in order
for the body to use it immediately.
None of these
It will be broken into pieces through mechanical digestion in the mouth and chemical digestion in the stomach and being absorbed in the small intestine to be used in the whole body.
A 55-year old patient is complaining of suffering from abdominal cramps or fullness in his stomach after 30mins of eating and he has an unintended weight loss for these past few months. His medical history shows also that he has hypertension. What could be the possible cause?
Too much release of lipases in the small intestine.
Lack of digested lipid going to the intestinal cells.
There is not enough blood distributed to the intestine because of artery
blockage.
There is an inflammation between the intestinal cells that causes bacterial
infection.
There is not enough blood distributed to the intestine because of artery blockage.
Rickets causes a child’s bones to become soft and weak, which can lead to bone deformities. The bones affected by rickets can be sore and painful, so the child may be reluctant to walk or may tire easily; the child’s walk may look different (waddling). Children suffering from rickets lack certain vitamin that produce and absorb calcium. What type of vitamin is the one we are looking for?
Vitamin E
Vitamin C
Vitamin A
Vitamin D
Vitamin D
The menstrual cycle, which is counted from the first day of one period to the first day of the next, isn’t the same for every woman. Menstrual flow might occur every 21 to 35 days and last two to seven days. A normal amount of menstrual fluid loss in the form of blood, per period is between 5 mL to 80 mL. The amount is relatively high for some females to suffer anemia. Which among the following vitamins have the capability to produce red blood cells to prevent anemia?
Vitamin B2
Vitamin C
Vitamin D
Vitamin B9
Vitamin B9
