Chemistry comes alive Flashcards
Twelve most abundant chemical elements in the body
Carbon Hydrogen Oxygen Nitrogen Phosphorus Sulfur Potassium Magnesium Calcium Sodium Chlorine
Functions of hydrogen bonds
It creates a very high surface tension.
Differentiate between organic and inorganic compounds
Inorganic compounds usually lack carbon and are structurally simple whereas organic compounds always contain carbon and usually contain hydrogen.
Examples of inorganic compounds
water and minerals(Na, Mg, K)
Examples of organic compounds
fat, protein, carbohydrates, nucleic acids
Functions of water in the body
As a solvent
In chemical reactions
As a heat absorber
As a lubricant
The function of Deoxyribose
The genetic code in chromosomes.
The function of Oligosaccharides
“Self” antigens in our cell membranes.
The function of Glycogen
The storage form for glucose in the liver.
The function of True fats
The storage form for excess food in adipose tissue.
The function of Cholesterol
The precursor molecule for the steroid hormones.
The function of Fiber
The undigested part of food that promotes peristalsis.
The function of Nucleotides
The sugars that are part of the nucleic acids.
The role of “Carbon Dioxide” in cellular respiration
Carbon dioxide is a waste product that moves from the cells into the blood to be carried to the lungs and eventually exhaled.
The role of “Heat” in cellular respiration
Heat produced contributes to normal body temperature.
