Bio biomolecules
A simple sugar such as glucose is classi ed as a A. monosaccharide B. polysaccharide C. disaccharide D. nucleotide
A
Fat molecules typically contain long chains of carbon atoms. Animals tend to store fats for use when food resources are scarce. This is an advantage to the animal because A. much energy can be gained by breaking the bonds between atoms in the fats B. fats give o carbon dioxide that can be used by the muscles C. amino acids from fat synthesis are more easily digested than carbohydrates D. energy can only be created by digesting fats
A
Cellulose is formed from glucose molecules by a process known as A. hydrolysis B. dehydration synthesis C. cellular respiration D. photosynthesis
B
Organisms combine simple molecules to form complex molecules by the process of A. ingestion B. synthesis C. regulation D. hydrolysis
B

B
Which element is not part of a disaccharide? A. carbon B. nitrogen C. oxygen D. hydrogen
B
Which group consists entirely of organic molecules? A. protein, oxygen, fat B. protein, starch, fat C. water, carbon dioxide, oxygen D. water, starch, protein
B
In which type of molecule is the ratio of hydrogen to oxygen usually 2 to 1? A. lipid B. protein C. carbohydrate D. glycerol
C
Starch molecules are hydrolyzed into smaller units known as A. glycerols B. amino acids C. simple sugars D. proteins 13.
C
Which substance is an inorganic molecule? A. starch B. DNA C. water D. fat
C
Which compound is a polysaccharide? A. glucose B. maltase C. ribose D. starch
D
In living organisms, lipids function mainly as
Sources of stored energy and components of cellular membranes
What are the end products of the hydrolysis of a polysaccharide?
amino acids
During chemical digestion, large food molecules are broken down to smaller food molecules by the process of A. synthesis B. absorption C. hydrolysis D. excretion
c
Two examples of carbohydrates are
