Biology Carbohydrates

What elements make up carbohydrates?

• Carbon, hydrogen, nitrogen, oxygen
• sulfur, carbon, hydrogen
• glucose and fructose
• carbon, hydrogen, oxygen

How many categories of carbohydrates are there? 

• 1
• 2
• 3
• There are no categories

The 3 categories of carbohydrates are:

• Monosaccharide, disaccharide, polysaccharide
• glucose, fructose, galatose
• starch, cellulose, chitin
• There are no categories of carbohydrates

What two groups are removed from monosaccharides to form disaccharides or polysaccharides

• water and oxygen
• hydrogen and hydroxyl group
• carbon and hydrogen
• water and carbon

These are all properties of a monosaccharide EXCEPT:

• simple sugar
• 1:2:1 ratio
• double sugar
• used for energy

These are all properties of a disaccharide EXCEPT:

• made up of two sugars
• sucrose
• 2 monosaccharides joined by dehydration synthesis
• ratio of 1:2:1

How do the number of H atoms compare to the number of O atoms in a carbohydrate?

• There are TWICE as many H
• They are the same amount
• There are THREE times as many H
• There are TWICE as many O

All carbohydrate names end with which ending:

• ise
• ase
• ese
• ose
