Determine whether each carbohydrate is best described as a monosaccharide, a disaccharide, or a polysaccharide
vazorg [7]

Answer options from an alternative source

  • fructose                              
  • lactose                              
  • starch
  • glucose                                                                            
  • cellulose

Answer:

  • fructose -monosaccharide                              
  • lactose  - disaccharide                            
  • starch  - polysaccharide
  • glucose - monosaccharide                                                                          
  • cellulose - polysaccharide

Explanation:

Monosaccharides are carbohydrates that are the simplest form of a sugar. They cannot be further broken down into smaller carbohydrates, and represent the basic building block for carbohydrates. Monosaccharides can form disaccharides, which are the sugar formed when two monosaccharides join together, or polysaccharides, which are chains of monosaccharides.

Answer:

Explanation:

A substance that produces an excess of hydroxide ion (-OH) in aqueous solution.

       This is an arrhenius Base

According to the arrhenius theory, a base is a substance that combines with water to produce excess hydroxide ions, OH⁻ in an aqeous solution. Examples are :

  • Sodium hydroxide NaOH
  • Potassium hydroxide KOH

A substance that produces an excess of hydrogen ion (H+) in aqueous solution

      This is an arrhenius Acid

An arrhenius acid is a substance that reacts with water to produce excess hydrogen ions in aqueous solutions.

Examples are;
