Sucrose is a carbohydrate commonly known as “table sugar” that is formed by the combination of glucose and fructose. The structure of sucrose is show below. Based on this information how would sucrose be characterized?
Polysaccharide
Disaccharide
Monosaccharide
Isosaccharide
Each type of macromolecule may have a monomer and a polymer version which is common in organic chemistry. For example, nylon and Styrofoam are examples of polymers that are produced when smaller monomers react and form chains or networks.
Which monomer is the proper match for the protein polymer?
nucleotides
amino acid
fatty acid
monosaccharide
What is the primary function of the macromolecule represented by the molecules above?
Short term energy storage
Speed up chemical reactions
Store genetic information
Long term energy storage
Below are the structures glucose, galactose and fructose which are some common monomers of carbohydrates. Carbohydrates are a major group of macromolecules found in all living things, which statement below is accurate?
Carbohydrates are a primary energy source for the cell and can provide structural support for living things.
Carbohydrates are used as signaling molecules that control and support metabolism, and signaling of the brain.
Carbohydrates are large molecules involved with cellular support, cell signaling and locomotion.
Carbohydrates are a diverse group of molecules that provide structure for hormones and vitamins as well as energy storage.
Which of the following molecule structures stores genetic information and makes/build proteins?
A
B
C
D
What is the monomer of lipids?
Monosaccharide
Fatty Acid and Glycerol
Amino Acid
Nucleotide
The building blocks for organic compounds are called...
Polygons
Polymers
Monograms
Monomers
Many plants have waxy coatings on some surfaces. This coating reduces water loss because it is not water-permeable. Which of the following types of organic molecule is this waxy coating most likely composed of?
Carbohydrates
Lipids
Proteins
Nucleic Acids
Ovalbumin is a protein found in eggs. Which of the following best describes the molecular structure of ovalbumin?
a chain of amino acids folded and twisted into a molecule
a sequence of nitrogenous bases attached to a sugar phosphate backbone
a set of three fatty acids attached to a molecule of glycerol
a group of six carbon atoms joined in a ring.
Which is shown in the picture?
Monsaccharide
Amino Acid
Fatty Acid
Nucleotide
This is one job proteins do not have in the body.
structure for muscles tissues and organs
transport things through cell membranes or in red blood cells
enzymes which speed up chemical reactions
insulation and long term energy
The parts of a nucleotide are:
nitrogen, sulfur, phosphate group
DNA, RNA, ATP
nitrogenous base, ATP, glucose
nitrogenous base, 5-carbon sugar, phosphate group
Enzymes help break down macromolecules in food so that the body can:
Consume food more slowly
Extract energy and building blocks for cells
Turn macromolecules into minerals
Increase the body’s size without nutrients
