Midterm Review

Macromolecules (biomolecules) that are hydrophobic are:

• Proteins

• Lipids

• Polysaccharides

• Inorganic

A polymer is:

• Monomers that have been bonded together

• A single sub-unit of a biomolecule

• Used to glue things together

What is an example of a biomolecule is used as short term energy storage?

• Starch

• Phospholipids

• DNA

• Lactase

The smallest building block in an organism is...

• Tissue

• Cell

• Organ

• Organ System

List the levels inside an organism from least to most complex.

• Tissue, Organ, Cell, Organ System

• Organ system, organ, tissue, cell

• cell, tissue, organ, organ system

• Organ, Tissue, Organ System, Cell

This biomolecule is used as a long term energy storage source that is beneficial to bears when they go into hibernation.

• Protein

• Carbohydrate

• Nucleic Acid

• Lipid

Enzymes work at at specific temperatures called their optimum temperature. What occurs to the enzyme if the temperature leaves this range?

• The enzyme still works.

• The active site changes shape so the substrate no longer fits

• The enzyme moves to a different area in the body

• The substrate changes shape to fit the new active site

The order of the monomer in nucleic acids is important in determining the proteins made in the body. What are the monomers of nucleic acids?

• Nuclotide

• Amino Acid

• Fatty Acid

• Monosaccharide

The monomers of proteins are...

• Amino Acids

• Nucleic Acids

• Nucleotides

• Glycerol

When the active site of an enzyme changes shape so the substrate can no longer attach, it is said that the enzyme has __________________.

• Changed Shape

• Gotten Bigger

• It's messed up.

• Denatured
