On your own paper, draw the Kekule structures and line-bond formulas for both butane
and hexane. When you have drawn the structures, enter a note in the answer box
indicating you have done so (e.g., "I completed these drawings." Or "I drew the
structures for butane and hexane.")
How are the aldehyde and ketone functional groups similar? Different?
Aldehdyes and ketones both have a carbon double bond oxygen arrangement (C=O) in
their structure. They differ in that the other two bonds that the carbon forms are
different. A ketone has both bonds connected to other carbons. An aldehyde has one
bond to hydrogen and the second bond to either another hydrogen or carbon.

A cell wall is a combination of carbohydrates and proteins. What level of organization
would this indicate and why?
Supramolecular complex. A cell wall is a combination of two types of macromolecules to
form a larger complex (through non-covalent interactions).
What is the monomer of proteins, carbohydrates, and DNA?
The protein monomer is an amino acid, a monosaccharide is the monomer for
carbohydrates, and a nucleotide is the monomer for DNA.
How are prokaryotes and eukaryotes different? (State your answer in two or more
complete sentences.)
While they are both cells types, prokaryotes have a simple structure with no organelles
present. Eukaryotes have a true nucleus and organelle structures. As a result, the
eukaryotes are also considerably larger than prokaryotes.
How are Bacteria and Archaea different? (State your answer in two or more complete
sentences.)
Bacteria and Achaea are both simple cells with no organelle structure, and they lack a
true nucleus. Archaea live in extreme conditions, such as hot springs and in the artic;
they are thought to be more closely related to prokaryotes.
What is the function of mitochondria, lysosomes, and vacuoles?
The mitochondria is the powerhouse of the cell responsible for producing ATP. It also
contains metabolic processes that yield ATP in the end. - Lysosomes degrade
macromolecules-protein, lipid, carbohydrate, nucleic acids-into smaller pieces. These
organelles have an acidic pH. Vacuoles have digestive enzymes to degrade proteins,
carbohydrates, and nucleic acids, plus vacuoles function largely as storage centers.
What energy molecule is produced in the mitochondria?
Adenosine triphosphate (ATP)
