20

How many carbon atoms are present in glucose?

6

Define an essential amino acid.

An essential amino acid cannot be produced by the human body and as such must be take in from the environment through alternative sources (i.e) food.

Which of the following microorganisms are considered to be Eukarya? Select all that apply.

Animalia, Plantae, Fungi, Protista.

What is the smallest biological unit of life?

Cell

True of False: The genetic material within a prokaryotic cell is contained within a membrane-enclosed region.

False - Only eukaryotic cells contain its genetic material within a nucleus.

The plasma membrane (select all that are true):

Is often a bilayer comprised of lipids & Contains hydrophobic tails pointing inward

The function of the mitochondria is (select all that apply):

Mitochondria are considered the power plant of the cell, as it produces ATP.

A defining characteristic of fungi is the presence of chitin in the cell walls. Which of following also contain chitin? Select all that apply.

Mushrooms, Yeast, Mold

Plantae

Cell walls are found in which of the following (select all that apply):

Plants, Fungi, bacteria, Algae

The function of the ribosome is (select all that apply):

Protein Synthesis - Ribosomes are located in the cytoplasm of prokaryotic cells and in the ER of eukaryotic cells.

What are the four main types of macromolecules found in cells?

Proteins, Lipids, Carbohydrates, & Nucleic Acids

What are the two major types of nucleic acids and their roles?

There are two major types of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). Nucleic acids are chemical molecules that carry genetic information within the cell. DNA contains a vast amount of hereditary information and is responsible for the inheritable characteristics of living organisms. RNA is responsible for deciphering the hereditary information in DNA and using it to synthesize proteins.

True of False. All multicellular microorganisms classified as Animalia are heterotrophic

True

True or False: Prokaryotic cells can be subdivided into Bacteria and Archaea.

True

True or False: Protista retain a unicellular classification, as they are unable to form tissue layers.

True

True/False. A virus is classified as a microbe.

True - Although viruses are not living and as such are not considered microorganisms, they can, however, be classified as microbes, a more general term that includes microorganisms and viruses.

True or False: Archaea is noted for its ability to survive under harsh conditions.

True - Archaea can often be found in harsh conditions such as high salt levels, high acid conditions, high temperatures and even oxygen- poor conditions.
