Questions and CORRECT Answers
True/False. A virus is considered a microorganism. - CORRECT ANSWER - False,
Viruses are not living and as such are not considered microorganisms. Viruses can, however, be
classified as microbes, a more general term that includes microorganisms and viruses.
What is the smallest biological unit of life? - CORRECT ANSWER - A cell
What are the four main types of macromolecules found in cells? - CORRECT ANSWER -
Proteins, Lipids, Nucleic Acids, Carbohydrates
Proteins are formed from various combinations of - CORRECT ANSWER - Amino acids
There are how many known forms of amino acids - CORRECT ANSWER - twenty
How many amino acids are classified as being essential amino acids? - CORRECT
ANSWER - Nine
Where can the two major types of nucleic acids be found in the cell? - CORRECT
ANSWER - DNA, RNA. Found in the nucleus.
What is the role of RNA? - CORRECT ANSWER - RNA , found in the nucleus is capable
of leaving the nucleus. RNA is repsponsible for deciphering the hereditary information in DNA
and uses it to synthesize proteins.
What is the role of DNA? - CORRECT ANSWER - DNA, found in the nucleus contains
vast amount of hereditary inforamtion, responible for inhereitable characteristic os living
organisms.
,Complete the following RNA strand, and indicate how many bonds are formed for each
complementary pair:
3' GGUCAUCG 5'5' CC AGC 3' - CORRECT ANSWER - 3' GGUCAUCG 5'5'
CCAGUAGC 3'There are 2 bonds formed between A and U, and 3 bonds between G and C.
The plasma membrane - CORRECT ANSWER - Restricts movement of materials in and
out of the cell & Prevents essential nutrients from escaping
How many carbon atoms are present in glucose? - CORRECT ANSWER - 6
True of False: The genetic material within a prokaryotic cell is contained within a membrane-
enclosed region. - CORRECT ANSWER - False
Only eukaryotic cells contain its genetic material within a nucleus.
True or False: Prokaryotic cells can be subdivided into Bacteria and Archaea. - CORRECT
ANSWER - True
True or False: Archaea is noted for its ability to survive under harsh conditions.
Correct! - CORRECT ANSWER - True
Archaea can often be found in harsh conditions such as high salt levels, high acid conditions,
high temperatures and even oxygen-poor conditions.

CORRECT ANSWER - Animalia, Plantae, Fungi, Protista
Microorganisms classified as Plantae obtain most of their energy by converting [answer1] energy
into [answer2] energy. - CORRECT ANSWER - 1. Light (sunlight)
2. chemical (sugars)
, Which of the following are considered Protista? Select all that apply. - CORRECT
ANSWER - Algae, Amoeba
The function of the ribosome is - CORRECT ANSWER - Protein synthesis
True or False: Protista retain a unicellular classification, as they are unable to form tissue layers.
- CORRECT ANSWER - True
Where are ribosomes located? - CORRECT ANSWER - cytoplasm of prokaryotic cells
and in the ER of eukaryotic cells.
The combination of the cell membrane and the outer membrane is referred to as the - CORRECT
ANSWER - Cell envelope
The function of the mitochondria is - CORRECT ANSWER - To produce energy (ATP)
True or False. All multicellular microorganisms classified as Animalia are autotropic. -
CORRECT ANSWER - False
True or False: Metabolism is a controlled set of biochemical reactions that occur in living
organisms in order to maintain life. - CORRECT ANSWER - True
True or False: Enzymes slow down chemical reactions to conserve energy. - CORRECT
ANSWER - False
What is a cofactor? - CORRECT ANSWER - A cofactor is a small chemical component
that assists an enzyme during the catalysis reactions. A cofactor is usually metal ions.
Define catabolism - CORRECT ANSWER - Catabolism is the process of breaking down
larger molecules into useful energy sources.
