True/False. A virus is considered a microorganism. - correct answerFalse, 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 answerA cell
What are the four main types of macromolecules found in cells? - correct
answerProteins, Lipids, Nucleic Acids, Carbohydrates
Proteins are formed from various combinations of - correct answerAmino acids
There are how many known forms of amino acids - correct answertwenty
How many amino acids are classified as being essential amino acids? - correct
answerNine
Where can the two major types of nucleic acids be found in the cell? - correct
answerDNA, RNA. Found in the nucleus.
What is the role of RNA? - correct answerRNA , 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 answerDNA, 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 answer3' 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 answerRestricts movement of materials in and out of
the cell & Prevents essential nutrients from escaping
How many carbon atoms are present in glucose? - correct answer6
, True of False: The genetic material within a prokaryotic cell is contained within a
membrane-enclosed region. - correct answerFalse
Only eukaryotic cells contain its genetic material within a nucleus.
True or False: Prokaryotic cells can be subdivided into Bacteria and Archaea. - correct
answerTrue
True or False: Archaea is noted for its ability to survive under harsh conditions.
Correct! - correct answerTrue
Archaea can often be found in harsh conditions such as high salt levels, high acid
conditions, high temperatures and even oxygen-poor conditions.
Which of the following microorganisms are considered to be Eukarya? Select all that
apply. - correct answerAnimalia, Plantae, Fungi, Protista
Microorganisms classified as Plantae obtain most of their energy by converting
[answer1] energy into [answer2] energy. - correct answer1. Light (sunlight)
2. chemical (sugars)
Which of the following are considered Protista? Select all that apply. - correct
answerAlgae, Amoeba
The function of the ribosome is - correct answerProtein synthesis
True or False: Protista retain a unicellular classification, as they are unable to form
tissue layers. - correct answerTrue
Where are ribosomes located? - correct answercytoplasm 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 answerCell envelope
The function of the mitochondria is - correct answerTo produce energy (ATP)
True or False. All multicellular microorganisms classified as Animalia are autotropic. -
correct answerFalse
True or False: Metabolism is a controlled set of biochemical reactions that occur in living
organisms in order to maintain life. - correct answerTrue
True or False: Enzymes slow down chemical reactions to conserve energy. - correct
answerFalse
What is a cofactor? - correct answerA cofactor is a small chemical component that
assists an enzyme during the catalysis reactions. A cofactor is usually metal ions.
